Instantons and radial excitations in attractive bose-einstein condensates... The mass parameter for theradial motion is found different from the gaussian value assumed hitherto, butthe effect of this difference on decay exponents is small....
Flatness of tracer density profile produced by a point source in turbulence... An explicit formula for the excess flatness at first order demonstrates maximum deviation from a Gaussian profile at time t of the order of five times the velocity correlation time, with a t–1 decay to the Gaussian value at large times....
Non-fickian diffusion in colloidal glasses... We show that, in line with theoretical predictions, the super-Burnett coefficient (characterizing the deviation of the fourth moment of the single particle distribution from its Gaussian value) is finite....
Uppsala universitycomputations of the green’s function and its fourier coefficients on psl(2, z)... Our results indicate that both the Green’s function and its Fourier coefficients may have a Gaussian value distribution in the semiclassical limit....
