Comment on ``Sound velocity and multibranch Bogoliubov spectrum of an elongated Fermi superfluid in the BEC-BCS crossover"
P. Capuzzi, P. Vignolo, F. Federici +1
The work by T. K. Ghosh and K. Machida [cond-mat/0510160 and Phys. Rev. A 73, 013613 (2006)] on the sound velocity in a cylindrically confined Fermi superfluid obeying a power-law…
Sound wave propagation in strongly elongated fermion clouds at finite collisionality
P Capuzzi, P Vignolo, F Federici +1
We evaluate the transition from zero-sound to first-sound behaviour with increasing collisionality in the propagation of density waves through an ultracold gaseous mixture of fermi…
Sound propagation in elongated superfluid fermion clouds
P. Capuzzi, P. Vignolo, F. Federici +1
We use hydrodynamic equations to study sound propagation in a superfluid Fermi gas inside a strongly elongated cigar-shaped trap, with main attention to the transition from the BCS…
Excised acoustic black holes: the scattering problem in the time domain
C. Cherubini, F. Federici, S. Succi +1
The scattering process of a dynamic perturbation impinging on a draining-tub model of an acoustic black hole is numerically solved in the time domain. Analogies with real black hol…
Superradiance from BEC vortices: a numerical study
F. Federici, C. Cherubini, S. Succi +1
The scattering of sound wave perturbations from vortex excitations of Bose-Einstein condensates(BEC) is investigated by numerical integration of the associated Klein-Gordon equatio…
The Crossover beteween Aslamazov-Larkin and Short Wavelength Fluctuations Regimes in HTS Conductivity Experiments
M. R. Cimberle, C. Ferdeghini, E. Giannini +5
We present paraconductivity (AL) measurements in three different high temperature superconductors: a melt textured sample, a epitaxial thin film…
