Dynamical Variational Monte Carlo as a quantum impurity solver*

The theoretical and numerical treatment of strongly-correlated many electron systems remains an outstanding challenge of modern condensed matter physics. The recently developed dynamical Variational Monte Carlo (dVMC) method enables the computation of the Green's function for larger clusters, but has so far been limited to translationally invariant models with periodic boundary conditions. Here we propose a method to relax these constraints. This new approach makes it possible to use dVMC as a quantum impurity solver for embedding techniques such as Cluster dynamical mean field theory (CDMFT).
