Cooling many particles to very low temperatures
Almut Beige, Peter L. Knight, Giuseppe Vitiello
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently using a bichromatic interaction. The…
Spin Flavor Oscillation of Neutrinos in Rotating Gravitational Fields and Their Effects on Pulsar Kicks
G. Lambiase
The origin of high velocities of pulsars is studied by considering the spin-flip conversion of neutrinos propagating in a gravitational field of a protoneutron star. For a rotating…
Neutrino mixing as a source for cosmological constant
Massimo Blasone, Antonio Capolupo, Salvatore Capozziello +2
We report on recent results showing that neutrino mixing may lead to a non-zero contribution to the cosmological constant. This contribution is of a completely different nature wit…
Whistleron Gas in Magnetized Plasmas
Salvatore De Martino, Mariarosaria Falanga, Stephan I. Tzenov
We have studied the nonlinear dynamics of whistler waves in magnetized plasmas. Since plasmas and beam-plasma systems considered here are assumed to be weakly collisional, the poin…
Effective temperature in the quench of coarsening systems to and below
Federico Corberi, Eugenio Lippiello, Marco Zannetti
We overview the general scaling behavior of the effective temperature in the que nches of simple non disordered systems, like ferromagnets, to and below . Emphasis is on the b…
4-pole analysis of the two-dimensional Hubbard model
Satoru Odashima, Adolfo Avella, Ferdinando Mancini
The electronic states of the two-dimensional Hubbard model are investigated by means of a 4-pole approximation within the Composite Operator Method. In addition to the conventional…
