Super-Tonks-Girardeau state in an attractive one-dimensional dipolar gas.
The ground state of a one-dimensional (1D) quantum gas of dipoles oriented perpendicular to the longitudinal axis, with a strong 1/x(3) repulsive potential, is studied at low 1D densities n. Near contact the dependence of the many-body wave function on the separation x(jℓ) of two particles reduces to a two-body wave function Ψ(rel)(x(jℓ)). Immediately after a sudden rotation of the dipoles so t...
متن کاملStatic and dynamic properties of trapped fermionic Tonks-Girardeau gases.
We investigate some static and dynamic properties of harmonically trapped fermionic Tonks-Girardeau gases in tight de Broglie waveguides with attractive p-wave interactions induced by a Feshbach resonance. An exact solution for the one-body density matrix is analyzed in terms of its natural orbitals, with the surprising result that for odd, but not for even, numbers of fermions the maximally oc...
متن کاملStrongly interacting Fermi gases
Measurements have confirmed a theoretical prediction published in 2006: all strongly interacting Fermi gases were predicted to show identical thermodynamic behaviour. Late in 2006, detailed experimental data became available for the first time, for different fermions under different conditions. All the new data lies on a single universal curve, exactly as we predicted. This is an outstanding di...
متن کاملQuantum Mechanics of One-Dimensional Trapped Tonks Gases
Several experimental groups are currently working towards realizing quasione-dimensional (1D) atom de Broglie waveguides and loading them with ultracold atoms. The dynamics becomes truly 1D in a regime (Tonks gas) of low temperatures and densities, and large positive scattering lengths for which the transverse mode becomes frozen, in which case the many-body Schrödinger dynamics becomes exactly...
