Quantum Rényi-Jarzynski Equality
Benjamin Bobell, Mert Okyay, Rahul Nandkishore
The Jarzynski equality provides a strict link between nonequilibrium work and equilibrium free energy changes. Its typical quantum formulations, however, rely on measurement protoc…
Strong Hilbert space fragmentation and fractons from subsystem and higher-form symmetries
Charles Stahl, Oliver Hart, Alexey Khudorozhkov +1
We introduce a new route to Hilbert space fragmentation in high dimensions leveraging the group-word formalism. We show that taking strongly fragmented models in one dimension and…
Towards absolutely stable ergodicity breaking in two and three dimensions
Charles Stahl, Oliver Hart, Rahul Nandkishore
We propose new physically reasonable systems capable of avoiding ergodicity at infinite time in the thermodynamic limit, even with generic perturbations and when coupled to a heat…
Robust Hilbert space fragmentation in group-valued loop models
Alexey Khudorozhkov, Charles Stahl, Oliver Hart +1
We introduce a large class of models exhibiting robust ergodicity breaking in quantum dynamics. Our work is inspired by recent discussions of "topologically robust Hilbert space fr…
