Self-consistent vertex corrected with static and dynamic screening using tensor hypercontraction: assessment of molecular charged excitations
Munkhorgil Wang, Ming Wen, Pavel Pokhilko +3
We investigate self-consistent vertex corrections to the self-energy for ionization potentials (IPs) and electron affinities (EAs). We benchmark IPs against CCSD(T) refere…
Hybrid Hamiltonian-diagrammatic quantum impurity solver
Yang Yu, Gaurav Harsha, Lei Zhang +4
Quantum impurity models, which describe the coupling between interacting orbitals and a non-interacting bath, play a central role in the physics of strongly correlated electron sys…
All-Electron Relativistic Fully Self-Consistent Study of Heteronuclear Actinide-Containing Diatomics
Jacob Adamski, Vibin Abraham, Dominika Zgid
The fully self-consistent (sc) approximation provides a Green's-function approach that is starting-point independent and offers a favorable cost-to-accuracy balance compar…
Dynamically Corrected Bethe-Salpeter Equation Solver for Self-consistent Reference on the Matsubara Frequency Axis
Ming Wen, Gaurav Harsha, Dominika Zgid
We present a Bethe-Salpeter equation (BSE) solver based on a self-consistent reference evaluated on the Matsubara frequency axis, referred to as BSE@sc. The self-consisten…
Evolution of the Saddle Point in Antimony Telluride Homologous Superlattices
Yi-Hsin Shen, Shane Smolenski, Ming Wen +13
Combining topological insulators with topological semimetals in the form of homologous superlattices is a promising approach for generating correlated quantum matter based upon Fer…
Low Depth Unitary Coupled Cluster Algorithm for Large Chemical Systems
Jeremy Canfield, Dominika Zgid, J K Freericks
The unitary coupled cluster (UCC) algorithm is one of the most promising implementations of the variational quantum eigensolver for quantum computers. However, for large systems, t…
