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…

Denoising of Imaginary Time Response Functions with Hankel projections
Yang Yu, Alexander F. Kemper, Chao Yang +1
Imaginary-time response functions of finite-temperature quantum systems are often obtained with methods that exhibit stochastic or systematic errors. Reducing these errors comes at…

Denoising and Extension of Response Functions in the Time Domain
Alexander F. Kemper, Chao Yang, Emanuel Gull
Response functions of quantum systems, such as electron Green's functions, magnetic, or charge susceptibilities, describe the response of a system to an external perturbation. They…
