The authors present an insightful study on the quench dynamics in weakly interacting two-dimensional bosonic systems, focusing on the dynamics of entanglement entropy, asymmetry, and quantum fidelity. In particular, they demonstrate the presence of the recently discovered quantum Mpemba effect, derive the microscopic conditions necessary for this effect to occur, and show that these conditions are never met in the Bogoliubov theory.
