Entanglement versus chaos in disordered spin chains

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 ...
Exact field-driven interface dynamics in the two-dimensional stochastic Ising model with helicoidal boundary conditions
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We investigate the interface dynamics of the two-dimensional stochastic Ising model in an external field under helicoidal boundary conditions. At sufficiently low temperatures and fields, the dynamics of the interface is ...
Magnetization plateaus and Luttinger liquid behavior in XXZ chains with superlattice structure
(American Physical SocCollege PkEUA, 2002)
Quantum correlations and coherence in spin-1 Heisenberg chains
(2016-05-24)
We explore quantum and classical correlations along with coherence in the ground states of spin-1 Heisenberg chains, namely the one-dimensional XXZ model and the one-dimensional bilinear biquadratic model, with the techniques ...
Quantum Correlations And Coherence In Spin-1 Heisenberg Chains

Retificação de energia e magnetização em cadeias quânticas de spin: análise do modelo XXZ
(Universidade Federal de Minas GeraisUFMG, 2016-08-11)
We addressed the issue of energy and magnetization rectification in the quantum one-dimensional open XXZ spin chain driven out of equilibrium by magnetization pumping applied at its boundaries and in the presence of an ...
Universal behavior of the Shannon mutual information of critical quantum chains
(American Physical Society - APSCollege Park, 2013-07)
We consider the Shannon mutual information of subsystems of critical quantum chains in their ground states. Our results indicate a universal leading behavior for large subsystem sizes. Moreover, as happens with the ...
