Josephson dynamics and localization revivals in ultradilute quantum liquids
Piotr Wysocki, Krzysztof Jachymski, Grigori E. Astrakharchik +1
We study the Josephson junction made of a one-dimensional ultradilute quantum liquid in a double-well potential. We analyze the dynamics as a function of the interaction strength a…
Self-Assembled Chains and Solids of Dipolar Atoms in a Multilayer
G. Guijarro, G. E. Astrakharchik, G. Morigi +1
We predict that ultracold bosonic dipolar gases, confined within a multilayer geometry, may undergo self-assembling processes, leading to the formation of chain gases and solids. T…
Superfluid fraction of interacting bosonic gases
Daniel Pérez-Cruz, Grigori E. Astrakharchik, Pietro Massignan
The superfluid fraction of a quantum fluid is defined in terms of the response of the system to a weak and constant drag. Notably, Leggett long ago derived two simple expressio…
Superfluid rings as quantum pendulums
Antonio Muñoz Mateo, Grigory E. Astrakharchik, Bruno Juliá-Díaz
A feasible experimental proposal to realize a non-dispersive quantum pendulum is presented. The proposed setup consists of an ultracold atomic cloud, featuring attractive interatom…
Gas-to-soliton transition of attractive bosons on a spherical surface
A. Tononi, G. E. Astrakharchik, D. S. Petrov
We investigate the ground state properties of bosons with attractive zero-range interactions characterized by the scattering length and confined to the surface of a spher…
Asymmetric Bethe Ansatz
Steven G. Jackson, Hélène Perrin, Gregory E. Astrakharchik +1
The recently proposed exact quantum solution for two -function-interacting particles with a mass-ratio in a hard-wall box [Y. Liu, F. Qi, Y. Zhang and S. Chen, iScienc…
