Finite Temperature Minimal Entangled Typical Thermal States Impurity Solver
Xiaodong Cao, E. Miles Stoudenmire, Olivier Parcollet
We present a minimally entangled typical thermal state (METTS) quantum impurity solver for general multi-orbital systems at finite temperatures. We introduce an improved estimator…

Dynamical correlation functions from complex time evolution
Xiaodong Cao, Yi Lu, E. Miles Stoudenmire +1
We present an approach to tame the growth of entanglement during time evolution by tensor network methods. It combines time evolution in the complex plane with a perturbative and c…
