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…

SU() Quantum Spin Model with Weak and Strong First-Order Néel to Valence-Bond Solid Transitions
Ryan Flynn, Anders W. Sandvik
We introduce an SU() symmetric two-dimensional quantum spin model, the X-Q model, which hosts a ground state transition between Néel antiferromagnetic and spontaneously dimerize…
