Subsystem trace distance in low-lying states of (1 + 1)-dimensional conformal field theories
Abstract We report on a systematic replica approach to calculate the subsystem trace distance for a quantum field theory. This method has been recently introduced in [J. Zhang, P. Ruggiero and P. Calabrese, Phys. Rev. Lett. 122 (2019) 141602 ], of which this work is a completion. The trace distance...
