Born-rule statistical dynamical quantum phase transitions under measurement
Guan-Hua Chen, Guo-Yi Zhu
Dynamical quantum phase transitions (DQPTs) occur at times when a quantum state exhibits a nonanalytic change in its return probability. This can be viewed as the probability of co…
Directing entanglement spreading by means of a quantum East/West heterojunction structure
Guanhua Chen, Yao Yao
We extend the translationally invariant quantum East model to an inhomogeneous chain with East/West heterojunction structure. In analogy to the quantum diffusion of substantial par…
Long-coherence pairing of low-mass conduction electrons in copper-substituted lead apatite
Jicheng Liu, Chenao He, Yin-Hui Peng +7
Two entangled qubits emerge as an essential resource for quantum control, which are normally quantum confined with atomic precision. It seems inhibitive that in the macroscopic sco…
Nonthermal entanglement dynamics in a dipole-facilitated glassy model with disconnected subspaces
Guanhua Chen, Yao Yao
We construct a dipole-facilitated kinetic constraint to partition the Hilbert space into three disconnected subspaces, two of which are nonthermal and the other acts as an intrinsi…
Dynamics of entangled domain walls in quantum many-body scars and breakdown of their prethermalization
Guanhua Chen, Weijie Huang, Yao Yao
Based on the PXP model adapted for Rydberg-blockaded chains, we investigate dynamics of topological domain walls between different quantum many-body scar states of s…
Time-dependent density-functional theory for open systems
Xiao Zheng, Fan Wang, Chi Yung Yam +2
By introducing the self-energy density functionals for the dissipative interactions between the reduced system and its environment, we develop a time-dependent density-functional t…
