Rodrigo Pereira holds a bachelor?s (2001) and a masters (2004) degree in physics from the State University of Campinas. He received his PhD (2008) from the University of British Columbia, in Vancouver, Canada. He was a postdoctoral researcher (2008-2010) at the Kavli Institute for Theoretical Physics at the University of California Santa Barbara and an assistant professor (2010-2019) at the Sao Carlos Institute of Physics, University of Sao Paulo. From 2016 to 2019 he was a visiting professor and group leader at the International Institute of Physics (IIP-UFRN). Since 2019 he is an assistant professor at UFRN. His research is in the field of theoretical condensed matter physics, with focus on quantum magnetism in strongly correlated systems. (Source: Lattes Curriculum)
- Quasilocal conserved quantities and transport in integrable one-dimensional systems, AV.EXT
Abstract
Quantum integrable models are usually characterized by a macroscopic number of local conserved quantities. One example is the XXZ model, which describes anisotropic spin-$1/2$ chain materials and Mott-insulating phases of two-component bosons in optical lattices. The nontrivial conservation laws of integrable systems have striking consequences for their dynamical properties. Recently, i...
- Dynamics of two-body operators in exactly solvable spin chains, BP.IC
Abstract
Quantum spin-1/2 chains exhibit exotic phenomena such as absence of magnetic order at zero temperature and spectrum with fractional excitations. The interpretation of experiments that probe the excitation spectrum, such as resonant inelastic x-ray scattering (RIXS), requires the calculation of dynamical correlation functions at finite energies, a challenge for conventional analytical me...
- Spin liquids and strongly correlated topological insulators, BP.DD
Abstract
Spin liquids and topological insulators are examples of phases described by a nontrivial ground state without spontaneous symmetry breaking. Recent theoretical and experimental results have raised interest in strongly correlated topological phases. An interesting possibility is that topological Mott insulators represent a route to discover new kinds of spin liquids. In this project we p...
- Introduction to edge states in insulators, BP.IC
Abstract
Localized surface states account for nontrivial transport properties in some insulating phases of electron systems. Examples include the quantum Hall effect and topological insulators. In this project, we propose a theoretical study of edge states that show up in noninteracting lattice models in one and two dimensions, such as the Su-Schrieffer-Heeger model for polyacetylene and the mod...

- Topological phases in spin-orbit-coupled strongly correlated systems, BE.EP.DD
Abstract
Quantum spin liquids are systems of interacting spins that remain disordered at zero temperature due to strong quantum fluctuations. Such systems are characterized by an exotic excitation spectrum with deconfined fractional quasiparticles and emergent gauge fields. The goal of this PhD project is to study a theoretical model for Mott-insulating double perovskites with strong spin-orbit ...
