Entanglement of Two Atoms using Rydberg Blockade [PDF]

open access: yesAdv. At. Mol. Opt. Phys. 61, 81 (2012), 2012
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 review the basic physics involved in this process: loading of single atoms into individual traps, state initialization, state readout, single atom rotations,

Atomic physics and modern solar spectro-polarimetry

open access: yes, 2017
Observational solar physics is entering a new era with the advent of new 1.5 m class telescopes with adaptive optics, as well as the Daniel K. Inouye 4 m telescope which will become operational in 2019.

Study of the compression behavior and high-pressure strength of a-Si3N4 combining experimental and theoretical methods

open access: yesAIP Advances, 2019
The compression behavior and high-pressure strength of alpha silicon nitride (α-Si3N4) at pressures of up to 60 GPa are studied using synchrotron radiation powder diffraction, complemented with first-principles calculations.

Stimulated Enhancement of Cross-Section by a Bose-Einstein Condensate [PDF]

open access: yes, 1996
This paper examines the feasibility of constructing an experiment which detects the atomic stimulation of a photon emission process. A beam of atoms (bosons) in an excited state is passed over an atomic trap which traps the atoms when they are in their internal ground state.

Quantum Many-Body Phenomena in Coupled Cavity Arrays

open access: yes, 2008
The increasing level of experimental control over atomic and optical systems gained in the past years have paved the way for the exploration of new physical regimes in quantum optics and atomic physics, characterised by the appearance of quantum many ...

A simple scaling law between the total energy of a free atom and its atomic number [PDF]

open access: yesarXiv, 1999
A simple, approximate relation is found between the total energy of a free atom and its atomic number: E ~= -Z^{2.411}. The existence of this index is inherent in the Coulomb and many-body nature of the electron-electron interaction in the atomic system and cannot be fabricated from the existing fundamental physical constants.

Meson and Quark Degrees of Freedom and the Radius of the Deuteron [PDF]

open access: yes, 1996
The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic physics experiment.

Evolution of water dynamics in the Prussian blue

open access: yesEPJ Web of Conferences, 2015
Crystal water plays a crucial role towards the multifunctional properties of Prussian blue and its analogue (PBA) compounds. We have investigated the dynamics of crystal water in Prussian blue (PB), Fe(III)4[Fe(II)(CN)6]3.

On the origin of the gravitational quantization: The Titius--Bode Law

open access: yes, 2005
Action at distance in Newtonian physics is replaced by finite propagation speeds in classical post--Newtonian physics. As a result, the differential equations of motion in Newtonian physics are replaced by functional differential equations, where the ...

Resonantly enhanced photoionization in correlated three-atomic systems [PDF]

open access: yes, 2012
Modifications of photoionization arising from resonant electron-electron correlations between neighbouring atoms in an atomic sample are studied. The sample contains atomic species A and B, with the ionization potential of A being smaller than the energy of a dipole-allowed transition in B.
