چکیده
We study the influence of fluctuations in periodic motion of boundaries of an ideal three-dimensional cavity on the rate of photon generation from vacuum due to the nonstationary Casimir effect. PACS: 42.50.Lc; 46.40.Ff; 72.80.Ng; 03.65.-w

CO Adsorption on the V (100) Surface: A Density Functional Study
Adsorption of CO molecule on the Vanadium surface has been studied by using of the DFT method with LANL2DZ,6-31G* and 6-31G** basis sets by GGA approximation of theory. Using periodic first principles simulations we investigate the interaction of oxygen molecule with regular V (100) surface. The limitation of this approach is the use of thin metallic slabs with a limited range for their coverag...

Background and Aims : The aim of this study was to evaluate the effect of chlorhexidin 2%, sodium hypochlorite 2.5% and hydrogen peroxide 3% as three effective and regular disinfectants on the microleakage of 7th generation bonding agents in vitro. Materials and Methods: 45 extracted molar teeth without carries were collected and disinfected. On buccal and lingual aspects of these teeth con...
متن کاملTelecom-band degenerate-frequency photon pair generation in silicon microring cavities.
In this Letter, telecom-band degenerate-frequency photon pairs are generated in a specific mode of a silicon microring cavity by the nondegenerate spontaneous four-wave mixing (SFWM) process, under two continuous-wave pumps at resonance wavelength of two different cavity modes. The ratio of coincidence to accidental coincidence is up to 100 under a time bin width of 5 ns, showing their characte...
متن کاملStable nondegenerate optical parametric oscillation at degenerate frequencies in Na:KTP
We report the realization of a light source specifically designed for the generation of bright continuousvariable entangled beams and for Heisenberg-limited inteferometry. The source is a nondegenerate, singlemode, continuous-wave optical parametric oscillator in Na:KTP, operated at frequency degeneracy and just above threshold, which is also of interest for the study of critical fluctuations a...
متن کاملNonstationary Casimir effect in cavities with two resonantly coupled modes
We study the peculiarities of the nonstationary Casimir effect (creation of photons in cavities with moving boundaries) in the special case of two resonantly coupled modes with frequencies ω0 and (3+∆)ω0, parametrically excited due to small amplitude oscillations of the ideal cavity wall at the frequency 2ω0(1 + δ) (with |δ|, |∆| 1). The effects of thermally induced oscillations in time depende...
