Plasma Modulation of Harmonic Emission Spectra from Laser-Dense Plasma Interactions

We report results from PIC simulations of the interaction of intense laser light with overdense plasma designed to examine the effects of plasma waves generated by pulses of fast electrons on high harmonic emission from the plasma. We show that the emission spectrum is modulated at the plasma frequency and identify combinations of parameters and circumstances favourable for modulation. In parti...

Randomly inhomogeneous Luttinger liquid : Fluctuations of the tunnel conductance

Randomly inhomogeneous Luttinger liquid: Fluctuations of the tunnel conductance. Abstract The Luttinger liquid in which the concentration of electrons varies randomly with coordinate is considered. We study the fluctuations of the tunnel conductance, caused by the randomness in the concentration. If the concentration changes slowly on the scale of the Fermi wavelength, its prime role reduces to...

Emission altitude in radio pulsars

This paper presents a method of estimation of emission altitudes using observational data-precise measurements of pulse profile widths at low intensity level. The analysis of emission altitudes obtained using this method for a large number of pulsars gives constraints that should be useful for theory of coherent pulsar emission. It seems that radio emission originates at altitudes of about few ...

Radio Emission from Algol

We report dual circular polarization VLBA observations of Algol made at orbital phases 0.22{0.30 using a diierential phase referencing technique. The ux density of Algol varied from 10{20 mJy during the observations. The radio maps show a double-lobe source separated by 1.6 mas (1.4 times the K star diameter). Although the total emission is only weakly circularly polarized, the individual lobes...
