Plasmas have been recently studied as topological materials. However, a comprehensive picture of phases and phase transitions in cold magnetized plasmas is still missing. Here we systematically map out all the establish bulk-edge correspondence plasmas. We find that for linear eigenmodes, there are 10 parameter space density $n$, magnetic field $B$, parallel wavenumber $k_{z}$, separated by sur...

The expansion of a dense (initially, n(lpp)/n(0)>>1) laser-produced plasma into an ambient magnetized plasma ( n(0) = 2 x 10(12) cm(-3)) capable of supporting Alfvén waves has been studied. The interaction results in the production of shear Alfvén waves as well as large density perturbations (Delta n/n(0) approximately 0.3) associated with the moving dense plasma. The waves propagate away from ...

The transmission of electromagnetic waves across a thin plasma layer whose width is comparable to the wavelength of an incident wave is studied. The transmittances of transverse electric and transverse magnetic modes for both underdense and overdense plasmas are obtained as a function of the angle of incidence. It is thought that the significant reduction of transmittance in overdense plasma’s ...

By applying a helical electric field along a plasma region, a revolving electron current is formed along the plasma and an elliptically polarized far-field terahertz wave pattern is observed. The observed terahertz wave polarization reveals the remarkable role of velocity retardation between optical pulses and generated terahertz pulses in the generation process. Extensive simulations, includin...

An experiment on phase-locked injection of ~ 100 fs electron bunches in a plasma beat wave accelerator is presented. We consider using an IFEL microbunching technique to produce ultrashort electron bunches prebunched at the exact wavelength of the plasma wave 340 Jim (~lTHz). It is proposed to generate 100 MW of 1 THz radiation by difference frequency generation in a nonlinear crystal, mixing t...

We show both theoretically and experimentally that an electromagnetic wave can be totally absorbed by an overdense plasma when a subwavelength diffraction grating is placed in front of the plasma surface. The absorption is due to dissipation of surface plasma waves (plasmons polaritons) that have been resonantly excited by the evanescent component of the diffracted electromagnetic wave. The dev...

The authors develop a theory of photodetection in double-gated bilayer graphene (BLG) field-effect transistor (FET), following the Dyakonov-Shur scheme based on nonlinear mixing plasma waves. A BLG channel displays peculiar effect: band gap depends intensity wave, which makes photoresponse dependent FET electrostatics. work here bridges microscopic features electronic dispersion two-dimensional...

Transmittance of electromagnetic waves with normal incidence in one-dimensional plasma photonic crystals is studied numerically based on the invariant imbedding method. Wave transmittance as a function of wave frequency shows the appearance of forbidden band gaps, which are conspicuous in photonic crystals. We also demonstrate that the small modification of plasma photonic crystal leads to diff...
