In this talk, I will report some recent progress regarding wave scattering problems in anisotropic media.
In the quest for fusion energy, understanding how radio-frequency (RF) waves travel (or “propagate”) in the turbulent interior of a fusion furnace is crucial to maintaining an efficient, continuously ...
Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Circular Sound Wave Scattering Derivation Acoustic Cloak Detection Classical Physics
2012/5/29
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is reflectionless and ...
Nonlinear Bose-Einstein-condensate Dynamics Induced by a Harmonic Modulation of the s-wave Scattering Length
Nonlinear Bose-Einstein-condensate Dynamics Induced Harmonic Modulation the s-wave Scattering Length
2011/9/15
In a recent experiment, a Bose-Einstein condensate of 7Li has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an analytical perturbati...
Dynamical charge and spin density wave scattering in cuprate superconductor
Dynamical charge spin density wave cuprate superconductor
2010/11/19
We show that a variety of spectral features in high-Tc cuprates can be understood from the coupling of charge carriers to some kind of dynamical order which we exemplify in terms of fluctuating charge...
s-wave scattering and the zero-range limit of the finite square well in arbitrary dimensions
s-wave scattering zero-range limit finite square arbitrary dimensions
2010/10/19
We examine the zero-range limit of the finite square well in arbitrary dimensions through a systematic analysis of the reduced, s-wave two-body time-independent Schr¨odinger equation. A natural conseq...
