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…

Global approximations to correlation functions of strongly interacting quantum field theories
Yuanran Zhu, Yang Yu, Efekan Kökcü +2
We introduce a method for constructing global approximations to correlation functions of strongly interacting quantum field theories, starting from perturbative results. The key id…

Minimal pole representation for spectral functions
Lei Zhang, André Erpenbeck, Yang Yu +1
Representing spectral densities, real-frequency, and real-time Green's functions of continuous systems by a small discrete set of complex poles is an ubiquitous problem in condense…
