Quantum and classical correlations and Werner states in finite spin linear arrays
P. R. Wells, C. M. Chaves, J. A. e. Castro +1
Pairwise quantum correlations in the ground state of a N-spins antiferromagnetic chain described by the Heisenberg model with nearest neighbor exchange coupling are investigated. B…

Quantum and classical correlations in antiferromagnetic chains and the realization of Werner states with spins
P. R. Wells, Belita Koiller
We investigate pairwise correlation properties of the ground state (GS) of finite antiferromagnetic (AFM) spin chains described by the Heisenberg model. The exchange coupling is re…

Quantum Diffusion and Localization in Disordered Electronic Systems
P. R. Wells, J. d'Albuquerque e Castro, S. L. A. de Queiroz
The diffusion of electronic wave packets in one-dimensional systems with on-site, binary disorder is numerically investigated within the framework of a single-band tight-binding mo…
