37 Pulse propagation in topological photonic crystals Albert Ferrando Cogollos albert.ferrando@uv.es FOTO Photonic crystals are periodic dielectric structures with exceptional properties that allow the control of the flow of light in multiple ways, similar to how electronic crystals control electrical currents. Very recently, it has been shown that a particular form of photonic crystals gives rise to a new panoply of phenomena that mimic the behavior of electrons in a new type of insulating materials whose properties are based on subtle mechanisms of topological origin, called topological insulators. These new photonic structures are known as topological photonic insulators and can be considered a new type of photonic crystal with finely tuned geometries that emulate their electronic counterparts. They permit new forms of localization and propagation of light not achievable in conventional photonic devices. Due to the novelty of this new category of photonic structures there are still interesting aspects to explore, particularly those related to the propagation of optical pulses

The objective of this proposal is to analyze the behavior of optical pulse propagation in certain types of one-dimensional topological photonic crystals with unconventional dispersion properties. This study will use a rich combination of analytical and numerical techniques to reveal the most interesting properties of pulse evolution in these structures. These tools are closely related to those presented to students in different subjects in the Photonics track of our Master's Degree in Advanced Physics. Therefore, this master's thesis proposal can be an excellent introductory means to develop more in-depth research in the very active area of Topological Photonics or in analogous areas, such as Topological Insulators in Condensed Matter Physics.

48 Electron beam interactions with CNT nanowires Javier Resta López; Jorge Giner-Navarro javier2.resta@uv.es FOTO Due to their unique geometry and exceptional electro-optical and thermo-mechanical properties, carbon nanotubes (CNTs) have found applications across various scientific and technical fields. Recently, they have garnered attention in particle accelerator physics, where CNT arrays show promise for beam manipulation and acceleration.

50 Optical Spectroscopy of Two-dimensional Materials Andres Granados del Aguila andres.granados@uv.es FOTO Next technological revolution relies on the realization and manipulation of quantum degrees of freedom at room temperature. In this regard, layered materials hold great potential for advanced optoelectronic applications. Using the straightforward yet famous “scotch tape method”, single atomically-thin layers can be obtained. Beyond graphene, the first isolated two-dimensional (2D) material, many other layered materials exhibits striking optoelectronic properties.

In this project, we are looking for highly motivated students to investigate light-emission phenomena in atomically thin layers of transition metal dichalcogenides (TMDs). Monolayer TMDs provide an unprecedented platform where exotic light-matter interactions and quantum phenomena become accessible under everyday conditions. For example, monolayer TMDs exhibit strong light absorption and emission at room temperature, arising from tightly bound electron–hole pairs (excitons). These tiny excitons display ultrafast dynamics as well as nonlinear optical and transport properties that could pave the way for advanced device functionalities.

In addition, the project offers a comprehensive training, from hands-on advance quantum materials fabrication to programming. The project is ideal for students eager to dive into cutting-edge quantum semiconductor research.

57 The ghost sector of QCD Joannis Papavassiliou joannis.papavassiliou@uv.es TEO The procedure of quantization in covariant gauges is inextricably connected with the appearance of the so-called "ghost" fields, which are spin zero particles that obey Dirac statistics. The description of such fields is implemented through  the introduction of Grassmann variables, and the specifics of the quantization are known as the Faddeev-Popov Ansatz. The presence of the ghosts has profound implications for the economy of the theory, assuring, among others, the unitarity and the renormalizability . The proposal focuses on studying in detail the ghost sector, and understanding the most characteristic aspects of the dynamics associated to it.   
58 Dark Monopoles Vicente Vento vicente.vento@uv.es TEO Monopoles have been a subject of much theoretical and experimental research since they were proposed to symmetrize Maxwells equations. However, no experimental signature of their existence has been detected. Many mechanisms have been proposed to explain this lack of success. In here we generalize QED to a two photon theory where the magnetic photon and the monopole belong to dark matter. A naive mixing interaction produces duality and generates experimental consequences for indirect monopole detection via the magnetic
charge of the electron or the electric charge of the monopole. The thesis will investigate some of these experimental scenarios.
59 Higgs mediated dark Showers José Zurita jzurita@ific.uv.es TEO  A strongly interacting dark sector can give rise to ``dark showers,'' akin to parton showers in QCD. This project aims to study the dark showers mediated by a heavy scalar that can mix with the SM Higgs, paying special attention to the parameter space to be explored in the next run of the LHC.
60 Angular response of resonant cavities to gravitational waves Camilo Alfredo García Cely  camilo.garcia@ific.uv.es TEO The project will focus on the analytical study of how resonant cavities can act as detectors for gravitational waves, emphasizing their angular response and antenna pattern. It will develop theoretical models describing the excitation of electromagnetic modes by gravitational perturbations and analyze how these effects vary with the direction and polarization of the incoming waves. The formalism will rely on spherical harmonics to characterize the angular dependence and to derive analytical expressions for the coupling efficiency between gravitational and electromagnetic modes. The study aims to identify measurable signatures and establish a rigorous theoretical framework to guide the design and interpretation of future cavity-based gravitational wave detection experiments.
61 Line-shining-through-a-wall from spin-2 particles at ALPs II  Camilo Garcia Cely  camilo.garcia@ific.uv.es TEO “Light-shining through a wall” (LSW) refers to an experimental scheme in which photons convert into a new weakly interacting particle (such as an axion or axion-like particle) before a barrier, traverse the barrier unimpeded, and reconvert back into photons behind the barrier. In the ALPS II experiment at DESY, this technique is used to search for light bosons like ALPs by using high-finesse optical cavities on both sides of an opaque wall to amplify conversion and reconversion rates.  

In this project we generalize the LSW concept to spin-2 particles (tensor modes). Photons could convert into spin-2 particles (which may be related to graviton modes, Kaluza-Klein gravitons in extra-dimensional theories, or other tensor excitations). These spin-2 modes traverse the barrier and then reconvert back into photons. This opens a channel of “line-shining through a wall” mediated by tensor couplings.
62 Neutrino Fog: A Gateway to New Physics Martín González Alonso y Sergio Palomares martin.gonzalez@ific.uv.es, Sergio.Palomares.Ruiz@ific.uv.es TEO The first measurements of the so-called neutrino fog (nuclear recoils induced by solar neutrinos) have been recently reported. This project will study how to use this measurement, in a very simplified setup, to probe non-standard interactions.
63 Gravitational interactions from scattering amplitudes in high-energy colliders Germán RODRIGO german.rodrigo@csic.es TEO Recently, powerful Quantum Field Theory techniques, originally developed to predict observables in high-energy colliders, have been applied to describe classical observables relevant to gravitational wave physics. This has motivated a proliferation of approaches to extract classical information from quantum scattering amplitudes. These investigations suggest that the basis of the dynamics of General Relativity is Yang-Mills theory. The project consists in determining the deflection of light by a massive spinless/spinning object using the novel Worldline Quantum Field Theory (WQFT) formalism for classical scattering.
64 Efficient Quantum Simulation of Lattice Gauge Theories with Improved Hamiltonians Wanqiang Liu and Manuel Gessner manuel.gessner@uv.es TEO We will benchmark improved Hamiltonians for Z_2 lattice gauge theory, which reduce qubit needs by a factor 2^d, offering an advantage in the NISQ era. By fixing gauge redundancy and testing on available quantum computers we aim to optimize resources and guide realistic lattice simulations.
65 Coherent elastic neutrino-nucleus scattering and direct dark matter detection Valentina De Romeri deromeri@ific.uv.es TEO Coherent elastic neutrino-nucleus scattering (CEvNS) is a neutral-current process where a neutrino interacts coherently with an entire nucleus. It offers a sensitive test of the Standard Model and a probe for new physics. Since its signals mimic those from dark matter, understanding CEvNS is essential for advancing future direct dark matter searches.
66 The study of emergence Veronica Sanz veronica.sanz@uv.es TEO Emergence means that when many simple units interact, new collective patterns or “laws” appear at the macroscopic level that are not obvious from the microscopic rules. Emergence is central to how physicists think about complex systems. Many-body systems can display coherent patterns (flocks, lanes, waves) even when each unit follows only primitive rules. This “order from simple rules” is a clean playground for emergence, coarse-graining, and the spirit of effective theories: macroscopic descriptors (order parameters, correlation lengths) summarize vast microscopic detail. You’ll implement a minimal flocking model and measure how global order “turns on” as parameters vary—analogous to a phase transition.
67 Development of a neutrino evolution simulation and data analysis framework Roberto Ruiz de Austri rruiz@ific.uv.es TEO The project will entail the development of a software for the efficient computation of neutrino production and evolution, focusing on the implementation of models that simulate the atmospheric neutrino production, their evolution while propagating and the resulting neutrino spectra expected at a generic neutrino detector. It will require to account for non-linear dynamics such as the neutrino oscillation in matter and their absorption while crossing the Earth, using preferably semi-analytic algorithms to achieve high numerical efficiency. The resulting software will be employed to perform statistical analyses of real data of atmospheric neutrino events from the IceCube experiment.
68 "Goofy" symmetries Miguel Nebot Gómez Miguel.Nebot@uv.es TEO In 2023 relations among parameters of 2 Higgs doublets potentials were shown to be stable under renormalization group evolution, despite not corresponding to the known symmetries of such models. "Goofy" transformations can explain that fact. The goal is to study them, and additional applications.
69 Peccei-Quinn symmetries and axion phenomenology.  Oscar Vives, Marco Ardu oscar.vives@uv.es TEO One of the mysteries of the SM is the absence of the theta term in the Lagrangian, allowed to be O(1), but constrained to $<10^{-10}$ by EDM limits. The Peccei–Quinn mechanism dynamically relaxes this angle to zero and predicts a light pseudo–Goldstone boson, the axion, whose phenomenology we plan to study.
70 Factorisation Violation Leandro Javier Cieri lcieri@ific.uv.es TEO We study QCD factorisation breaking by analysing the soft-gluon current at tree-level up to N4LO. This novel approach probes the limits of standard perturbative assumptions, providing new insights into the all-order structure of QCD scattering amplitudes.
71 Electroweak corrections for LHC phenomenology Leandro Cieri lcieri@ific.uv.es TEO We propose to augment the DYTurbo code by incorporating the most advanced electroweak (EW) corrections for Drell-Yan, Higgs, and top-quark pair production. This combination with high-order QCD effects will provide the new benchmark for theoretical predictions at the LHC.
72 Singular limits in MultiHiggs scalar potentials Miguel Nebot Gómez Miguel.Nebot@uv.es TEO In MultiHiggs scalar sectors shaped by some discrete symmetry, (i) assuming an invariant vacuum or (ii) alternatively approaching that symmetric regime, can yield very disparate properties (e.g. mass spectra). The goal of this proposal is to explore that kind of situation and its consequences.
73 Proton decay from leptoquarks Claudia Hagedorn claudia.hagedorn@ific.uv.es TEO The possibility of proton decay in extensions of the Standard Model is studied. In particular, proton decay channels induced by leptoquarks are considered. These are scalar or vector particles that couple to leptons and quarks. Options to constrain the couplings with new symmetries are explored.
74 Estados de Efimov en un sistema de tres mesones encantados Raquel Molina Peralta Raquel.Molina@ific.uv.es TEO Cuando dos partículas pueden interaccionar dando lugar a una resonancia debido a fuerzas de atracción de corto alcance dentro del sistema de tres cuerpos, puede tener lugar el fenómeno llamado efecto Efimov, que fue descrito por primera vez en la década de 1970, en donde surgen un número infinito de estados ligados de tres cuerpos. En este TFM proponemos estudiar la interacción de tres mesones D* y como esta puede dar lugar a estados de Efimov. [1] V. Efimov, Phys. Lett. 33B, 563 (1970).V. Efimov, Nat. Phys. 5, 533 (2009).

75 Buscando materia oscura ligera en el sector escalar Emilie Passemar emilie.passemar@ific.uv.es TEO En este trabajo comprobaremos la existencia de nuevas partículas escalares ligeras. La introducción de nuevas partículas de este tipo permite responder a ciertas preguntas abiertas en cosmología, como por ejemplo la existencia de materia oscura o la inflación.
Sin embargo, la desintegración de estas partículas escalares con energías del orden de GeV es muy difícil de abordar, ya que implica tratar la interacción fuerte a baja energía en su régimen no perturbativo. En este trabajo nos proponemos mejorar los modelos de desintegración de estos escalares en hadrones utilizando métodos dispersivos. A continuación, intentaremos encontrar o restringir estas nuevas partículas utilizando los resultados experimentales existentes. 
77 Resolución de teorías de campos escalares con acoplamiento cuártico mediante redes neuronales Noemi Rocco, Alessandro Lovato rocco@ific.uv.es TEO El objetivo principal de este trabajo es emplear un ansatz basado en redes neuronales para obtener cotas superiores variacionales coherentes con los resultados perturbativos en teorías de campos escalares en dimensiones d=0+1y d=3+1, y para distintos valores del acoplamiento λ. El proyecto también contempla como objetivos adicionales el cálculo de autovalores por encima del estado fundamental y la aplicación de este enfoque a otras teorías de campos cuánticos. 
78 Resource Theories in Quantum Information Science Manuel Gessner manuel.gessner@uv.es TEO Quantum resource theories provide a unified framework to understand which properties make certain tasks in quantum information possible.
