Localized Fock Space Cages in Kinetically Constrained Models
Cheryne Jonay, Frank Pollmann
We investigate a mechanism for non-ergodic behavior in many-body quantum systems arising from destructive interference, leading to localization in Fock space. Drawing parallels wit…

Two-stage relaxation of operators through domain wall and magnon dynamics
Cheryne Jonay, Cathy Li, Tianci Zhou
The out-of-time ordered correlator (OTOC) has become a popular probe for quantum information spreading and thermalization. In systems with local interactions, the OTOC defines a ch…
