Entanglement dynamics after quantum quenches in generic integrable systems

- V. Alba, P. Calabrese
- Physics
- 20 December 2017

The time evolution of the entanglement entropy in non-equilibrium quantum systems provides crucial information about the structure of the time-dependent state. For quantum quench protocols, by… Expand

Entanglement entropy of excited states

- V. Alba, M. Fagotti, P. Calabrese
- Physics
- 10 September 2009

We study the entanglement entropy of a block of contiguous spins in excited states of spin chains. We consider the XY model in a transverse field and the XXZ Heisenberg spin chain. For the latter, we… Expand

Quantum information dynamics in multipartite integrable systems

- V. Alba, P. Calabrese
- PhysicsEPL (Europhysics Letters)
- 24 September 2018

In a non-equilibrium many-body system, the quantum information dynamics between non-complementary regions is a crucial feature to understand the local relaxation towards statistical ensembles.… Expand

Eigenstate thermalization hypothesis and integrability in quantum spin chains

- V. Alba
- Physics
- 22 September 2014

We investigate the eigenstate thermalization hypothesis (ETH) in integrable models, focusing on the spin-1/2 isotropic Heisenberg (XXX) chain. We provide numerical evidence that ETH holds for typical… Expand

Bound states and entanglement in the excited states of quantum spin chains

- Jan Molter, T. Barthel, U. Schollwock, V. Alba
- Physics
- 30 June 2014

We investigate entanglement properties of the excited states of the spin-1/2 Heisenberg (XXX) chain with isotropic antiferromagnetic interactions, by exploiting the Bethe ansatz solution of the… Expand

Entanglement negativity and conformal field theory: a Monte Carlo study

- V. Alba
- Physics
- 5 February 2013

We investigate the behavior of the moments of the partially transposed reduced density matrix in critical quantum spin chains. Given subsystem A as the union of two blocks, this is the (matrix)… Expand

Entanglement spectrum of the Heisenberg XXZ chain near the ferromagnetic point

- V. Alba, M. Haque, A. Laeuchli
- Physics
- 1 June 2012

We study the entanglement spectrum (ES) of a finite XXZ spin 1/2 chain in the limit \Delta -> -1^+ for both open and periodic boundary conditions. At \Delta=-1 (ferromagnetic point) the model is… Expand
