  • We find that, in the quantum transition of Ising spin glass, the closing of the gap at the critical point can remain algebraic by restricting the symmetry of possible excitations, which is crucial for quantum annealing.

  • While temperature chaos is an equilibrium notion that denotes the extreme fragility of the glassy phase with respect to temperature changes, it remains unclear whether it is present in non-equilibrium dynamics. Here the authors use the Janus II supercomputer to prove the existence of dynamic temperature chaos, a nonequilibrium phenomenon that closely mimics equilibrium temperature chaos.
