We investigate the scaling and spatial distribution of genuine multiparticle entanglement in
three-and four-spin reduced states of the one-dimensional XY model at the quantum phase …

We consider the isotropic Heisenberg model in a magnetic field in the strong-rung-coupling
limit on a two-dimensional (2D) rectangular zig-zag lattice of arbitrary size, and determine …

Multiparty quantum states are useful for a variety of quantum information and computation
protocols. We define a multiparty entanglement measure based on local measurements on a …

We investigate the behavior of genuine multiparticle entanglement, as quantified by the
generalized geometric measure, in gapless-to-gapped quantum transitions of one-and two …

Computing entanglement of an arbitrary bipartite or multipartite mixed state is in general not
an easy task as it usually involves complex optimization. Here we show that, exploiting …

A complementarity relation is established between the capacity of multiport classical
information transmission via quantum states and multiparty quantum correlation measures …

We consider a class of large superposed states, obtained from dimer coverings on spin-1/2
isotropic lattices, whose potential usefulness ranges from organic molecules to quantum …

Phase transition in quantum many-body systems inevitably causes changes in certain
physical properties which then serve as potential indicators of critical phenomena. Besides …

It is well known that the notions of spatial locality are often lost in quantum systems with long-
range interactions, as exhibited by the emergence of phases with exotic long-range order …

We investigate finite-size scaling of genuine multisite entanglement in the ground state of
quantum spin-1/2 Heisenberg ladders. We obtain the ground states of odd-and even-legged …
