Abstract

This SPRINT project aims to bring together researchers from the University of São Paulo (USP) and the University of Rochester (USA) to study transport phenomena in strongly correlated and dissipative (open) quantum systems. In this context, non-Hermitian Hamiltonians emerge as a powerful tool for describing dissipative processes and non-equilibrium steady states (NESS) in these systems. The project involves developing Density Matrix Renormalization Group (DMRG) and Matrix Product States (MPS) techniques to solve Lindblad master equations governing open quantum systems. Through close collaboration between researchers from both institutions, the project aims to create and refine numerical tools for simulating quantum transport under dissipative conditions. The expected outcomes include publicly available computational codes, scientific publications, and contributions to the training of students and researchers in the field of quantum many-body physics.
