We derive a general relation between the nonanalyticities of the ground state energy and
those of a subclass of the multipartite generalized global entanglement (GGE) measure …

We demonstrate that the global-entanglement (GE) measure defined by Meyer and Wallach
[J. Math. Phys. 43, 4273 (2002)] is maximal at the critical point for the Ising chain in a …

We develop a general theory of the relation between quantum phase transitions (QPTs)
characterized by nonanalyticities in the energy and bipartite entanglement. We derive a …

We formalize and extend an operational multipartite entanglement measure introduced by
TR Oliveira, G. Rigolin, and MC de Oliveira, Phys. Rev. A 73, 010305 (R)(2006), through the …

We provide insight into the quantum correlations structure present in strongly correlated
systems beyond the standard framework of bipartite entanglement. To this aim we first …

The entanglement of quantum XY spin chains of arbitrary length is investigated via a
recently developed global measure suitable for generic quantum many-body systems. This …

Characterizing and quantifying quantum correlations in states of many-particle systems is at
the core of a full understanding of phase transitions in matter. In this work, we continue our …

We analyze correlations between subsystems for an extended Hubbard model exactly
solvable in one dimension, which exhibits a rich structure of quantum phase transitions …

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 study the competing effects of collective generalized measurements and interaction-
induced scrambling in the dynamics of an ensemble of spin-1/2 particles at the level of …
