Subsystem trace distance in low-lying states of -dimensional conformal field theories
Jiaju Zhang, Paola Ruggiero, Pasquale Calabrese
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,…
Subsystem Trace Distance in Quantum Field Theory
Jiaju Zhang, Paola Ruggiero, Pasquale Calabrese
We develop a systematic method to calculate the trace distance between two reduced density matrices in 1+1 dimensional quantum field theories. The approach exploits the path integr…
Relative Entanglement Entropies in 1+1-dimensional conformal field theories
Paola Ruggiero, Pasquale Calabrese
We study the relative entanglement entropies of one interval between excited states of a 1+1 dimensional conformal field theory (CFT). To compute the relative entropy $S(ρ_1 \| ρ_0…
