Light pressure of isotropic radiation from relic to extreme relativistic temperatures
نویسنده
چکیده
A fully relativistic/QED theory of light pressure of an isotropic, in particular relic, radiation yields analytic results in the momentum decay of an electron over entire span of energies in the universe. Using a FokkerPlanck-like equation, the evolution of initial extremely-high-T electron distribution to low-energy spectral line is analytically obtained for momentum span over tens orders of magnitude. A strong imprint of low-T relic radiation on high-energy spectral distribution transpires via formation of a “frozen non-equilibrium” state of electrons in current epoch, and possible existence of narrow spectral lines as remnants of past high-T sources.

متن کاملFully QED/relativistic theory of light pressure on free electrons by isotropic radiation
A relativistic/QED theory of light pressure on electrons by an isotropic, in particular blackbody radiation predicts thermalization rates of free electrons over entire span of energies available in the lab and the nature. The calculations based on the QED Klein-Nishina theory of electron-photon scattering and relativistic Fokker-Planck equation, show that the transition from classical (Thompson...

We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed.

متن کاملRelativistic electron mirrors from nanoscale foils for coherent frequency upshift to the extreme ultraviolet
Reflecting light from a mirror moving close to the speed of light has been envisioned as a route towards producing bright X-ray pulses since Einstein's seminal work on special relativity. For an ideal relativistic mirror, the peak power of the reflected radiation can substantially exceed that of the incident radiation due to the increase in photon energy and accompanying temporal compression. H...

The number of studies on extremophilic organisms has grown exponentially in the last few years. These exotic organisms (extremoplilees) are adapted to living at 100 c. In volcanic springs, at low temperatures in the cold polar seas, at high pressure in the deep sea, at very low and high ph values (ph 0-1 or ph 10-11) or at hight salt concentration (35%). Recent developments clearly show that ce...
