Energy-space quantum walks separate classical population equilibration to Gibbs statistics from persistent quantum coherence that prevents full state convergence to the thermal manifold.
Exact closed-form size-independent expressions for von Neumann and Rényi entanglement entropies plus Loschmidt echoes are obtained for quench dynamics in the staggered XXZ antiferromagnetic chain in the flat-band limit, validated by IBM-Q simulations.
Quench-induced collective excitations in trapped 2D BECs show hydrodynamic behavior at low energies due to broken scale invariance and acoustic modes at high energies.
