Saddles-to-minima topological crossover and glassiness in the Rubik's Cube
Alex Gower, Oliver Hart, Claudio Castelnovo
Slow relaxation and glassiness have been the focus of extensive research attention, along with popular and technological interest, for many decades. While much understanding has be…
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…
Playing nonlocal games across a topological phase transition on a quantum computer
Oliver Hart, David T. Stephen, Dominic J. Williamson +2
Many-body quantum games provide a natural perspective on phases of matter in quantum hardware, crisply relating the quantum correlations inherent in phases of matter to the securin…
