We study the optomechanical coupling of a oscillating effective mirror with a Rydberg atomic gas, mediated by the dynamical atom-mirror Casimir-Polder force. This coupling may produce a near-field resonant atomic excitation whose probability scales as ∝(d(2)an(4)t)(2)/z(0)(8), where z(0) is the average atom-surface distance, d the atomic dipole moment, a the mirror's effective oscillation ampli...

Two months of spaceborne POLDER polarization measurements have been used to generate empirical surface bidirectional polarization distribution functions (BPDF’s). Eleven surface classes have been defined based on a surface classification and a vegetation index. Within each class, the surface polarized reflectance was found rather homogeneous. The surface polarized reflectance is highly anisotro...

We present an explicit analytic calculation of the energy-level shift of an atom in front of a nondispersive and nondissipative dielectric slab. We work with the fully quantized electromagnetic field, taking retardation into account. We give the shift as a two-dimensional integral and use asymptotic analysis to find expressions for it in various retarded and nonretarded limiting cases. The resu...

Integrating out virtual quantum fluctuations in an originally local quantum field theory results in an effective theory which is non-local. In this Letter we argue that tunnelling of the 3rd kind — where particles traverse a barrier by splitting into a pair of virtual particles which recombine only after a finite distance — provides a direct test of this non-locality. We sketch a quantum-optica...

The measurement of deuteron tensor polarization using (e, d) elastic scattering was performed in Hall C, Jefferson Lab by the t20 collaboration at four-momentum transfers of 4.10, 4.46, 5.08, 5.48, 6.23 and 6.65 fm 1 . The scattered electrons were detected by the High Momentum Spectrometer, and a specially designed magnetic channel was used to detect deuterons in coincidence. The polarization o...

PM 10 remote sensing is of great significance in the atmospheric environment studies. Contrary to intuitive perception, deriving more difficult than 2.5 from satellite measurements. This because although major parameter Aerosol Optical Depth (AOD) contain contribution all suspended particles, it much sensitive fine particles coarse particles. To address this challenge, a physically based method...

The ‘polder model’ strategy of the nature conservation movement in Netherlands, 1930-1960 This article analyses strategies applied by early Netherlands to exert influence at political level. Before 1970s, conservationist civil society organisations preferred informal deals, advisory committees, and negotiated agreements with government departments state agencies. It is argued that balance betwe...
