Local-to-Global Entanglement Dynamics by Periodically Driving Impurities
Zhi-Xing Lin, Abhinav Prem, Shinsei Ryu +1
We study the entanglement dynamics of one-dimensional fermionic chains subject to a local Floquet drive of a two-site impurity, and uncover a sharp transition in the entanglement d…

Entanglement transitions in structured and random nonunitary Gaussian circuits
Bastien Lapierre, Liang-Hong Mo, Shinsei Ryu
We study measurement-induced phase transitions in quantum circuits consisting of kicked Ising models with postselected weak measurements, whose dynamics can be mapped onto a classi…
