Emergence of singularities from decoherence: Quantum catastrophes
Aaron Z. Goldberg, Asma Al-Qasimi, J. Mumford +1
We use a master equation to study the dynamics of two coupled macroscopic quantum systems (e.g.\ a Josephson junction made of two Bose-Einstein condensates or two spin states of an…
Catastrophes in non-equilibrium many-particle wave functions: universality and critical scaling
J Mumford, W Kirkby, D H J O'Dell
As part of the quest to uncover universal features of quantum dynamics, we study catastrophes that form in simple many-body wave functions after a quench, focusing on two-mode syst…
Anisotropic and long-range vortex interactions in two-dimensional dipolar Bose gases
B. C. Mulkerin, R. M. W. van Bijnen, D. H. J. O'Dell +2
We perform a theoretical study into how dipole-dipole interactions modify the properties of superfluid vortices within the context of a two-dimensional atomic Bose gas of co-orient…
Quantum catastrophes and ergodicity in the dynamics of bosonic Josephson junctions
D. H. J. O'Dell
We study rainbow (fold) and cusp catastrophes that form in Fock space following a quench in a Bose Josephson junction. In the Gross-Pitaevskii mean-field theory the rainbows are si…
Collective excitation frequencies and stationary states of trapped dipolar Bose-Einstein condensates in the Thomas-Fermi regime
R. M. W. van Bijnen, N. G. Parker, S. J. J. M. F. Kokkelmans +2
We present a general method for obtaining the exact static solutions and collective excitation frequencies of a trapped Bose-Einstein condensate (BEC) with dipolar atomic interacti…
Classical versus quantum dynamics of the atomic Josephson junction
G. J. Krahn, D. H. J. O'Dell
We compare the classical (mean-field) dynamics with the quantum dynamics of atomic Bose-Einstein condensates in double-well potentials. The quantum dynamics are computed using a si…
Exact solutions and stability of rotating dipolar Bose-Einstein condensates in the Thomas-Fermi limit
R. M. W. van Bijnen, A. J. Dow, D. H. J. O'Dell +2
We present a theoretical analysis of dilute gas Bose-Einstein condensates with dipolar atomic interactions under rotation in elliptical traps. Working in the Thomas-Fermi limit, we…
