Bounds on adiabatic path geometry from the width class of the gap profile
Mancheon Han, Sangkook Choi
In an adiabatic evolution, the wave function follows the path of ground states of a Hamiltonian as is tuned from to . The geometry of this adiaba…

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…
