Dataset description

This dataset contains the numerical simulation data underlying all main-text and Supplemental Material figures of the paper "Tunable quantum Mpemba effect in long-range interacting systems". The data comprise quantum many-body dynamics simulations of a one-dimensional long-range interacting spin-1/2 XYZ/XXZ spin chain, obtained using the time-dependent variational principle (TDVP) for both finite and translation-invariant infinite matrix product states (MPS/iMPS), together with ground-state density matrix renormalization group (DMRG) calculations. The data include entanglement entropies, entanglement asymmetry, trace distance, order-parameter dynamics, and Mpemba-time/critical-interaction-range data used to characterize the quantum Mpemba effect and its interplay with spontaneous symmetry breaking as a function of interaction range, magnetic field strength, and initial-state energy density. Full details of the models, methods, and definitions are given in the accompanying publication and its Supplemental Material.
