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…
H-NESSi: The Hierarchical Non-Equilibrium Systems Simulation package
Thomas Blommel, Jeremija Kovačević, Jason Kaye +3
We present H-NESSi (The Hierarchical Non-Equilibrium Systems Simulation package), an open-source software package for solving the Kadanoff-Baym equations (KBE) of nonequilibrium Gr…
Multi-orbital dynamical mean-field theory with a complex-time solver
Yang Yu, Lei Zhang, Emanuel Gull +2
We present the combination of a complex-time tensor-network impurity solver with an analytic continuation scheme based on exponential fitting as an efficient framework for single a…
Symmetry-resolved topology from interacting Green's functions
Gaurav Harsha, Selina Dirnböck, Emanuel Gull +3
Topological phases in narrow-gap materials often arise from a delicate interplay of spin-orbit coupling (SOC) and electron correlation, making their prediction sensitive to the und…
