Imaginary-time correlations in time-sliced stochastic series expansion
Ryan Flynn, Adam Iaizzi, Sibin Yang +2
Combined with numerical analytic continuation techniques, quantum Monte Carlo (QMC) methods enable the extraction of real-frequency dynamical properties from imaginary-time correla…
Single-hole spectral functions in one-dimensional quantum magnets with different ground states
Sibin Yang, Gabe Schumm, Bowen Zhao +1
Recent advances in numerical analytic continuation with physics-motivated constraints allow sharp spectral features to be extracted from imaginary-time quantum Monte Carlo (QMC) da…
Single-Particle Dispersion and Density of States of the Half-Filled 2D Hubbard Model
Gabe Schumm, Shiwei Zhang, Anders W. Sandvik
Implementing an improved method for analytic continuation and working with imaginary-time correlation functions computed using quantum Monte Carlo simulations, we resolve the singl…
Cross Validation in Stochastic Analytic Continuation
Gabe Schumm, Sibin Yang, Anders W. Sandvik
Stochastic Analytic Continuation (SAC) of Quantum Monte Carlo (QMC) imaginary-time correlation function data is a valuable tool in connecting many-body models to experimentally mea…
