Phase dynamics after connection of two separate Bose-Einstein condensates
I. Zapata, F. Sols, A. J. Leggett
We study the dynamics of the relative phase following the connection of two independently formed Bose-Einstein condensates. Dissipation is assumed to be due to the creation of quas…
The Josephson plasmon as a Bogoliubov quasiparticle
G. -S. Paraoanu, S. Kohler, F. Sols +1
We study the Josephson effect in alkali atomic gases within the two-mode approximation and show that there is a correspondence between the Bogoliubov description and the harmonic l…
Ground-State Properties of a Rotating Bose-Einstein Condensate with Attractive Interaction
Masahito Ueda, Anthony J. Leggett
The ground state of a rotating Bose-Einstein condensate with attractive interaction in a quasi-one-dimensional torus is studied in terms of the ratio of the mean-field interact…
Macroscopic Quantum Tunneling of a Bose-Einstein Condensate with Attractive Interaction
Masahito Ueda, Anthony J. Leggett
A Bose-Einstein condensate with attractive interaction can be metastable if it is spatially confined and if the number of condensate bosons is below a certain critical value…
Josephson effect between trapped Bose-Einstein condensates
Ivar Zapata, Fernando Sols, Anthony J. Leggett
We study the Josephson effect between atomic Bose-Einstein condensates. By drawing on an electrostatic analogy, we derive a semiclassical functional expression for the three-dimens…
Experimental Constraints on the Pairing State of the Cuprate Superconductors: an Emerging Consensus
James Annett, Nigel Goldenfeld, Anthony Leggett
We present a critical discussion of recent experimental probes of the pairing state of the high temperature superconductors, focusing primarily, but not exclusively, on \Yba, where…
