Precession of Vortices in Dilute Bose-Einstein Condensates at Finite Temperature
B. G. Wild, D. A. W. Hutchinson
We demonstrate that the precessional frequencies of vortices in Bose Einstein condensates (BECs) are determined by a conservation law, and not by the lowest lying excitation energy…
The dynamics of coherence between coupled and decoupled one-dimensional quasicondensates
R. G. Scott, D. A. W. Hutchinson
We reproduce the sub-exponential decoherence of one-dimensional quasicondensates observed in recent experiments. Counter-intuitively, the quasicondensates may decohere even when st…
Quantum mechanical potentials related to the prime numbers and Riemann zeros
Daniel Schumayer, Brandon P. van Zyl, David A. W. Hutchinson
Prime numbers are the building blocks of our arithmetic, however, their distribution still poses fundamental questions. Bernhard Riemann showed that the distribution of primes coul…
Incoherence of Bose-Einstein condensates at supersonic speeds due to quantum noise
R. G. Scott, D. A. W. Hutchinson
We calculate the effect of quantum noise in supersonic transport of Bose-Einstein condensates. When an obstacle obstructs the flow of atoms, quantum fluctuations cause atoms to be…
Non-equilibrium dynamics: Studies of reflection of Bose-Einstein condensates
R. G. Scott, C. W. Gardiner, D. A. W. Hutchinson
The study of the non-equilibrium dynamics in Bose-Einstein condensed gases has been dominated by the zero-temperature, mean field Gross-Pitaevskii formalism. Motivated by recent ex…
Density functional theory of the trapped Fermi gas in the unitary regime
Brandon P. van Zyl, D. A. W. Hutchinson, Melodie Need
We investigate a density-functional theory (DFT) approach for an unpolarized trapped dilute Fermi gas in the unitary limit . A reformulation of the recent work of T. Papenbrock [Ph…
