Under-the-barrier dynamics laser-induced relativistic tunneling Atomic Physics
2012/5/29
The tunneling dynamics in relativistic strong-field ionization is investigated with the aim to develop an intuitive picture for the relativistic tunneling regime. We demonstrate that the tunneling pic...

Long timescale dynamics spin textures Rb spinor Bose gas
2011/8/17
Abstract: We investigate the long-term dynamics of spin textures prepared by cooling unmagnetized spinor gases of F=1 $^{87}$Rb to quantum degeneracy, observing domain coarsening and a strong dependen...
Optical Excitation and Decay Dynamics of Ytterbium Atoms Embedded in a Solid Neon Matrix
Ytterbium Atoms Embedded Optical Excitation and Decay Dynamics
2011/9/2
Neutral ytterbium atoms embedded in solid neon qualitatively retain the structure of free atoms. Despite the atom-solid interaction, the 6s6p 3P0 level is found to remain metastable with its lifetimes...
Static and dynamic contributions to anomalous chain dynamics in polymer blends
Static dynamic contributions anomalous chain dynamics polymer blends
2010/11/19
By means of computer simulations, we investigate the relaxation of the Rouse modes in a simple bead-spring model for non-entangled polymer blends. Two different models are used for the fast component,...
Generation and Dynamics of Quantized Vortices in a Unitary Fermi Superfluid
Generation Dynamics of Quantized Vortices Unitary Fermi Superfluid
2011/1/10
Superfluidity and superconductivity are remarkable manifestations of quantum coherence at a macroscopic scale. The dynamics of superfluids has dominated the study of these systems for decades now, but...
