About the Project

This project focuses on some important problems in the physics of quantum materials. These are materials that allow the exploration of emerging quantum phenomena with potential applications in future technologies.

The types of systems we devote our efforts to include transition metal oxides, heavy fermion systems, unconventional superconductors, quantum spin liquids, doped semiconductors, topological insulators, quantum Hall systems, and others.

We particularly aim to focus on:

  • Electronic correlation effects.
  • Disorder effects.
  • Topological properties.
  • Quantum thermodynamic aspects at the nanoscale.
  • Development of numerical tools to address these challenging problems.

We are interested in determining phase diagrams, thermodynamic and transport properties, as well as the responses of these systems to externally applied protocols, both near and far from thermodynamic equilibrium, and the conditions under which certain desired behaviors or characteristics can be achieved or controlled.

These objectives involve both analytical approaches based on well-established tools, such as:

  • Perturbation theory
  • Renormalization group
  • Auxiliary particle techniques
  • Mean field theory

And state-of-the-art numerical techniques, such as:

  • Density matrix renormalization group.
  • Tensor network methods.
  • Numerical renormalization group of Wilson.
  • Monte Carlo method.
  • Dynamical mean field theory.

The project team consists of researchers from the Gleb Wataghin Institute of Physics at the University of Campinas (UNICAMP) and the Institute of Physics at the University of São Paulo (USP).
