Abstract

The simulation of materials exhibiting strong electronic correlations presents a major challenge for classical computing, which has lead to the development of numerous methods. Among these, Dynamical Mean-Field Theory (DMFT) has enjoyed widespread success since its introduction. The method consists in approximating a complex lattice problem with an impurity problem, the parameters of which are determined through a self-consistent loop. While solving this model remains difficult, the recent emergence of solvers based on an auxiliary representation of the model as an open system (i.e., subject to noise due to interactions with an environment) offers a promising avenue. This thesis aims at exploring this path, particularly in conjunction with the use of quantum computers, which appear to be the natural platform for simulating such models.
