Tunnelling induced collapse of an atomic Bose-Einstein condensate in a double-well potential
E. Sakellari, N. P. Proukakis, C. S. Adams
The stability of a low temperature Bose-Einstein condensate with attractive interactions in one and three dimensional double-well potentials is discussed. In particular, the tunnel…
Josephson tunnelling of a phase-imprinted Bose-Einstein condensate in a time-dependent double-well potential
E. Sakellari, N. P. Proukakis, M. Leadbeater +1
This paper discusses the feasibility of experimental control of the flow direction of atomic Bose-Einstein condensates in a double-well potential using phase-imprinting. The flow i…
Josephson Current Counterflow in Atomic Bose-Einstein Condensates
E. Sakellari, N. P. Proukakis, M. Leadbeater +1
Josephson weak links in superconductors can be engineered such that the phase difference across the junction is (-junction),leading to the reversal of the current. The condi…
Josephson spectroscopy of a dilute Bose-Einstein condensate in a double-well potential
E. Sakellari, M. Leadbeater, N. J. Kylstra +1
The dynamics of a Bose-Einstein condensate in a double-well potential are analysed in terms of transitions between energy eigenstates. By solving the time-dependent and time-indepe…
