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…

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…
