This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …

Quantum entanglement marks a definitive feature of topological states. However, the
entanglement spectrum remains insufficiently explored for topological states without a bulk …

We discuss the characterization and stability of the Haldane phase in integer spin chains on
the basis of simple, physical arguments. We find that an odd-S Haldane phase is a …

The fermion disorder operator has been shown to reveal the entanglement information in 1D
Luttinger liquids and 2D free and interacting Fermi and non-Fermi liquids emerging at …

The ground state of translationally invariant insulators comprises bands which can assume
topologically distinct structures. There are few known examples where this distinction is …

We consider (2+ 1)-dimensional topological quantum states which possess edge states
described by a chiral (1+ 1)-dimensional conformal field theory, such as, eg, a general …

We investigate in detail the behavior of the bipartite fluctuations of particle number N ̂ and
spin S ̂ z in many-body quantum systems, focusing on systems where such U (1) charges …

In many physical scenarios, close relations between the bulk properties of quantum systems
and theories associated with their boundaries have been observed. In this work, we provide …

There is no doubt that the information hidden in entanglement entropy (EE), for example, the
n th order Rényi EE, ie, S n A= 1 1− n ln Tr (ρ A n), where ρ A= Tr A¯ ρ is the reduced density …

In closed systems, the celebrated Lieb–Schultz–Mattis (LSM) theorem states that a one-
dimensional locally interacting half-integer spin chain with translation and spin rotation …
