In 1924 the Indian physicist Satyendra Nath Bose sent Einstein a paper in which he derived the Planck law for black-body radiation by treating the photons as a gas of identical particles. Einstein…
Theory of ultracold atomic Fermi gases
- S. Giorgini, L. Pitaevskiĭ, S. Stringari
- Physics

The physics of quantum degenerate atomic Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is given to the effect of…
Quantum tricriticality and phase transitions in spin-orbit coupled Bose-Einstein condensates.
- Yun Li, L. Pitaevskiĭ, S. Stringari

- 14 February 2012
A spin-orbit coupled configuration of spin-1/2 interacting bosons with equal Rashba and Dresselhaus couplings is considered with special emphasis on the role of the interaction treated in the mean-field approximation.
Dynamics of Bose-Einstein condensed gases in highly deformed traps

We provide a unified investigation of normal modes and sound propagation at zero temperature in Bose-Einstein condensed gases confined in highly asymmetric harmonic traps and interacting with…
Collective mode of homogeneous superfluid Fermi gases in the BEC-BCS crossover (14 pages)
- R. Combescot, M. Kagan, S. Stringari
- Physics
- 19 July 2006
We perform a detailed study of the collective mode across the whole crossover from the Bose-Einstein condensate (BEC)-to the BCS regime in fermionic gases at zero temperature, covering the whole…
Measurement of the temperature dependence of the Casimir-Polder force.
- J. Obrecht, R. Wild, M. Antezza, L. Pitaevskiĭ, S. Stringari, E. Cornell
- PhysicsPhysical Review Letters
- 17 May 2006
The effect of the Casimir-Polder force is measured to be nearly 3 times larger for a 605 K substrate than for a room-temperature substrate, showing a clear temperature dependence in agreement with theory.
Magnetic Solitons in a Binary Bose-Einstein Condensate.
- C. Qu, L. Pitaevskiĭ, S. Stringari
- PhysicsPhysical Review Letters
- 19 February 2016
An analytical solution is obtained which reveals that the width and the velocity of magnetic solitons are explicitly related to the spin healing length and the spin sound velocity of the Bose mixture, respectively.
Overcritical rotation of a trapped Bose-Einstein condensate.
- A. Recati, F. Zambelli, S. Stringari
- PhysicsPhysical Review Letters
- 10 July 2000
The rotational motion of an interacting Bose-Einstein condensate confined by a harmonic trap is investigated by solving the hydrodynamic equations of superfluids, with the irrotationality constraint for the velocity field, and shows that in the case of isotropic trapping the system exhibits a bifurcation from an axisymmetric to a triaxial configuration.
Collective oscillations of a one-dimensional trapped Bose-Einstein gas
- C. Menotti, S. Stringari
- Physics
- 21 October 2002
Starting from the hydrodynamic equations of superfluids, we calculate the frequencies of the collective oscillations of a harmonically trapped Bose-Einstein gas for various one-dimensional…
