Description

Two-dimension van-der-Waals materials provide a versatile platform with a high degree of tunability, that has led to a multitude of realizations of correlated and topological phases in the recent years. However, theoretical modeling remains a challenge: Strong correlations call for tools beyond mean-field theory. In this talk I will explain how variational Monte Carlo, in particular neural quantum states, addresses this challenge. I will use these tools to piece together features such as anisotropy or quantum geometry in 2D quantum materials and explain their effect on the emerging phases. I will then explain how modern machine learning advances can be used to shape new tools for the exploration of strongly correlated materials.
