Many-body effects for excitonic high-order wave mixing in monolayer transition metal dichalcogenides
Publikováno v:
Physical Review Research, Vol 2, Iss 2, p 023072 (2020)
A microscopic quantum theory describing the nonlinear and nonperturbative optical response of monolayer transition metal dichalcogenides (MTMDs) to a two-color strong laser field is developed within the dynamical Hartree-Fock approximation. Taking in

We consider nonlinear interaction of superpower laser pulses of relativistic intensities with nanolayers and solid-plasma targets toward the production of high energy-density electron and positron bunches along with high energy photon fluxes. It is s

A method for generation of quasimonoenergetic, low emittance fast ion/nuclei bunches of solid densities from nanotargets by two counterpropagating laser pulses of ultrarelativistic intensities is proposed, based on the threshold phenomenon of particl

The nonlinear threshold phenomena of particle reflection and capture of electrons in the induced Compton process that have previously been revealed in the case of plane monochromatic counterpropagating waves, take place also with the actual nonplane

Laser acceleration due to the nonlinear-threshold phenomena of charged particle “reflection” and capture by slowed wave in a magnetic undulator is considered. The obtained numerical results prove the particle reflection and capture phenomena in t

The charged particles nonlinear dynamics in the field of a strong electromagnetic wave pulse of finite duration and certain form of the envelope, in the refractive medium with a constant and variable refraction indexes, is investigated by means of nu

In this work we consider in general the high-gain SASE x-ray Compton FEL in the quantum regime of amplification arising from the self-consistent set of the Maxwell and relativistic quantum kinetic equations. The analytical solutions are obtained whic

We consider coherent dynamics of graphene charged carriers exposed to an intense few-cycle linearly polarized laser pulse. The results, obtained by solving the generalized semiconductor Bloch equations numerically in the Hartree-Fock approximation, t
