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…
