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…
Comment on: "Dynamics of disordered quantum systems with two- and three-dimensional tensor networks" arXiv:2503.05693
Andrew D. King, Alberto Nocera, Marek M. Rams +8
In a recent preprint [1] (arXiv:2503.05693), Tindall et al. presented impressive classical simulations of quantum dynamics using tensor networks. Their methods represent a signific…
Using operator covariance to disentangle scaling dimensions in lattice models
Anders W. Sandvik
In critical lattice models, distance () dependent correlation functions contain power laws governed by scaling dimensions of an underlying continuum field theory.…
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…
