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)
Transmissão de emaranhamento através de cadeias de spins
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em FísicaCâmpus São Carlos, 2018-04-25)
In this thesis we studied the transmission of entangled states in unmodulated spin chains using a slight modification in the XY isotropic model (XX model) that describes a one-dimensional spin-1/2 chain. We have shown that ...
Thermal transport in one-dimensional spin heterostructures
(American Physical Society, 2009-07)
We study heat transport in a one-dimensional inhomogeneous quantum spin-1/2 system. It consists of a finite-size XX spin chain coupled at its ends to semi-infinite XX and XY chains at different temperatures, which play the ...
Symmetry-breaking effects upon bipartite and multipartite entanglement in the XY model

Quantum discord and related measures of quantum correlations in XY chains

Quantum coherence and uncertainty in the anisotropic XY chain
(Amer Physical Soc, 2014-09-30)
We explore the local quantum coherence and the local quantum uncertainty, based on Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in a transverse magnetic field. We show that the ...
