Dynamic failure by adiabatic shear banding

Abstract This paper addresses adiabatic shear localization from a different point of view. New results are reviewed which indicate$backslash$nthat the process can be viewed as triggered by dynamic recrystallization instead of being the result of …

Fingerprints of classical chaos in manipulation of cold atoms in the dynamical tunneling experiments

The recent pioneering experiments of the [Nature 412, 52 (2001)] and [Science, 293, 274 (2001)] groups have demonstrated the dynamical tunneling of cold atoms interacting with standing electromagnetic waves. It has been shown [Phys. Rev. Lett. 89, …

Controlled tunneling of cold atoms: from full suppression to strong enhancement.

Two recent experiments have demonstrated the phenomenon of dynamical tunneling of cold atoms interacting with standing electromagnetic waves. We show by quantitative calculations that one can achieve a control of the tunneling period over an orders …
