Dataset for "Role reversal in quantum Mpemba effect"

The data files "U1_v.dat" and "U2_v.dat" contain the elements of the local unitary operators (matrices) denoted by U_{A} and U_{B}, respectively, for the numerical analysis regarding the entanglement, in the main article. The data files "rho0_v.dat" and "rhop0_v.dat" contain the elements of the initial pure states (density matrices) denoted by \rho_{0} and \rho'_{0}, respectively, for the numerical analysis regarding the trace distance, in the main article. In all four files, the matrix elements are stored in vectorized form using column stacking, i.e., the matrix columns are arranged sequentially into a single vector from top to bottom and from left to right.
