Influence of a strong electromagnetic wave on stimulated bremsstrahlung of electrons

Abstract

Superfield methods can be used to determine the precise way the self-dual fiveform couples to the metric in the first non-trivial α ′ corrections to type IIB supergravity. We explicitly compute the exact tensor structure of these terms. This requires extensive use of computing algorithms to reduce the complicated expressions that appear to a surprisingly simple form. Along the way we show a new method of computing Schouten identities. With this result we clarify under which conditions one may neglect the five-form higher derivative terms. We comment on corrections to the thermodynamics of charged black holes.

Bremsstrahlung and harmonic generation in laser-assisted electron-nucleus collision

“…The laser-assisted scattering of electrons into potentials and the subsequent bremsstrahlung radiation has been treated several times in the last decades [8][9][10][11][12][13][14][15][16] from different points of view and in different ranges of the parameters. In [8][9][10][11] the process is treated in the first Born approximation of the scattering Coulomb potential, the electron-laser interaction is treated by use of the non-relativistic Volkov state [17] and the discussion of the results is always based on asymptotic studies of the formula.…”

Classical theory of laser-assisted spontaneous bremsstrahlung

“…This process has been studied since 1970s [1][2][3][4][5][6]. More recent research [7][8][9][10][11][12][13][14][15] was stimulated by development of intense lasers.…”

Mott scattering in a field of two pulsed laser waves

“…In the presence of an external laser field Mott scattering is accompanied by the stimulated emission and absorption of external field photons. The scattering of an electron by a Coulomb potential of a nucleus in the presence of one and two laser waves has been studied in [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The parametric interference effect was predicted in electron-nucleus scattering in a field of two plane monochromatic waves [25][26][27].…”
