Fracture and Friction: Stick-Slip Motion
Efim A. Brener, S. V. Malinin, V. I. Marchenko
We discuss the stick-slip motion of an elastic block sliding along a rigid substrate. We argue that for a given external shear stress this system shows a discontinuous nonequilibri…
Sound propagation and oscillations of a superfluid Fermi gas in the presence of a 1D optical lattice
L. P. Pitaevskii, S. Stringari, G. Orso
We develop the hydrodynamic theory of Fermi superfluids in the presence of a periodic potential. The relevant parameters governing the propagation of sound (compressibility and eff…
Measurement of Turbulence in Superfluid 3He-B
A. P. Finne, S. Boldarev, V. B. Eltsov +1
The experimental investigation of superfluid turbulence in 3He-B is generally not possible with the techniques which have been developed for 4He-II. We describe a new method by whi…
Heat Transfer in Superfluids: Effect of Gravity
L. A. Melnikovsky
We discuss the influence of an external field on energy transport in superfluid. He-II is not isothermal in presence of Earth gravity; instead, it supports finite temperature gradi…
Thermodynamics of Superfluidity
A. F. Andreev, L. A. Melnikovsky
New, superfluid specific additive integral of motion is found. This facilitates investigation of general thermodynamic equilibrium conditions for superfluid. The analysis is perfor…
Propagation of sound in a Bose Einstein condensate in an optical lattice
C. Menotti, M. Kramer, A. Smerzi +2
We study the propagation of sound waves in a Bose-Einstein condensate trapped in a one-dimensional optical lattice. We find that the velocity of propagation of sound wavepackets de…
Umklapp collisions and center of mass oscillation of a trapped Fermi gas
G. Orso, L. P. Pitaevskii, S. Stringari
Starting from the the Boltzmann equation, we study the center of mass oscillation of a harmonically trapped normal Fermi gas in the presence of a one-dimensional periodic potential…
Vortex formation in neutron-irradiated rotating superfluid 3He-B
A. P. Finne, S. Boldarev, V. B. Eltsov +1
A convenient method to create vortices in meta-stable vortex-free superflow of 3He-B is to irradiate with thermal neutrons. The vortices are then formed in a rapid non-equilibrium…
Insulating Behavior of a Trapped Ideal Fermi Gas
L. Pezze', L. Pitaevskii, A. Smerzi +7
We investigate theoretically and experimentally the center-of-mass motion of an ideal Fermi gas in a combined periodic and harmonic potential. We find a crossover from a conducting…
Tkachenko oscillations and the compressibility of a rotating Bose gas
M. Cozzini, L. P. Pitaevskii, S. Stringari
The elastic oscillations of the vortex lattice of a cold Bose gas (Tkachenko modes) are shown to play a crucial role in the saturation of the compressibility sum rule, as a consequ…
