Quantum information theory has considerably helped in the understanding of quantum many- body systems. The role of quantum correlations and in particular, bipartite entanglement …
We review recent developments in the physics of ultracold atomic and molecular gases in optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …
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 …
We investigate the presence of multipartite entanglement in macroscopic spin chains. We discuss the Heisenberg and the XY model and derive bounds on the internal energy for …
Is the closest product state to a symmetric entangled multiparticle state also symmetric? This question has appeared in the recent literature concerning the geometric measure of …
In this work, we address the ground-state properties of the anisotropic spin-1/2 Heisenberg XYZ chain under the interplay of magnetic fields and the Dzyaloshinskii-Moriya (DM) …
We introduce a class of generalized geometric measures of entanglement. For pure quantum states of N elementary subsystems, they are defined as the distances from the sets …
We propose a detailed study of the geometric entanglement properties of pure symmetric N- qubit states, focusing more particularly on the identification of symmetric states with a high …
In this work, we present some new understanding of topological order, including three main aspects.(1) It was believed that classifying topological orders corresponds to classifying …
