Topologically trapped vortex molecules in Bose-Einstein condensates
R. Geurts, M. V. Milošević, F. M. Peeters
In a numerical experiment based on Gross-Pitaevskii formalism, we demonstrate unique topological quantum coherence in optically trapped Bose-Einstein condensates (BECs). Exploring…
Phase separation in imbalanced fermion superfluids beyond mean-field
J. Tempere, S. N. Klimin, J. T. Devreese
The density distributions of the two components of a trapped, ultracold Fermi gas with population imbalance reveal the effect of imbalance on superfluid pairing. We develop a path-…
Proposed definitions of the correlation energy density from a Hartree-Fock starting point: The two-electron Moshinsky model atom as an exactly solvable model
N. H. March, A. Cabo, F. Claro +1
In both molecular physics and condensed matter theory, deeper understanding of the correlation energy density epsilon_c (r) remains a high priority. By adopting Loewdin's definitio…
Electron Emission in Superfluid and Low-temperature Vapor Phase Helium
Isaac F. Silvera, Jacques Tempere
Tungsten filaments used as sources of electrons in a low temperature liquid or gaseous helium environment have remarkable properties of operating at thousands of degrees Kelvin in…
Molecules in clusters: the case of planar LiBeBCNOF built from a triangular form LiOB and a linear four-center species FBeCN
G. Forte, A. Grassi, G. M. Lombardo +3
Krueger some years ago proposed a cluster LiBeBCNOF, now called periodane. His ground-state isomer proposal has recently been refined by Bera et al. using DFT. Here, we take the ap…
Quantised Vortices in an Exciton-Polariton Fluid
K. G. Lagoudakis, M. Wouters, M. Richard +5
One of the most striking quantum effects in a low temperature interacting Bose gas is superfluidity. First observed in liquid 4He, this phenomenon has been intensively studied in a…
