Notes on the Cluster Gutzwiller Method: Inhomogeneous Lattices, Excitations, and Cluster Time Evolution

TL;DR

This paper discusses the cluster Gutzwiller method's versatility in handling large inhomogeneous lattices, local excitations, and dynamic evolution of correlated quantum systems, highlighting its broad applicability.

Contribution

It demonstrates that the cluster Gutzwiller method can be effectively applied to large inhomogeneous systems, local excitations, and time-dependent phenomena in quantum lattice models.

Findings

Applicable to large inhomogeneous lattices

Capable of computing local excitations

Suitable for cluster time evolution

Abstract

Several perspectives of the cluster Gutzwiller method are briefly discussed. I show that the cluster mean-field method can be used for large inhomogeneous lattices, for computing local excitations, and for the time evolution of correlated quantum systems.
