Adaptive Q control for Tapping-mode Nano-scanning Using a Piezo-actuated Bimorph Probe
Adaptive Q control Tapping-mode Nano-scanning Piezo-actuated Bimorph Probe Atomic Physics
2012/4/24
A new approach, called Adaptive Q-control, for tapping-mode Atomic Force Microscopy (AFM) is introduced and implemented on a home-made AFM set-up utilizing a Laser Doppler Vibrometer (LDV) and a piezo...
Storage and Retrieval of an Image using Four-Wave Mixing in a Cold Atomic Ensemble
Storage Retrieval of an Image Four-Wave Mixing Cold Atomic Ensemble
2012/4/19
We experimentally realized storage and retrieval of an image of light in a cigar-shaped atomic cloud of Rubidium 85 using four-wave mixing (FWM) for the first time. The input signal and the generated ...
Laser stabilization to an atomic transition using an optically generated dispersive lineshape
Laser stabilization atomic transition optically generated dispersive lineshape Atomic Physics
2012/4/19
We report on a simple and robust technique to generate a dispersive signal which serves as an error signal to electronically stabilize a monomode cw laser emitting around an atomic resonance. We explo...

Modeling core-hole screening jellium clusters density functional theory
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...
Over the past few years we have built an apparatus to demonstrate the entanglement of neutral Rb atoms at optically resolvable distances using the strong interactions between Rydberg atoms. Here we re...

2011/8/4
Abstract: A theoretical approach is described for an exact numerical treatment of a pair of ultracold atoms interacting via a central potential that are trapped in a finite three-dimensional optical l...
In this work we investigate small clusters of helium atoms using the hyperspherical harmonic basis. We consider systems with A = 2, 3, 4, 5, 6 atoms with an inter-particle potential which does not pre...
Electrometry near a dielectric surface using Rydberg electromagnetically induced transparency
Rydberg electromagnetically induced Electrometry
2011/9/2
Electrometry near a dielectric surface is performed using Rydberg electromagnetically induced transparency (EIT). The large polarizability of high n-state Rydberg atoms gives this method extreme sensi...
Molecular imaging using high-order harmonic generation and above-threshold ionization
above-threshold high-order harmonic
2011/9/1
Accurate molecular imaging via high-order harmonic generation relies on comparing the harmonic emission from a molecule and an adequate reference system. However, an ideal reference atom with the same...
A new limit on Lorentz-violating tensor interactions set using $^{21}$Ne-Rb-K comagnetometer
Lorentz-violating 21Ne-Rb-K comagnetometer
2011/8/29
We develop a comagnetometer using 21Ne atoms with nuclear spin I = 3=2 and Rb atoms polarized by spin-exchange with K atoms to search for tensor interactions that violate local Lorentz invariance.We f...

2010/11/16
We present a proof-of-principle experiment in which the population of an atomic level is spatially localized using the technique of electromagnetically-induced transparency (EIT). The key idea is to ...
Coherent control of atomic excitation using off-resonant strong few-cycle pulses
Coherent control atomic excitation off-resonant strong few-cycle pulses
2010/11/9
We study the dynamics of a two-level system driven by an off-resonant few-cycle pulse which has a phase jump $\phi$ at $t=t_{0}$, in contrast to many cycle pulses, under non rotating-wave approximati...
