We consider the Casimir force betweeen two dielectric bodies described by the plasma model and between two infinitely thin plasma sheets. In both cases in addition to the photon modes surface plasmons are present in the spectrum of the electromagnetic field. We investigate the contribution of both types of modes to the Casimir force and confirm resp. find in both models large compensations betw...

We have recently treated with N2 gas plasma and achieved inactivation of bacteria. However, the effect of N2 gas plasma on viruses remains unclear. With the aim of developing this technique, we analyzed the virucidal effect of N2 gas plasma on influenza virus and its influence on the viral components. We treated influenza virus particles with inert N2 gas plasma (1.5 kpps; kilo pulses per secon...

The aim of this analysis is to search for direct photons, i.e. photons that are not produced in hadron decays such as π → γγ or η → γγ. Direct photons are generally subdivided into prompt photons from initial hard parton scatterings and thermal photons from a possible quark-gluon plasma and from the hadron gas. Prompt photons are produced before a possible quark-gluon plasma has formed. Above a...

I propose an observable to declare the formation of Quark Plasma (QP) without any doubts. It is the observation of Cherenkov photon radiations of the order of 100 MeV associated with fast light charged particles while they are penetrating hot dense mediums produced in high energy heavy ion collisions. Direct observations of Cherenkov rings associated with charged leptons decayed from Z boson or...

I discuss why photon production from the Quark Gluon Plasma (QGP) presents an interesting problem, both experimentally and theoretically. I show how the photon emission rate can be computed under the simplifying assumption that the QGP fully thermalizes. The theoretical issues are very similar to those for jet energy loss; so it should be possible to treat them in a common formalism and relate ...

The Electrostatic Charging Laboratory for Interactions between Plasma and Spacecraft (ECLIPS) research vacuum chamber has recently been developed as part of the Autonomous Vehicle Systems at University Colorado Boulder. experimental spacecraft charging facility allows conducting experiments relevant to charged astrodynamics in a space-like environment. This paper discusses development, characte...

Photon emission arising in the course of transition between the states of quark-gluon and hadron plasma has been considered. Single-photon distributions and two-photon correlations in central rapidity region have been calculated for heavy ion collisions at high energies. It has been found that opposite side two-photon correlations can serve as a sign of sharp transitions between the states of s...

The output spectrum of both gas and semiconductor lasers usually contains more than one frequency. Multimode operation in gas versus semiconductor lasers arises from different physics. In gas lasers, slow equilibration of the electron populations at different energies makes each frequency an independent single-mode laser. The slow electron diffusion in semiconductor lasers, combined with the sp...

The 266 nm light-induced reaction of CO2 and H2O gas mixtures (including isotopic modifications CO2, CO2, and D2O) in framework TiMCM-41 silicate sieve was monitored by in-situ FT-IR spectroscopy at room temperature. Carbon monoxide gas was observed as the sole product by infrared, and the growth was found to depend linearly on the photolysis laser power. H2O was confirmed as stoichiometric ele...
