Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

We review recent theoretical work on two closely related issues: excitation of an isolated
quantum condensed matter system driven adiabatically across a continuous quantum phase …

We study the unitary time evolution of the entropy of entanglement of a one-dimensional
system between the degrees of freedom in an interval of length and its complement, starting …

The transverse field Ising and XY models (the simplest quantum spin models) provide the
organising principle for the rich variety of interconnected subjects which are covered in this …

We study in general the time evolution of correlation functions in a extended quantum
system after the quench of a parameter in the Hamiltonian. We show that correlation …

We present an introductory overview of the use of spin chains as quantum wires, which has
recently developed into a topic of lively interest. The principal motivation is in connecting …

We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

We show that the dynamics resulting from preparing a one-dimensional quantum system in
the ground state of two decoupled parts, then joined together and left to evolve unitarily with …

We demonstrate how quantum entanglement can be directly witnessed in the quasi-1D
Heisenberg antiferromagnet KCuF 3. We apply three entanglement witnesses—one tangle …

By means of the time dependent density matrix renormalization group algorithm we study
the zero-temperature dynamics of the Von Neumann entropy of a block of spins in a …
