Quantum Conductance and Electrical Resistivity
P. R. Silva, Marcos Sampaio, C. Nassif +1
The Landauer formula for quantum conductance, based on the modern paradigm: "conduction is transmission", is generalized to samples of macroscopic size. Two regimes of electrical c…
Stern-Gerlach Entanglement in Spinor Bose-Einstein Condensates
S. Cruz-Barrios, M. C. Nemes, A. F. R. de Toledo Piza
Entanglement of spin and position variables produced by spatially inhomogeneous magnetic fields of Stern-Gerlach type acting on spinor Bose-Einstein condensates may lead to interfe…
Density Matrix of a Bose--Einstein Condensate: Steady--State versus Mean--Field Approach
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We compare the equilibrium solution for the condensate obtained in the mean--field approximation to the master equation for sympathetic cooling with the one obtained by Scully for…
Mean-Field Approximation to the Master Equation for Sympathetic Cooling of Trapped Bosons
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We use the mean-field approximation to simplify the master equation for sympathetic cooling of Bosons. For the mean single-particle occupation numbers, this approach yields the sam…
