ATOMIC ENERGY—HOW BIG THE FIELD?

“Big Data”: Big Gaps of Knowledge in the Field of Internet Science

As a member of the editorial board and editors of the International Journal of Internet Science we would like to take this opportunity to comment on some interesting developments in the field of Internet science and Web science. The analysis of so-called “Big Data” has received a remarkable momentum. Conducting a search with “Big Data” as a query, we find 130 entries in the ISI Web of Science, ...

Magnetic field imaging with atomic Rb vapor.

We demonstrate the possibility of dynamic imaging of magnetic fields using electromagnetically induced transparency in an atomic gas. As an experimental demonstration we employ an atomic Rb gas confined in a glass cell to image the transverse magnetic field created by a long straight wire. In this arrangement, which clearly reveals the essential effect, the field of view is about 2 x 2 mm(2) an...

Atomic Radiative Transitions in Thermo Field Dynamics

In this work we study the energy exchange between an atomic system and a thermal radiation field, using the Dalibard, Dupont-Roc and Cohen-Tannoudji (DDC) construct, incorporating temperature effects to the eigenstates of the radiation field operator through the electromagnetic propagator of Thermo Field Dynamics in the Coulomb gauge. We also discuss the stability of the atomic system at finite...

Field Theory for Trapped Atomic Gases

Atomic Response in the Near-Field of Nanostructured Plasmonic Metamaterial.

We report on reflection spectra of cesium atoms in close vicinity of a nanostructured metallic meta-surface. We show that the hyperfine sub-Doppler spectrum of the 6(2)S1/2-6(2)P3/2 resonance transition at 852 nm is strongly affected by the coupling to the plasmonic resonance of the nanostructure. Fine tuning of dispersion and positions of the atomic lines in the near-field of plasmonic metamat...
