Dynamical Instability of a Two Component Bose-Einstein Condensate in an Optical Lattice
(2006)
We investigate the dynamical instability for a two component Bose-Einstein Condensate (BEC) in an optical lattice. We assume that the two components are in sinusoidal potentials with the same period but different phases. ...
Creation of A Vortex in A Bose-Einstein Condensate By Superradiant Scattering
(2011)
The creation of a topological vortex by a superradiant scattering of a Laguerre-Gaussian (LG) beam off an atomic Bose-Einstein condensate (BEC) is theoretically investigated. It is shown that scattered superradiant radiation ...
Metal nanoparticle plasmons operating within a quantum lifetime
(Royal Soc Chemistry, 2013)
We investigate the dynamics of a plasmonic oscillation over a metal nanoparticle when it is strongly coupled to a quantum emitter (e.g. quantum dot, molecule). We simulate the density matrix evolution for a simple model, ...
Testing the reliability of a velocity definition in a dispersive medium
(Amer Physical Soc, 2012)
We introduce a method to test if a given velocity definition corresponds to an actual physical flow in a dispersive medium. We utilize the equivalence of the pulse dynamics in the real-omega and real-k Fourier expansion ...
