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…
