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…

Negativity spectrum of one-dimensional conformal field theories
Paola Ruggiero, Vincenzo Alba, Pasquale Calabrese
The partial transpose of the reduced density matrix is the key object to quantify the entanglement in mixed states, in particular through the presence of negative…

The entanglement negativity in random spin chains
Paola Ruggiero, Vincenzo Alba, Pasquale Calabrese
We investigate the logarithmic negativity in strongly-disordered spin chains in the random-singlet phase. We focus on the spin-1/2 random Heisenberg chain and the random XX chain.…
