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…
Spinons and Spin-Charge Separation at the Deconfined Quantum Critical Point
Sibin Yang, Anders W. Sandvik
Using quantum Monte Carlo and numerical analytic continuation methods, we study the dynamic spin structure factor and the single-hole spectral function of a two-dimensional quantum…
Decoherence in high energy collisions as renormalization group flow
Jiayin Gu, Shi-Jia Lin, Ding Yu Shao +2
The unification of quantum information science and collider physics is opening a new frontier in high-energy experiments, making a systematic understanding of decoherence a critica…
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-…
