• Research project: Physical modeling and simulation of integrated optical microcavities for the development of photonic sensors applied to environmental monitoring assisted by artificial intelligence.

• Research fields: Solid state nanostructures

We aim at the physical modeling and simulation of integrated optical microcavities aimed at the development of high-sensitivity environmental photonic sensors. The goal is to understand and describe the resonant behavior of these structures under conditions of extreme electromagnetic confinement, using advanced numerical methods such as the Finite-Difference Time-Domain (FDTD) method and the Finite Element Method (FEM) to analyze optical propagation and losses across different geometric configurations. Furthermore, the project proposes the incorporation of artificial intelligence tools, particularly physics-informed machine learning approaches (Physics-Informed Machine Learning), to predict spectral shifts and the quality factor of resonant modes.

• Research field:  Non-equilibrium processes, Cold atoms and optical lattices, Cold molecules

Cold heavy molecules such as FrO are promising platforms for laser cooling and precision measurements probing fundamental symmetries. We carry out a theoretical study of the FrO molecule to explore its potential in these contexts. Using relativistic multireference methods, we investigate its electronic structure and potential energy surfaces, and examine molecular properties relevant to cold-molecule and precision-measurement studies.

• Research project: Optimization of the Schrödinger-Poisson model using B-splines

• Research field: Formation of cosmological structures

The large scale-structures in the universe can be studied through the relationship between N bodies that interact gravitationally. In our case, we propose an approximation to this process by determining a quantum dust fluid in one spatial dimension, known as Schrödinger-Poisson. The evolution of the Schrödinger-Poisson equations is performed using B-splines in the Crank-Nicolson propagation for the predictor-corrector scheme. Different cosmological models are analyzed and the matter power spectrum is determined. We hope to reduce the computation time in order to consider parameters that replicate better results.

• Research project: deEfficiency of a Thermal Machine Supplied by Dissipative Quantum Correlations

• Research field:  Conceptual foundations of quantum theory, Quantum computation and quantum information, Non-equilibrium processes

A thermal machine that uses correlations between quantum objects as a physical resource can significantly improve its performance.

In this machine, the working substance can be a bipartite system of correlated qubits, one of which is subjected to a heat reservoir and the other to a cold reservoir. Such a thermal machine operating under adiabatic conditions can exhibit increased efficiency compared to the classical Carnot limit.

This thesis proposes studying such a machine while considering quantum decoherence in the working substance and its effect on entropy production and the consumption of quantum correlations during the complete thermodynamic cycle.

• Research project: Coherent Raman Spectroscopy Based on Interference of Entangled Photon Pairs

• Research field: Ultrafast spectroscopy, Quantum optics

This project proposes a quantum-enhanced coherent Raman spectroscopy scheme using entangled photon pairs to overcome classical limits in temporal and spectral resolution. By integrating SU(1,1) interferometry and the principle of induced coherence, the protocol enables high-precision sensing with natural immunity to environmental noise and losses. The research utilizes analytical modeling and numerical simulations to demonstrate how non-classical light correlations can extract vibrational signatures more efficiently than traditional methods. Ultimately, this framework provides a theoretically robust and experimentally feasible pathway for high-sensitivity molecular characterization.

• Research project: Towards a dimer renormalization group flow for the Bose-Hubbard model

• Research field: Cold atoms and optical lattices

Study the static properties of the Bose Hubbard model in the thermodynamic limit —that is, in the regime of a large number of bosons and lattice sites using a block decimation renormalization group (RG) scheme. The approach consists of partitioning the original chain into blocks formed by dimers (pairs of contiguous sites) and successively applying a renormalization transformation to these configurations. The main objective is to analyze the flow of non local observables, such as particle density or energy density in subintervals of the chain, under this coarse graining scheme. The study will also aim to identify the possible existence of fixed points in the flow, which could be associated with the presence of quantum phase transitions in the system.

• Research project: Experimental implementation of a Quantum Key Distribution protocol

• Research field: Quantum computation and quantum information

Quantum key distribution (QKD) protocols offer a layer of security based on the principles of quantum mechanics and replace classical encryption methods that have become vulnerable with the advent of quantum computing. At the time, there have been several QKD protocol implementations with BB84 being one of the oldest and more popular ones. As these protocols evolve, so does research about their potential vulnerabilities, making this a field in constant evolution. As such, this work will aim at understanding the limitations and vulnerabilities of QKD protocols and implement a secure, cost-effective and efficient quantum communication channel.

• Research project: Dynamics of the Helium Atom under the Interaction with Ultrashort Pulses

• Research field:  Atomic and molecular physics

We aim to study the transition probabilities from the ground state of the helium atom to doubly excited states, induced by ultrashort pulses in the femtosecond and attosecond regimes. To this end, a numerical code will be developed to simulate the time evolution of the helium atom under the interaction with such pulses.

This theoretical approach seeks to model electronic dynamics in multielectronic systems and to analyze atom–radiation interactions on ultrashort timescales. The results of this project will contribute to a deeper understanding of fundamental processes in multielectronic systems and their response to intense and ultrashort electromagnetic fields, with potential applications in atomic physics and ultrafast optics.

• Research project: Using a Hong-Ou-Mandel interferometer to characterize single-photon pair indistinguishability and carry out a quantum optical coherence tomography protocol

• Research field:  Quantum optics

The Hong-Ou-Mandel (HOM) interference is a two-photon interference phenomenon that has shown a great potential to be applied in different (quantum) optical tasks, namely the study of the degree of indistinguishability for a pair of photons or the morphology of a sample through the so-called quantum optical coherence tomography (QOCT) protocol. In this work, we implement a HOM interferometer to carry out such mentioned tasks: for one hand, characterizing how indistinguishable the entangled photon pairs generated from the spontaneous parametric down-conversion (SPDC) process occurring in a β-BBO nonlinear crystal, and on the other hand, characterizing the internal structure of a single-layer transparent sample.
