Entanglement hamiltonian and entanglement contour in inhomogeneous 1D critical systems
Erik Tonni, Javier Rodríguez-Laguna, Germán Sierra
Inhomogeneous quantum critical systems in one spatial dimension have been studied by using conformal field theory in static curved backgrounds. Two interesting examples are the fre…
Corner contributions to holographic entanglement entropy in AdS4/BCFT3
Domenico Seminara, Jacopo Sisti, Erik Tonni
We study the holographic entanglement entropy of spatial regions with corners in the AdS4/BCFT3 correspondence by considering three dimensional boundary conformal field theories wh…
Entanglement spectrum degeneracy and Cardy formula in 1+1 dimensional conformal field theories
Vincenzo Alba, Pasquale Calabrese, Erik Tonni
We investigate the effect of a global degeneracy in the distribution of entanglement spectrum in conformal field theories in one spatial dimension. We relate the recently found uni…
A contour for the entanglement entropies in harmonic lattices
Andrea Coser, Cristiano De Nobili, Erik Tonni
We construct a contour function for the entanglement entropies in generic harmonic lattices. In one spatial dimension, numerical analysis are performed by considering harmonic chai…
