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…
