Expansion of one-dimensional lattice hard-core bosons at finite temperature
Wei Xu, Marcos Rigol
We develop an exact approach to study the quench dynamics of hard-core bosons initially in thermal equilibrium in one-dimensional lattices. This approach is used to study the sudde…
La-doping effect on spin-orbit coupled Sr2IrO4 probed by x-ray absorption spectroscopy
Jie Cheng, Xuanyong Sun, Shengli Liu +5
Sr2IrO4 was predicted to be an unconventional superconductor upon carrier doping since it highly resembles the high-temperature cuprates. Here, to understand carrier doping effect…
A critical point in Sr2-xIrO4 and less distorted IrO6 octahedra induced by deep Sr-vacancies
Jie Cheng, Shengli Liu, Bin Li +3
For the Sr2-xIrO4 system, recent work pointed out the abnormal electronic and magnetic properties around the critical point. Here, to understand Sr-vacancy effect on spin-orbit cou…
Universal entropy relations: entropy formulae and entropy bound
Hang Liu, Xin-he Meng, Wei Xu +1
We survey the applications of universal entropy relations in black holes with multi-horizons. In sharp distinction to conventional entropy product, the entropy relationship here no…
Multiband Effects and the Bose-Hubbard Model in One-Dimensional Lattices
Wei Xu, Maxim Olshanii, Marcos Rigol
We study phase diagrams of one-dimensional bosons with contact interactions in the presence of a lattice. We use the worm algorithm in continuous space and focus on the incommensur…
Asymptotic results for exponential functionals of Levy processes
Zenghu Li, Wei Xu
In this work we give a complete description to the asymptotic behaviors of exponential functionals of Lévy processes and divide them into five different types according to their co…
