Lattice Bisognano-Wichmann modular Hamiltonian in critical quantum spin chains
Jiaju Zhang, Pasquale Calabrese, Marcello Dalmonte +1
We carry out a comprehensive comparison between the exact modular Hamiltonian and the lattice version of the Bisognano-Wichmann (BW) one in one-dimensional critical quantum spin ch…
Rényi entropy and subsystem distances in finite size and thermal states in critical XY chains
Raúl Arias, Jiaju Zhang
We study the Rényi entropy and subsystem distances on one interval for the finite size and thermal states in the critical XY chains, focusing on the critical Ising chain and XX cha…
Roadmap on Wilson loops in 3d Chern-Simons-matter theories
Nadav Drukker, Diego Trancanelli, Lorenzo Bianchi +18
This is a compact review of recent results on supersymmetric Wilson loops in ABJ(M) and related theories. It aims to be a quick introduction to the state of the art in the field an…
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…
Rényi entropy at large energy density in 2D CFT
Wu-zhong Guo, Feng-Li Lin, Jiaju Zhang
We investigate the Rényi entropy and entanglement entropy of an interval with an arbitrary length in the canonical ensemble, microcanonical ensemble and primary excited states at l…
