Ultracold atoms in quasi-1D traps: a step beyond the Lieb-Liniger model
Krzysztof Jachymski, Florian Meinert, Hagar Veksler +2
Ultracold atoms placed in a tight cigar-shaped trap are usually described in terms of the Lieb-Liniger model. We study the extensions of this model which arise when van der Waals i…
Buckling transitions and clock order of two-dimensional Coulomb crystals
Daniel Podolsky, Efrat Shimshoni, Giovanna Morigi +1
Crystals of repulsively interacting ions in planar traps form hexagonal lattices, which undergo a buckling instability towards a multi-layer structure as the transverse trap freque…
A generalized Lieb-Liniger model
Hagar Veksler, Shmuel Fishman
In 1963, Lieb and Liniger solved exactly a one dimensional model of bosons interacting by a repulsive δ-potential and calculated the ground state in the thermodynamic limit. In the…
A simple model for interactions and corrections to the Gross-Pitaevskii Equation
Hagar Veksler, Shmuel Fishman, Wolfgang Ketterle
One of the assumptions leading to the Gross-Pitaevskii Equation (GPE) is that the interaction between atom pairs can be written effectively as a δ-function so that the interaction…
