Parameter-free analytic continuation for quantum many-body calculations
Mancheon Han, Hyoung Joon Choi
We develop a reliable parameter-free analytic continuation method for quantum many-body calculations. Our method is based on a kernel grid, a causal spline, a regularization using…

Causal optimization method for imaginary-time Green's functions in interacting electron systems
Mancheon Han, Hyoung Joon Choi
We develop a causal optimization method that ensures causality in numerical calculations of Green's functions in interacting electron systems. Our method removes noncausality of nu…
