Investigation of quantum effects on the electron nanobunching gain for attosecond pulse generation

Abstract

In this paper, the influence of role of quantum effects such as spin and tunneling on attosecond pulse generation in turbulent dense plasma is investigated. Calculations show that increasing the density gradient by a factor of 10, in the case of short-wavelengths, leads to about 90%, and in the case of long-wavelengths, leads to a 66% decrease in the nanobunching gain. Increasing the quantum parameter by a factor of 10 in the short-wavelength range will result in about 80% and in the long-wavelength range will lead to a 25% reduction in the nanobunching gain saturation time generated by the Weibel instability. Increasing the quantum parameter will increase the saturation value of the density perturbation.
