Sound waves and modulational instabilities on continuous wave solutions in spinor Bose-Einstein condensates
Richard S. Tasgal, Y. B. Band
We analyze sound waves (phonons, Bogoliubov excitations) propagating on continuous wave (cw) solutions of repulsive spinor Bose-Einstein condensates (BECs), such as Na…
Continuous wave solutions in spinor Bose-Einstein condensates
Richard S. Tasgal, Y. B. Band
We find analytic continuous wave (cw) solutions for spinor Bose-Einstein condenates (BECs) in a magnetic field that are more general than those published to date. For particles wit…
Creating very slow optical gap solitons with inter-fiber coupling
R. Shnaiderman, Richard S. Tasgal, Y. B. Band
We show that gap-acoustic solitons, i.e., optical gap solitons with electrostrictive coupling to sound modes, can be produced with velocities down to less than 2.5% of the speed of…
Optoacoustic solitons in Bragg gratings
Richard S. Tasgal, Y. B. Band, Boris A. Malomed
Optical gap solitons, which exist due to a balance of nonlinearity and dispersion due to a Bragg grating, can couple to acoustic waves through electrostriction. This gives rise to…
Highly Nonlinear Dynamics of Third-Harmonic Generation by Focused Beams
Richard S. Tasgal, Marek Trippenbach, M. Matuszewski +1
Beams that experience third-harmonic generation (THG) also experience Kerr effects. With Kerr effects, beams do not take simple Gaussian shapes, but exhibit nonlinear dynamics. The…
