Cavity-enhanced atom detection with cooperative noise reduction
Cavity-enhanced atom detection cooperative noise reduction
2010/10/20
An optical microcavity with small mode radius is used to measure the local density of a cold
atom cloud. Atom densities below 1 per cavity mode volume are measured with signals near the
photon shot-...
Reply to: Atom gravimeters and the gravitational redshift
Reply Atom gravimeters gravitational redshift
2010/10/26
We stand by our result [1]: The Comment [2] revisits an interesting issue that has been known
for decades, the relationship between test of the universality of free fall and redshift experiments [3–5...
In a recent paper, H. M¨uller, A. Peters and S. Chu [A precision measurement of the gravitational redshift by the interference of matter waves, Nature 463, 926-929 (2010)] argued that atom interferome...
An Experimental Proposal to Test Dynamic Quantum Non-locality with Single-Atom Interferometry
Experimental Proposal Test Dynamic Quantum Non-locality Single-Atom Interferometry
2010/10/19
Quantum non-locality based on the well-known Bell inequality is of kinematic nature. A different type of quantum non-locality, the non-locality of the quantum equation of motion, is recently put forwa...
Hydrogen atom in momentum space with a minimal length
Hydrogen atom momentum space minimal length
2010/10/18
A momentum representation treatment of the hydrogen atom problem with a generalized un-
certainty relation,which leads to a minimal length (Xi)min = ~√3 + ′, is presented. We show that the distanc...
On the analogy between a single atom and an optical resonator
analogy single atom optical resonator
2010/10/19
A single atom in free space can have a strong influence on a light beam and a single photon can have a strong effect on a single atom in free space. Regarding this interaction, two conceptually differ...
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...
Position dependent energy level shifts of an accelerated atom in the presence of a boundary
Position dependent energy level shifts accelerated atom boundary
2010/10/19
We consider a uniformly accelerated atom interacting with a vacuum electromagnetic field in
the presence of an infinite conducting plane boundary and calculate separately the contributions of vacuum ...
A new idea to search for charged lepton flavor violation using a muonic atom
lepton flavor muonic atom
2010/3/16
We propose a new process of mu(-) e(-) -> e(-) e(-) in a muonic atom for a quest of charged lepton flavor violation. The Coulomb attraction from the nucleus in a heavy muonic atom leads to significant...
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...

2010/4/2
We demonstrate, through numerical simulations, the emission of a coherent continuous matter wave of constant amplitude from a Bose-Einstein Condensate in a shallow optical dipole trap. The process is ...
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...

2010/3/10
We investigate spectral properties of the atomic fluorescence and the output field of the cavity-mode of a single-atom dressed-state laser in a photonic crystal. We pay a particular attention to the b...

Cold atom scattering cavity fields two-dimensional geometry
2010/3/10
The quantum theory of the cold atom scattering by cavity fields in a two-dimensional geometry is presented. A distinct regime from the usual Raman-Nath, Bragg and Stern-Gerlach regimes is investigated...
Interaction and chaotic dynamics of the classical hydrogen atom in an electromagnetic field
classical hydrogen atom electromagnetic field angular momentum
2010/4/1
Expressions for energy and angular momentum changes of the hydrogen atom due to interaction with the electromagnetic field during the period of the electron motion in the Coulomb field are derived. It...
