Controlled transitions between phyllotactic states of repulsive particles confined on the surface of a cylinder
A. A. Tomlinson, N. K. Wilkin
Phyllotactic states are regular lattice-like structures on cylinders and are a botanical classification scheme. In this communication, we report a sequence of transitions between p…
Transitions between phyllotactic lattice states in curved geometries
H. S. Ansell, A. A. Tomlinson, N. K. Wilkin
Phyllotaxis, the regular arrangement of leaves or other lateral organs in plants including pineapples, sunflowers and some cacti, has attracted scientific interest for centuries. M…
Extruding the vortex lattice: two reacting populations of dislocations
Jonathan S. Watkins, Nicola K. Wilkin
A controllable soft solid is realised in vortex matter in a type II superconductor. The two-dimensional unit cell area can be varied by a factor of in the solid phase, witho…
Instabilities and "phonons" of optical lattices in hollow optical fibers
N. K. Wilkin, J. M. F. Gunn
Instabilities are predicted for a sufficiently long hollow photonic optical fiber, or "cavity", containing a one dimensional Bose-gas in the presence of a classical, far red-detune…
Exact vortex nucleation and cooperative vortex tunneling in dilute BECs
M. I. Parke, N. K. Wilkin, J. M. F. Gunn +1
With the imminent advent of mesoscopic rotating BECs in the lowest Landau level (LLL) regime, we explore LLL vortex nucleation. An exact many-body analysis is presented in a weakly…
Anomalous hydrodynamics and "normal" fluids in rapidly rotating BECs
A. Bourne, N. K. Wilkin, J. M. F. Gunn
In rapidly rotating bose systems we show that there is a region of anomalous hydrodynamics whilst the system is still condensed, which coincides with the mean field quantum Hall re…
