Discrete power-law decay of subsystem distance after a quantum quench
Bin Sui, Jiaju Zhang
The paper numerically investigates the decay of the Bures distance between a subsystem’s reduced density matrix and its stationary generalized Gibbs ensemble after a global quench…

Subsystem fidelity in two-dimensional conformal field theories
Bin Sui, Yihao Wang, Jiaju Zhang
We investigate the short-interval expansion of the subsystem fidelity in two-dimensional conformal field theories (2D CFTs) using the operator product expansion (OPE) of twist oper…
