Probing the limits of the rigid-intensity-shift model in differential phase contrast scanning transmission electron microscopy
L. Clark, H. G. Brown, D. M. Paganin +5
The rigid-intensity-shift model of differential phase contrast scanning transmission electron microscopy (DPC-STEM) imaging assumes that the phase gradient imposed on the probe by…
Bloch Sphere Catastrophes
Samuel A. Eastwood, David M. Paganin, Timothy C. Petersen +1
Caustics are optical phenomena which occur when a family of rays creates an envelope of divergent intensity. Here we show that caustic surfaces also appear when a real or complex f…
Texture control in a pseudospin Bose-Einstein condensate
Gary Ruben, Michael J. Morgan, David M. Paganin
We describe a wavefunction engineering approach to the formation of textures in a two-component nonrotated Bose-Einstein condensate. By controlling the phases of wavepackets that c…
Vortex-lattice formation and melting in a nonrotating Bose-Einstein condensate
Gary Ruben, David M. Paganin, Michael J. Morgan
Numerical simulations of the interference of a three-way segmented nonrotating Bose-Einstein condensate reveal the production of a honeycomb vortex lattice containing significant n…
Inferring the time-dependent complex Ginzburg-Landau equation from modulus data
Rotha P. Yu, David M. Paganin, Michael J. Morgan
We present a formalism for inferring the equation of evolution of a complex wave field that is known to obey an otherwise unspecified (2+1)-dimensional time-dependent complex Ginzb…
Inferring nonlinear parabolic field equations from modulus data
Rotha P. Yu, David M. Paganin, Michael J. Morgan
We give a means for measuring the equation of evolution of a complex scalar field that is known to obey an otherwise unspecified (2+1)-dimensional dissipative nonlinear parabolic d…
