| 11:00 - 12:00 Theory weekly seminar (TWS) Symmetry-Resolved Entanglement Entropy for Chared Thermofield Double States School PARTICLES AND ACCELERATORS Abstract: We explore the time evolution of symmetry-resolved entanglement entropy (SREE) for the thermofield double (TFD) states of complex scalar quantum field theories. Through the covariance matrix approach, we find a mechanism to describe the symmetry-resolved entanglement dynamics in non-equilibrium systems. This dynamical behavior obeys the quasi-particle picture which is universal for integrable systems. We find the pattern of time evolution as follows: for the SREE and confrontational entropy SC, linear growth is followed by saturation. On a circular lattice, for long times we see oscillatory behavior due to the ... |
