Disordered Lieb-Robinson bounds in one dimension
Christopher L. Baldwin, Adam Ehrenberg, Andrew Y. Guo +1
By tightening the conventional Lieb-Robinson bounds to better handle systems which lack translation invariance, we determine the extent to which "weak links" suppress operator grow…
Infinite-randomness criticality in monitored quantum dynamics with static disorder
Aidan Zabalo, Justin H. Wilson, Michael J. Gullans +4
We consider a model of monitored quantum dynamics with quenched spatial randomness: specifically, random quantum circuits with spatially varying measurement rates. These circuits u…
Path sampling of recurrent neural networks by incorporating known physics
Sun-Ting Tsai, Eric Fields, Yijia Xu +2
Recurrent neural networks have seen widespread use in modeling dynamical systems in varied domains such as weather prediction, text prediction and several others. Often one wishes…
Localization crossover and subdiffusive transport in a classical facilitated network model of a disordered, interacting quantum spin chain
Kai Klocke, Christopher David White, Michael Buchhold
We consider the random-field Heisenberg model, a paradigmatic model for many-body localization (MBL), and add a Markovian dephasing bath coupled to the Anderson orbitals of the mod…
Operator scaling dimensions and multifractality at measurement-induced transitions
Aidan Zabalo, Michael J. Gullans, Justin H. Wilson +5
Repeated local measurements of quantum many body systems can induce a phase transition in their entanglement structure. These measurement-induced phase transitions (MIPTs) have bee…
Extended nonergodic regime and spin subdiffusion in disordered SU(2)-symmetric Floquet systems
Zhi-Cheng Yang, Stuart Nicholls, Meng Cheng
We explore thermalization and quantum dynamics in a one-dimensional disordered SU(2)-symmetric Floquet model, where a many-body localized phase is prohibited by the non-abelian sym…
