Dynamics of hydrogen-like atom bounded by maximal acceleration
Maximal acceleration Extended Relativistic Dynamics Hydrogen-like atom probabilistic description center of mass
2012/4/20
The existence of a maximal acceleration for massive objects was conjectured by Caianiello 30 years ago based on the Heisenberg uncertainty relations. Many consequences of this hypothesis have been stu...
Quantum Incompressibility of a Freely Falling Hydrogen Atom in a Circular Rydberg State, and a Gravitationally-Induced Charge Separation Effect in Superconducting Systems
Quantum Incompressibility Gravitationally-Induced Charge Separation Effect Superconducting Systems
2010/11/8
Freely falling point-like objects converge toward the center of the Earth. Hence the gravitational field of the Earth is inhomogeneous, and possesses a tidal component. The free fall of an extended qu...
Observation of quantum jumps in a superconducting artificial atom

2010/10/27
We continuously measure the state of a superconducting quantum bit coupled to a microwave
readout cavity by using a fast, ultralow-noise parametric ampli er. This arrangement allows us to observe qua...
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...
Quantum jumps and spin dynamics of interacting atoms in a strongly coupled atom-cavity system
Quantum jumps spin dynamics atoms strongly coupled atom-cavity system
2010/4/9
We experimentally investigate the spin dynamics of one and two neutral atoms strongly coupled to a high finesse optical cavity. We observe quantum jumps between hyperfine ground states of a single ato...
Intensity-field correlation of single-atom resonance fluorescence
Intensity-field single-atom resonance fluorescence
2010/4/9
We report measurements of an intensity-field correlation function of the resonance fluorescence of a single trapped Ba+ ion. Detection of a photon prepares the atom in its ground state and we observe ...
Properties of a two-level atom coupled to the quantized electromagnetic field at finite temperature are determined. The analysis is based on a new method (inspired by QED) of describing qubits, develo...

2010/4/7
We study a Fabry-Perot cavity formed from a ridge waveguide on a AlGaAs substrate. We experimentally determined the propagation losses in the waveguide at 780 nm, the wavelength of Rb atoms. We have a...
Fully quantum-mechanical analytic results for single-photon transport in a single-mode waveguide coupled to a whispering-gallery resonator interacting with a two-level atom
quantum-mechanical analytic single-photon single-mode waveguide whispering-gallery resonator a two-level atom
2010/4/9
We analyze the single-photon transport in a single-mode waveguide coupled to a whispering-gallery-type resonator interacting with a two-level atom. The single-photon transport properties such as the t...

single-photon transport a single-mode waveguide two-level atom
2010/4/9
The single-photon transport in a single-mode waveguide, coupled to a cavity embedded with a two-leval atom is analyzed. The single-photon transmission and reflection amplitudes, as well as the cavity ...

Feshbach ultracold atom-molecule collisions
2010/4/9
We investigate the presence of Feshbach resonances in ultracold alkali-dialkali reactive collisions. Quantum scattering calculations are performed on a new Na_3 quartet potential energy surface. An an...
Efficient routing of single photons by one atom and a microtoroidal cavity
single photons atom microtoroidal cavity
2010/4/8
Single photons from a coherent input are efficiently redirected to a separate output by way of a fiber-coupled microtoroidal cavity interacting with individual Cesium atoms. By operating in an overcou...
