Transition Radiation of Moving Abrikosov Vortices [PDF]
We show that Abrikosov vortices moving towards the surface of a superconductor emit electromagnetic radiation into free space. The frequency distribution of the radiated intensity displays a pronounced maximum at microwave frequencies around v_x/lambda ...

Quantum theory of transition radiation and transition pair creation [PDF]
Theory of the transition radiation and the transition pair creation is developed in the frame of QED. The spectral-angular distributions of probability of the transition radiation and of the transition pair creation are found.

Enhanced coherent transition radiation from midinfrared-laser-driven microplasmas [PDF]
We present a particle-in-cell (PIC) analysis of terahertz (THz) radiation by ultrafast plasma currents driven by relativistic-intensity laser pulses.

Transition Radiation by Neutrinos [PDF]
We calculate the transition radiation process $\nu \to \nu \gamma$ at an interface of two media. The neutrinos are taken to be with only standard-model couplings. The medium fulfills the dual purpose of inducing an effective neutrino-photon vertex and of

Foam radiators for transition radiation detectors [PDF]
Abstract A wide variety of foam radiators, potentially useful in the design of a transition radiation detector, the possible particle identification tool in collider experiments, have been tested in the beam. Various characteristics of these radiators are compared, and the conclusion is reached that certain brands of polyethylene foam are best suited

Free-electron Brewster-transition radiation. [PDF]
We reveal a mechanism to enhance particle-matter interactions by exploiting the pseudo-Brewster effect of gain materials, presenting an enhancement of at least four orders of magnitude for light emission. This mechanism is enabled by the emergence of an unprecedented phase diagram that maps all phenomena of free-electron transition radiation into three

Transition radiation and the origin of sonoluminescence [PDF]
It has been shown by Liberati et al. [quant-ph/9904013] that a dielectric medium with a time-dependent refractive index may produce photons. We point out that a free electric charge which interacts with such a medium will emit quantum mechanically modified transition radiation in which an arbitrary odd number of photons will be present.

Gamma Ray Cherenkov-Transition Radiation [PDF]
The production of gamma-ray Cherenkov-transition radiation (GCTR) by charged particles in the photon energy region 0.8 - 2 MeV is studied theoretically using the results of the recent discovery that in the above mentioned region the dielectric constant ...

Radio-Frequency Measurements of Coherent Transition and Cherenkov Radiation: Implications for High-Energy Neutrino Detection [PDF]
We report on measurements of 11-18 cm wavelength radio emission from interactions of 15.2 MeV pulsed electron bunches at the Argonne Wakefield Accelerator.

Transition radiation in mechanics [PDF]
Transition radiation of elastic waves generated by a mechanical object that performs a uniform rectilinear motion along an inhomogeneous elastic system (a string, beam, membrane, or plate) is discussed in detail. The effect is analysed by assuming that the law of motion of the load admits the generation of neither Cherenkov nor bremsstrahlung radiation,
