On a heuristic point of view related to quantum nonequilibrium statistical mechanics
Norton G. de Almeida
In this paper I propose a new way for counting the microstates of a system out of equilibrium. As, according to quantum mechanics, things happen as if a given particle can be found…
Partial teleportation of entangled atomic states
W. B. Cardoso, N. G. de Almeida
In this paper we propose a scheme for partially teleporting entangled atomic states. Our scheme can be implemented using only four two-level atoms interacting either resonantly or…
Nonadiabatic coherent evolution of two-level systems under spontaneous decay
F. O. Prado, E. I. Duzzioni, M. H. Y. Moussa +2
In this paper we extend current perspectives in engineering reservoirs by producing a time-dependent master equation leading to a nonstationary superposition equilibrium state that…
Accuracy of a teleported trapped field state inside a single bimodal cavity
Iara P. de Queiros, Simone Souza, W. B. Cardoso +1
We propose a simplified scheme to teleport a superposition of coherent states from one mode to another of the same bimodal lossy cavity. Based on current experimental capabilities,…
Formal equivalence between Tsallis and extended Boltzmann-Gibbs statistics
N. G. de Almeida
A formal correspondence between the q-distribution obtained from the Tsallis entropy and non-maxwellian distributions obtained from the Boltzmann-Gibbs entropy is afforded.
Truncated states obtained by iteration
W. B. Cardoso, N. G. de Almeida
Quantum states of the electromagnetic field are of considerable importance, finding potential application in various areas of physics, as diverse as solid state physics, quantum co…
