Stochastic resonance in periodic potentials: realization in a dissipative optical lattice

Michele Schiavoni, Francois-Regis Carminati, Laurent Sanchez-Palencia +2

We have observed the phenomenon of stochastic resonance on the Brillouin propagation modes of a dissipative optical lattice. Such a mode has been excited by applying a moving poten…

Thermal transport in one-dimensional spin gap systems

E. Orignac, R. Chitra, R. Citro

We study thermal transport in one dimensional spin systems both in the presence and absence of impurities. In the absence of disorder, all these spin systems display a temperature…

133Cs87Rb Laser Cooled Dual Fountain

D. Calonico, Y. Sortais, S. Bize +5

At BNM-SYRTE laboratories in Paris two 133Cs fountains and a 87Rb one have been already demonstrated. This paper illustrates the construction of a 87Rb and Cs dual fountain realize…

Rationalite des series de Poincare et des fonctions Zeta motiviques

Julien Sebag

If k is a field of characteristic 0, we prove that the motivic Poincare serie and the motivic Zeta functions associated to a k[[t]]-variety, flat and purely dimensional, are ration…

Algebraic Approach to q,t-Characters

David Hernandez

Frenkel and Reshetikhin introduced q-characters to study finite dimensional representations of quantum affine algebras. In the simply laced case Nakajima defined deformations of q-…

Extension of Bogoliubov theory to quasi-condensates

Christophe Mora, Yvan Castin

We present an extension of the well-known Bogoliubov theory to treat low dimensional degenerate Bose gases in the limit of weak interactions and low density fluctuations. We use a…
