Global Quenches after Localised Perturbations
read the original abstract
We investigate the effect of a single spin flip preceding a global quench between translationally invariant local Hamiltonians in spin-$\tfrac{1}{2}$ chains. The effect of the localised perturbation does not fade away however large the distance from the perturbation is. In particular, translational invariance is not restored and the infinite time limit depends on whether the spin was flipped or not. We argue that this phenomenon is more general than the particular example considered and we conjecture that it is triggered by topological properties, specifically, the existence of "semilocal charges".

Temperature Beyond Equilibrium in Isolated Quantum Many-Body Systems and Their Subsystems
A nonequilibrium temperature is defined as the coordinate of a canonical pseudolocal flow on leaves of fixed energy coherence in the state space of isolated quantum spin chains.
