Thermal entanglement in the two-qubit Heisenberg XYZ model
G. Rigolin
We study the entanglement of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium at temperature T. We obtain an analytical expression for the entanglement of fo…
AdS Geometry, projective embedded coordinates and associated isometry groups
Roldao da Rocha, E. Capelas de Oliveira
This work is intended to investigate the geometry of anti-de Sitter spacetime (AdS), from the point of view of the Laplacian Comparison Theorem (LCT), and to give another descripti…
Domain wall scattering in an interacting one-dimensional electron gas
R. G. Pereira, E. Miranda
We study the transport in a Luttinger liquid coupled to a magnetic chain containing a Bloch domain wall. We compute the leading correction to the adiabatic limit of a long domain w…
On the nature of ferromagnetism in Ga_{1-x}Mn_xAs semiconductors
A. J. R. da Silva, A. Fazzio, R. R. dos Santos +1
We have performed ab initio calculations within the density-functional theory for Ga_{1-x}Mn_xAs diluted semiconductors. Total energy results unambiguously show that a quasi-locali…
Almost summing mappings
Daniel M. Pellegrino
We introduce a general definition of almost -summing mappings and give several concrete examples of such mappings. Some known results are considerably generalized and we present…
Dynamics of topological defects in a spiral: a scenario for the spin-glass phase of cuprates
V. Juricic, L. Benfatto, A. O. Caldeira +1
We propose that the dissipative dynamics of topological defects in a spiral state is responsible for the transport properties in the spin-glass phase of cuprates. Using the collect…
