This project focuses on some important problems in the physics of quantum materials. These are materials that allow us to explore emergent quantum phenomena with potential uses in future technologies. The types of systems to which we devote our efforts are transition metal oxides, heavy fermion systems, unconventional superconductors, quantum spin liquids, doped semiconductors, topologica…
Electronic systems whose properties are influenced by symmetries and topological aspects of the band structure have been actively studied in the past few years. Examples include materials such as graphene, topological insulators and superconductors, and Weyl semi-metals. This research project proposes to investigate some fundamental theoretical questions which, in spite of the rapid advan…

The exploration of non-Hermitian Hamiltonians in the context of open quantum systems has gained significant interest in recent years. This direct doctorate research project aims to introduce the student to a research program in these fascinating topics. Concretely, the project goals are two-fold: (i) to establish a generic platform to study non-Hermitian quantum many-body systems; and (ii…
Spin and charge fluctuations have been proposed to be the driven pairing mechanism of several unconventional superconductors, including different systems such as iron pnictides, and cuprates. The usual approach to treat these fluctuations is the zero-temperature theory of matrix-Random-Phase Approximation (matrix-RPA). Based on our previous work on the orbital- and sublattice-dependent ma…
The project aims to investigate the metal-insulator transition (MIT) in the particle-hole asymmetric Hubbard model. The study revisits this interesting problem by focusing on the behavior of the chemical potential at the critical point of the Mott transition and by employing methods such as exact diagonalization and the Density Matrix Renormalization Group (DMRG). Special attention is gi…
Magic-angle twisted bilayer graphene (MATBG) is a fascinating system that displays a plethora of intriguing physical phenomena such as correlated insulators, superconductivity, and unconventional quantum Hall effects, among others. Several recent experiments have demonstrated the rich electronic properties of MATBG, which exhibits correlated insulating and superconducting phases. In spite…
This project proposes a theoretical and original assessment of the thermodynamic properties of quantum systems subject to continuous measurements. This is currently one of the main methods used in quantum coherent experiments. However, its thermodynamic aspects are only now starting to be understood. This project is relevant, as it treats an extremely current topic of research, which is o…

Obtaining non-abelian anyons is one of the major goals within the field of topological states of matter. The simplest of these anyons, Majorana bound states, have been proposed as candidates for implementing topological quantum computation relying on its non-abelian statistics. Parafermions can be regarded as ZN generalizations of the Z2-symmetric Majorana bound states. They have a richer…
