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…
My research has always focused on the behavior of strongly correlated systems. This project furthers this line of research. It can be divided into big groups, according to the physical characteristics of the systems of interest: correlated homogeneous ("clean") and disordered systems. In the former case, we are interested in bosonic or fermionic systems, showing competition between locali…
This project focuses on condensed matter systems whose electronic properties are dominated by correlation effects. The problems to be studied can be divided in three classes: a) correlated systems with low dimensionality; b) magnetic or superconducting systems; c) disordered systems. The envisaged approach, which encompasses a variety of techniques going from the traditional to the innova…

In this project, we plan to study models of multi-band superconductors with d-symmetry with competition between pairings with different symmetries. In particular, we will focus initially on systems with two quasi-twodimensional bands with intra-band pairing with B2 symmetry, cos(2\theta), and inter-band interactions (attractive or repulsive) with B1 symmetry, sin(2\theta) (where we used t…
In the present project we propose the study of Weyl semimetals and topological superconductors in the presence of quantum impurities. To do so we consider a system composed by a Weyl semimetal with multiple nodes, the so-called multi-Weyl semimetal, coupled to magnetic impurities via a Kondo-type Hamiltonian. Moreover, we will analyze how the presence of quantum impurities affects systems…
Our goal in this project is the study of models of resistive switching in disordered dielectrics close to a metal-insulator transition through random resistor network models with heat diffusion. The models consist of a two-dimensional lattice of random resistors whose voltage and current distributions are obtained from the solution of Kirchhoff's circuit equations. The diffusion equation …

We describe here the main physical properties of unconventional high-temperature superconductors containing iron in their structures, the so-called iron-based superconductors (FeSCs). The phase diagram of these materials exhibits a plethora of collective fluctuations besides superconductivity, which includes a long range magnetic ordering of the stripe-type and also nematic order. In most…
In this project we intend to study Floquet topological insulators, i.e., topological states of matter induced in systems initially in the trivial phase by a time-dependent periodic Hamiltonian. We will consider imperfections in various aspects of the system, arising either from decoherence from the environment, from disorder within the sample or from incoherence of the radiation. (AU)
