Coupling for some partial differential equations driven by white noise
Giuseppe Da Prato, Arnaud Debussche, Luciano Tubaro
We prove, using coupling arguments, exponential convergence to equilibrium for reaction--diffusion and Burgers equations driven by space-time white noise. We use a coupling by refl…
Effect of the Casimir-Polder force on the collective oscillations of a trapped Bose-Einstein condensate
Mauro Antezza, Lev P. Pitaevskii, Sandro Stringari
We calculate the effect of the interaction between an optically active material and a Bose-Einstein condensate on the collective oscillations of the condensate. We provide explicit…
A Terracini Lemma for osculating spaces with applications to Veronese surfaces
Edoardo Ballico, Claudio Fontanari
Here we present a partial generalization to higher order osculating spaces of the classical Lemma of Terracini on ordinary tangent spaces. As an application, we investigate the sec…
Probing microcavity polariton superfluidity through resonant Rayleigh scattering
Iacopo Carusotto, Cristiano Ciuti
We investigate the two-dimensional motion of polaritons injected into a planar microcavity by a continuous wave optical pump in presence of a static perturbation, e.g. a point defe…
On the surjectivity of the canonical Gaussian map for multiple coverings
Edoardo Ballico, Claudio Fontanari
Here we investigate the canonical Gaussian map for higher multiple coverings of curves, the case of double coverings being completely understood thanks to previous work by Duflot.…
