The properties of a strongly correlated many-body quantum system, from the presence of
topological order to the onset of quantum criticality, leave a footprint in its entanglement …

The concept of entanglement in systems where the particles are indistinguishable has been
the subject of much recent interest and controversy. In this paper we study the notion of …

Much has been learned about universal properties of entanglement entropies in ground
states of quantum many-body lattice systems. Here we unveil universal properties of the …

We construct entanglement witnesses using fundamental quantum operators of spin models
which contain two-particle interactions and have a certain symmetry. By choosing the …

We study dynamical phase transitions (DPTs) in quantum many-body systems with infinite-
range interaction, and present a theory connecting the two kinds of known DPTs (sometimes …

We introduce a class of states, called minimally entangled typical thermal states, designed to
resemble a typical state of a quantum system at finite temperature with a bias towards …

We review different descriptions of many-body quantum systems in terms of tensor product
states. We introduce several families of such states in terms of the known renormalization …

The power of matrix product states to describe infinite-size translational-invariant critical spin
chains is investigated. At criticality, the accuracy with which they describe ground-state …
