GEM: An implementation of the ghost-Gutzwiller approximation for simulating interacting quantum systems
Samuele Giuli, Tsung-Han Lee, Yong-Xin Yao +6
We present GEM (Ghost Embedding Method), an open-source software package written in Python for computing equilibrium properties of strongly correlated electronic systems within the…
Universal Signature of Hundness and Its Quantification
Dongwook Kim, Ina Park, Bo Gyu Jang +1
Hund's coupling induces fundamentally different correlation effects from Hubbard . This leads to a violation of the Brinkman--Rice scenario and the emergence of a Janus-face…
Neural-Network Quantum Embedding Solvers for Correlated Materials
Agnes Valenti, Ina Park, Antoine Georges +2
Quantum impurity solvers are the computational bottleneck of quantum embedding approaches to correlated materials, such as dynamical mean-field theory (DMFT). We show that neural n…
Impact of strong electronic correlations on altermagnets: the case of NiS2
Ina Park, Turan Birol, Antoine Georges +1
One of the distinguishing features of an altermagnet is that its spin-up and spin-down bands display a nodal momentum-dependent splitting even in the absence of spin-orbit coupling…
Clean realization of the Hund physics near the Mott transition: under pressure
Ina Park, Bo Gyu Jang, Dong Wook Kim +2
Strong correlation effects caused by Hund's coupling have been actively studied during the past decade. Hund's metal, strongly correlated while far from the Mott insulating limit,…
