Observation of Strong Electron Correlation in Planetary Atomic Structure
Xinglong Yu, Yongyan Han, Zhenjie Shen +10
Unravelling two-electron correlation is a long-standing challenge at the heart of few-body quantum physics, underlying correlated phenomena across atomic, molecular and condensed-m…
Emergent synchronization mode in coupled Rydberg atomic chains
Weilun Jiang
We report a new oscillatory form in the two coupled dissipative Rydberg atomic chains by modulating its spacing. Such oscillation has -phase difference between two neighboring…
Discrete time quasi-crystal in Rydberg atomic chain
Xiaofan Luo, Yaoting Zhou, Zhongxiao Xu +1
Discrete time quasi-crystals are non-equilibrium quantum phenomena with quasi-periodic order in the time dimension, and are an extension of the discrete time-crystal phase. As a na…
High-efficiency quantum Monte Carlo algorithm for extracting entanglement entropy in interacting fermion systems
Weilun Jiang, Gaopei Pan, Zhe Wang +3
The entanglement entropy probing novel phases and phase transitions numerically via quantum Monte Carlo has made great achievements in large-scale interacting spin/boson systems. I…
Identifying two-dimensional topological phase transition by entanglement spectrum : A fermion Monte Carlo study
Weilun Jiang, Xiaofan Luo, Bin-Bin Mao +1
Among many types of quantum entanglement properties, the entanglement spectrum provides more abundant information than other observables. Exact diagonalization and density matrix r…
