Entanglement of a Multiparticle Schroedinger Cat State
A. N. Salgueiro
We characterize the degree of entanglement of a subsystem of particles in a -two level system () initially prepared in a mesoscopic superposition $|ψ>=\int dθf(θ)…

Quasi-classical dynamics of interacting Bose condensates
A. N. Salgueiro, M. C. Nemes, M. D. Sampaio +1
The dynamics of the composition of uniform Bose condensates involving two species capable of reciprocal interconversion is treated in terms of a collective quasi-spin model. This c…
