Discrete power-law decay of subsystem distance after a quantum quench
Bin Sui, Jiaju Zhang
We present a numerical study of subsystem distance decay following a global quantum quench in the infinite one-dimensional transverse-field Ising chain, using the mathematically ri…

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…
