Correlations between Complexity and Entanglement in a One-Dimensional XY Model
(MDPI AG, 2020-05)
Many people believe that the study of complex quantum systems may be simplified by first analyzing the static and dynamic entanglement present in those systems [Phys. Rev. A 66 (2002) 032110]. In this paper, we attempt to ...
Estudo do modelo XY vetorial de Blume-Emery-Griffiths: aplicações a sistemas magnéticos e a filmes de misturas de 3He-4He
(Universidade Federal de Minas GeraisUFMG, 2011-08-05)
The classical XY model, and an XY vectorial generalization of the Blume-Emery-Griffiths model (XY-VBEG), the latter one proposed by Berker and Nelson to describe the behavior of films of 3He-4He mixtures, are studied by ...
Factorization and criticality in the anisotropic XY chain via correlations
(Mdpi Ag, 2015-01-01)
In this review, we discuss the zero and finite temperature behavior of various bipartite quantum and total correlation measures, the skew information-based quantum coherence and the local quantum uncertainty in the thermal ...
Long time tails in the dynamics of the spatially inhomogeneous magnetization of dimerized isotropic XY chains for spin s=1/2
(Elsevier Science BvAmsterdamHolanda, 1997)
Mixing of d(x)(-y)(2)(2) and d(xy) superconducting states for different filling and temperature
(Elsevier B.V., 2002-05-01)
We investigate the solution of the gap equation for mixed order parameter symmetry states as a function of filling using a two-dimensional tight-binding model incorporating second-neighbor hopping for tetragonal and ...

Solitonic elliptical solutions in the classical XY-model
(ELSEVIER, 2006-10-01)
The solitonic-like solutions predicted by the continuum semi-classical two-dimensional XY-model are investigated using canonical Monte Carlo simulation. In particular, we verify the existence of kink states, and study their ...
