Dynamic structure factor of a spin-1/2 Heisenberg chain with long-range interactions
Sibin Yang, Gabe Schumm, Anders W. Sandvik
We study the dynamic structure factor of the spin-1/2 chain with long-range, power-law decaying unfrustrated (sign alternating) Heisenberg interactions $J_r \sim (-1)^{r-1…

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…
