Entropy slowdown to a prethermal plateau via interaction-range–quench interplay

Investigate whether tuning the interaction-range exponent α together with quench strength can slow entropy growth entirely into a prethermal plateau in long-range interacting quantum systems, and determine the conditions under which such a plateau emerges.

Background

By varying quench strengths and interaction ranges, the authors observe significant modifications in entropy dynamics, including initial quadratic growth and slower relaxation for very long-range interactions (α<1).

On this basis, they propose a conjecture that the right combination of interaction range and quench parameters could fully slow entropy growth into a prethermal plateau, pointing to an explicit, testable scenario in related systems.
