Ultracold atom waves may shed light on rogue ocean killers
Ultracold atom waves shed light rogue ocean killers
2017/7/19
By precisely controlling the quantum behavior of an ultracold atomic gas, Rice University physicists have created a model system for studying the wave phenomenon that may bring about rogue waves in Ea...
Electron-atom bremsstrahlung: double differential cross section and polarization correlations
Electron-atom bremsstrahlung double differential cross section polarization correlations
2010/11/16
The leading-order electron-atom bremsstrahlung is investigated within the rigorous relativistic approach based on the partial-wave representation of the Dirac wave functions in the external atomic fi...
We determine the energy-level shift experienced by a neutral atom due the quantum electromagnetic interaction with a layered dielectric body. We use the technique of normal-mode expansion to quantize...
Variational and perturbative approaches to the confined hydrogen atom with a moving nucleus
Variational perturbative approaches confined hydrogen atom moving nucleus
2010/10/19
We calculate the ground–state energy and other physical properties of the hydrogen atom inside a spherical box with an impenetrable wall. We apply the variational method and perturbation theory and co...
Cold-atom induced control of an opto-mechanical device
Cold-atom induced control opto-mechanical device
2010/3/10
We consider an optical cavity with a light vibrating end-mirror and containing a Bose-Einstein condensate (BEC). The mediation of the cavity field induces a non-trivial interplay between the mirror an...
Antihydrogen formation dynamics in a multipolar neutral anti-atom trap
Antihydrogen CPT Non-Neutral Plasma Particle Transport
2010/3/15
Antihydrogen production in a neutral atom trap formed by an octupole-based magnetic field minimum is demonstrated using field-ionization of weakly bound anti-atoms. Using our unique annihilation imagi...
We obtained the coherent states for the hydrogen atom by transforming the problem onto the four oscillators in the parametric time at the classical level and quantizing these oscillators. We showed th...
