If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the m...
Piezoelectrically-actuated time-averaged atomic microtraps
atomic microtraps Atomic Physics
2012/5/17
We present a scheme for creating tight and adiabatic time-averaged atom-traps through the piezoelectric actuation of nanomagnetic structures. We show that potentials formed by the circular translation...

Study of Simulation Method Time Evolution Rigged QED Atomic Physics
2012/4/20
We discuss how we formulate time evolution of physical quantities in the framework of the Rigged QED (Quantum Electrodynamics). The Rigged QED is a theory which has been proposed to treat dynamics of ...
Causality and quantum interference in time-delayed laser-induced nonsequential double ionization
Causality quantum interference time-delayed laser-induced nonsequential double ionization

Abstract: We perform a detailed analysis of the importance of causality within the strong-field approximation and the steepest descent framework for the recollision-excitation with subsequent tunnelin...
Time scaling with efficient time-propagation techniques for atoms and molecules in pulsed radiation fields
Time scaling atoms and molecules pulsed radiation fields

We present an ab initio approach to solve the time-dependent Schrodinger equation to treat electron and photon impact multiple ionization of atoms or molecules. It combines the already known time sca...
Streaking and Wigner time delays in photoemission from atoms and surfaces
Streaking Wigner photoemission atoms and surfaces
2011/9/13
Streaked photoemission metrology allows the observation of an apparent relative time delay between the detection of photoelectrons from different initial electronic states. This relative delay is obta...

Realistic Time-Reversal Invariant Topological Neutral Atoms
2010/11/23
We lay out an experiment to realize time-reversal invariant topological insulators in alkali atomic gases. We introduce an original method to synthesize a gauge field in the near-field of an atom-chip...
Constraining the mixing matrix for Standard Model with four generations: time dependent and semi-leptonic CP asymmetries in $B_d^0$, $B_s$ and $D^0$
