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…
Chiral spin liquid phase in an optical lattice at mean-field level
Jian Yang, Xiong-Jun Liu
We study an optical Raman square lattice with synthetic gauge flux to show chiral spin liquid (CSL) phase for cold atoms based on slave-rotor theory and spinon mean…
Anomalous second-order skin modes in Floquet non-Hermitian systems
Chun-Hui Liu, Haiping Hu, Shu Chen +1
The non-Hermitian skin effect under open boundary conditions is widely believed to originate from the intrinsic spectral topology under periodic boundary conditions. If the eigensp…
Symmetric non-Hermitian skin effect with emergent nonlocal correspondence
Zhi-Yuan Wang, Jian-Song Hong, Xiong-Jun Liu
The non-Hermitian skin effect (NHSE) refers to that an extensive number of eigenstates of a non-Hermitian system are localized in open boundaries. Here we predict a universal pheno…
Fractional quantum anomalous Hall phase for Raman superarray of Rydberg atoms
Ting-Fung Jeffrey Poon, Xin-Chi Zhou, Bao-Zong Wang +2
Rydberg atom arrays offer promising platforms for quantum simulation of correlated quantum matter and raise great interests. This work proposes a novel stripe-lattice model with Ra…
