We theoretically study the low-energy scattering of ultracold atoms by a dielectric nanosphere silica glass levitated in vacuum. The atom and surface interact via dispersion force which strength sensitively depends on polarizability, function, geometry. For cesium rubidium atoms, respectively, we compute atom-surface interaction characterize stationary states taking adsorption onto into account...

A nanoscale object evidenced in a non-classical state of its centre mass will hugely extend the boundaries quantum mechanics. To obtain practical scheme for same, we exploit hitherto unexplored coupled system: an atom and nanoparticle by optical field. We show how to control center-of-mass large $\sim500$nm using internal so as create, well detect, nonclassical motional states nanoparticle. Spe...

In this Letter, stabilizing a Faraday laser frequency to the atomic transition is proposed and experimentally demonstrated, where can work at single- or dual-frequency modes. High-resolution spectroscopy of cesium atom induced by obtained. By with spectroscopy, fluctuations are suppressed without need high-cost Pound–Drever–Hall system. The fractional Allan deviation residual error signal 3 × 1...

Radioactive cesium (137Cs) has inevitably become a human concern due to exposure from nuclear power plants and nuclear accident releases. Many efforts have been focused on removing cesium and the remediation of the contaminated environment. In this study, we elucidated the ability of Prussian blue-coated magnetic nanoparticles to eliminate cesium from radioactive contaminated waste. Thus, the o...

Giant axons from the squid were injected with 1.5 M cesium sulfate solutions containing the radioactive isotopes 42K and 134Cs. These axons, when stimulated, gave characteristic long duration action potentials lasting between 5 and 45 msec. The effluxes of 42K and 134Cs were measured both under resting conditions and during periods of repetitive stimulation. During the lengthened responses ther...

MicroRNAs (miRNAs) are short RNA fragments that play important roles in controlled gene silencing, thus regulating many biological processes in plants. Recent studies have indicated that plants modulate miRNAs to sustain their survival in response to a variety of environmental stimuli, such as biotic stresses, cold, drought, nutritional starvation, and toxic heavy metals. Cesium and radio-cesiu...

We investigate the use of a split-ring resonator (SRR) incorporated with an atomic-vapor cell to improve sensitivity and minimal detectable electric (E) field Rydberg atom-based sensors. In this approach, sub-wavelength SRR is placed around atomic vapor-cell filled cesium atoms for E-field measurements at 1.3 GHz. The provides factor 100 in enhancement measurement sensitivity. Using electromagn...

We describe a cold atom clock designed for operating in micrograv@, the PHARAO project. Preliminary resulfs have a W y been obtained on earth and the prototJpe wil l be Wed in the reduced g r a v e of aircrajl parabolic flights in the beginning of 1997. The PHARAO prototype i s an extension of the work done at the BNM-LPTF on a cesium atomic fountain, which presents a resonance linewidth of 700...

The electron-stimulated desorption (ESD) yields and energy distributions for potassium (K) and cesium (Cs) atoms have been measured from K and Cs layers adsorbed at 300 K on oxidized molybdenum surfaces with various degrees of oxidation. The measurements were carried out using a time-of-flight method and surface ionization detector. The ESD appearance threshold for K and Cs atoms is independent...

The study examines the transfer factor (TF) for cesium in a soil-plant system and cesium accumulation in cress Lepidium sativum L. plants grown in hydroponic culture and subjected to root and foliar application of 0.3 mM CsCl. The experiments showed a high TF for radiocesium: 2.97 (kBq/kg plant DW)/(kBq/kg soil DW). High accumulation of cesium was observed in leaves after both root and foliar t...
