Landau damping of spin waves in trapped Boltzmann gases
Ultracold gas boltzmann spatial dependence
font style='font-size:12px;'>
2014/12/20
A semiclassical method is used to study Landau damping of transverse pseudo-spin waves in harmonically trapped ultracold gases in the collisionless Boltzmann limit. In this approach, the time evolutio...

2014/12/20
Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type effects...

2014/12/19
We calculate the superfluid transition temperature of homogeneous interacting Bose gases in three and two spatial dimensions using large-scale path integral Monte Carlo simulations (with up to N=105 p...
Higher-order Kerr terms allow ionization-free filamentation in gases
Higher-order Kerr ionization-free filamentation gases
font style='font-size:12px;'>
2010/11/16
We show that higher-order nonlinear indices ($n_4$, $n_6$, $n_8$, $n_{10}$) provide the main defocusing contribution to self-channeling of ultrashort laser pulses in air and Argon at 800 nm, in contr...
Interference of parametrically driven one dimensional ultracold gases
parametrically driven dimensional ultracold gases
font style='font-size:12px;'>
2010/10/27
We theoretically analyze interference patterns of parametrically driven one dimensional ultracold atomic gases. By modulating the interaction strength periodically in time, we propose to excite collec...
Everlasting Quantum Wave: NIST Physicists Predict New Form of Soliton in Ultracold Gases（图）
Quantum Wave NIST Physicists Predict Soliton Ultracold Gases
font style='font-size:12px;'>
2009/12/23
Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint ...
