A method for the dynamics of vortices in a Bose-Einstein condensate: analytical equations of the trajectories of phase singularities
S. de María-García, A. Ferrando, J. A. Conejero +2
We present a method to study the dynamics of a quasi-two dimensional Bose-Einstein condensate which contains initially many vortices at arbitrary locations. We present first the an…
Sub-nK thermometry of an interacting -dimensional homogeneous Bose gas
Muhammad Miskeen Khan, Mohammad Mehboudi, Hugo Tercas +2
We propose experimentally feasible means for non-destructive thermometry of homogeneous Bose Einstein condensates in different spatial dimensions (). Our impurity ba…
Heat current control in trapped BEC
Christos Charalambous, Miguel-Angel Garcia-March, Mohammad Mehboudi +1
We investigate the heat transport and the control of heat current among two spatially separated trapped Bose-Einstein Condensates (BEC), each of them at a different temperature. To…
Mesoscopic superpositions of Tonks-Girardeau states and the Bose-Fermi mapping
M. A. García-March, A. V. Yuste-Roca, B. Juliá-Díaz +1
We study a one dimensional gas of repulsively interacting ultracold bosons trapped in a double-well potential as the atom-atom interactions are tuned from zero to infinity. We conc…
Distinguishability, degeneracy and correlations in three harmonically trapped bosons in one-dimension
M. A. García-March, B. Juliá-Díaz, G. E. Astrakharchik +2
We study a system of two bosons of one species and a third boson of a second species in a one-dimensional parabolic trap at zero temperature. We assume contact repulsive inter- and…
Josephson physics of spin-orbit coupled elongated Bose-Einstein condensates
M. A. Garcia-March, G. Mazzarella, L. Dell'Anna +3
We consider an ultracold bosonic binary mixture confined in a one-dimensional double-well trap. The two bosonic components are assumed to be two hyperfine internal states of the sa…
Sharp crossover from composite fermionization to phase separation in mesoscopic mixtures of ultracold bosons
M. A. Garcia-March, B. Julia-Diaz, G. E. Astrakharchik +3
We show that a two-component mixture of a few repulsively interacting ultracold atoms in a one-dimensional trap possesses very different quantum regimes and that the crossover betw…
Symmetry breaking and singularity structure in Bose-Einstein condensates
K. A. Commeford, M. A. Garcia-March, A. Ferrando +1
We determine the trajectories of vortex singularities that arise after a single vortex is broken by a discretely symmetric impulse in the context of Bose-Einstein condensates in a…
Vortex macroscopic superpositions in ultracold bosons in a double-well potential
M. A. Garcia-March, Lincoln D. Carr
We study macroscopic superpositions in the orbital rather than the spatial degrees of freedom, in a three-dimensional double-well system. We show that the ensuing dynamics of i…
Macroscopic superposition states of ultracold bosons in a double-well potential
M. A. Garcia-March, D. R. Dounas-Frazer, Lincoln D. Carr
We present a thorough description of the physical regimes for ultracold bosons in double wells, with special attention paid to macroscopic superpositions (MSs). We use a generaliza…
Macroscopic Superposition of Ultracold Atoms with Orbital Degrees of Freedom
M. A. Garcia-March, D. R. Dounas-Frazer, Lincoln D. Carr
We introduce higher dimensions into the problem of Bose-Einstein condensates in a double-well potential, taking into account orbital angular momentum. We completely characterize th…
