Origin of spin incommensurability in hole-doped S=1 Y2-xCaxBaNiO5 chains
(American Physical Soc, 2001-04-01)
Spin incommensurability (IC) has been recently experimentally discovered in the hole-doped Ni-oxide chain compound Y2-xCaxBaNiO5 [G. Xu et al., Science 289, 419 (2000)]. Here a two orbital model for this material is studied ...
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 ...

Exactly conserved quasilocal operators for the XXZ spin chain
(Institute of Physics - IOPBristol, 2014-09)
We extend T Prosen’s construction of quasilocal conserved quantities for the XXZ model (2011 Phys. Rev. Lett. 106 217206) to the case of periodic boundary conditions. These quasilocal operators stem from a two-parameter ...
