Spin-polarized hydrogen adsorbed on the surface of superfluid 4He
J. M. Marin, L. Vranjes Markic, J. Boronat
The experimental realization of a thin layer of spin-polarized hydrogen adsorbed on top of the surface of superfluid 4He provides one of the best examples of a stable nearly two-di…
Breakdown of the scale invariance in the vicinity of Tonks-Girardeau gas
Z. D. Zhang, G. E. Astrakharchik, D. C. Aveline +4
In this article, we consider the monopole excitations of the harmonically trapped Bose gas in the vicinity of the Tonks-Girardeau limit. Using Girardeau's Fermi-Bose duality and su…
Gap solitons in the spin-orbit coupled Bose-Einstein condensates
Yaroslav V. Kartashov, Vladimir V. Konotop, Fatkhulla Kh. Abdullaev
We report a diversity of stable gap solitons in a spin-orbit coupled Bose-Einstein condensate subject to a spatially periodic Zeeman field. It is shown that the solitons, can be cl…
Sharp crossover from composite fermionization to phase separation in mesoscopic mixtures of ultracold bosons
M. A. Garcia-March, B. Julia-Diaz, G. E. Astrakharchik +3
We show that a two-component mixture of a few repulsively interacting ultracold atoms in a one-dimensional trap possesses very different quantum regimes and that the crossover betw…
Dynamic structure function of a cold Fermi gas at unitarity
G. E. Astrakharchik, J. Boronat, E. Krotscheck +1
We present a theoretical study of the dynamic structure function of a resonantly interacting two-component Fermi gas at zero temperature. Our approach is based on dynamic many-body…
Trapped one-dimensional ideal Fermi gas with a single impurity
G. E. Astrakharchik, I. Brouzos
Properties of a single impurity in a one-dimensional Fermi gas are investigated in homogeneous and trapped geometries. In a homogeneous system we use McGuire's expression [J. B. Mc…
