Negativity spectrum in 1D gapped phases of matter
Glen Bigan Mbeng, Vincenzo Alba, Pasquale Calabrese
We investigate the spectrum of the partial transpose (negativity spectrum) of two adjacent regions in gapped one-dimensional models. We show that, in the limit of large regions, th…
Out-of-equilibrium protocol for Rényi entropies via the Jarzynski equality
Vincenzo Alba
In recent years entanglement measures, such as the von Neumann and the Rényi entropies, provided a unique opportunity to access elusive feature of quantum many-body systems. Howeve…
Entanglement and thermodynamics after a quantum quench in integrable systems
Vincenzo Alba, Pasquale Calabrese
Entanglement and entropy are key concepts standing at the foundations of quantum and statistical mechanics, respectively. In the last decade the study of quantum quenches revealed…
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.…
