Quantum-embedding description of the Anderson lattice model with the ghost Gutzwiller Approximation

Marius S. Frank, Tsung-Han Lee, Gargee Bhattacharyya +5

We present benchmark calculations of the Anderson lattice model based on the recently-developed "ghost Gutzwiller approximation". Our analysis shows that, in some parameters regime…

Bypassing the computational bottleneck of quantum-embedding theories for strong electron correlations with machine learning

John Rogers, Tsung-Han Lee, Sahar Pakdel +5

A cardinal obstacle to performing quantum-mechanical simulations of strongly-correlated matter is that, with the theoretical tools presently available, sufficiently-accurate comput…
