Determination of dynamical quantum phase transition for boson systems using the Loschmidt cumulants method
Pengju Zhao, Jingxin Sun, Shengjie Jin +4
We study the dynamical quantum phase transition(DQPT) of the Bose-Hubbard model utilizing recently developed Loschmidt cumulants method. We determine the complex Loschmidt zeros of…

Observation of 2D Mott insulator and -superfluid quantum phase transition in shaking optical lattice
Jingxin Sun, Pengju Zhao, Zhongshu Hu +4
The Mott insulator and superfluid phase transition is one of the most prominent phenomena in ultracold atoms. In this work, we report the observation of a novel 2D quantum phase tr…
