Entanglement dynamics after quantum quenches in generic integrable systems
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
Entanglement and thermodynamics after a quantum quench in integrable systems
TLDR
It is shown that the standard quasiparticle picture of the entanglement evolution, complemented with integrability-based knowledge of the steady state and its excitations, leads to a complete understanding of theEntanglement dynamics in the space–time scaling limit.
Entanglement entropy of excited states
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
Boundary-locality and perturbative structure of entanglement spectra in gapped systems.
TLDR
Focusing on gapped phases of several one-dimensional systems, it is shown how this spectrum is dominated by contributions from the boundary between the parts, contradicting the view of an "entanglement Hamiltonian" as a bulk entity.
Quantum information dynamics in multipartite integrable systems
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.
Eigenstate thermalization hypothesis and integrability in quantum spin chains
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
Bound states and entanglement in the excited states of quantum spin chains
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
Generalized Hydrodynamics with Space-Time Inhomogeneous Interactions.
TLDR
A new hydrodynamic framework to describe out-of-equilibrium integrable systems with space-time inhomogeneous interactions with classical sinh-Gordon model is provided.
Entanglement negativity and conformal field theory: a Monte Carlo study
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)
Entanglement spectrum of the Heisenberg XXZ chain near the ferromagnetic point
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
