Three complementary diagnostics reveal how disorder creates glassy behavior in ultracold atoms while thermal fluctuations progressively erase these signatures, showing why single measures cannot fully characterize the Bose-glass state.

Studied non-equilibrium dynamics of ultracold bosons during quantum quenches across the superfluid-Bose glass transition. Observed distinct behaviors: momentum-space quantum walks in disordered regime, real-space light-cone spreading in superfluid regime.
