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…
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…
Atom Chip Diffraction of Bose-Einstein Condensates: The Role of Inter-Atomic Interactions
T. E. Judd, R. G. Scott, T. M. Fromhold
We use supercomputer simulations to show that inter-atomic interactions can strongly affect the phase evolution of Bose-Einstein condensates that are diffracted from atom chips, th…
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…
Transmission and Reflection of Bose-Einstein Condensates Incident on a Gaussian Potential Barrier
A. M. Martin, R. G. Scott, T. M. Fromhold
We investigate how Bose-Einstein condensates, whose initial state is either irrotational or contains a single vortex, scatter off a one-dimensional Gaussian potential barrier. We f…
Disruption of reflecting Bose-Einstein condensates due to inter-atomic interactions and quantum noise
R. G. Scott, D. A. W. Hutchinson, C. W. Gardiner
We perform fully three-dimensional simulations, using the truncated Wigner method, to investigate the reflection of Bose-Einstein condensates from abrupt potential barriers. We sho…
