Identifying slow relaxation in many-body quantum systems through state-graph geometry and state-graph heterogeneity
Heiko Georg Menzler, Tom Ben-Ami
We adapt tools from the theory of quantum random walks to investigate slow relaxation dynamics through the many-body state graph. Specifically, we construct a probe of heterogeneit…

Floquet Many-Body Cages
Tom Ben-Ami, Roderich Moessner, Markus Heyl
Many-body cages have very recently emerged as a general route for nonergodic behaviour in quantum matter. Here, we show that new types of many-body cages can be engineered in Floqu…

Many-body cages: disorder-free glassiness from flat bands in Fock space, and many-body Rabi oscillations
Tom Ben-Ami, Markus Heyl, Roderich Moessner
We introduce many-body caging as a novel mechanism for nonthermal behaviour in quantum matter. We define many-body cages as eigenstates that, through quantum interference, become l…
