Non-ideal classical plasma: laser pulse effects and dynamic dipole polarizabilities

Abstract

Abstract The properties of a hydrogen atom inside a non-ideal classical plasma, in terms of its behaviour in the presence of an applied laser pulse, are explored. The strength of the pulse is chosen such that it mantains near sphericity of the system. The pulse parameters have a strong bearing on the final state attained by the system after its interaction with the pulse. Dynamic dipole polarizability is calculated and the poles are observed to be red shifted with increase in non-ideality as well as increase in temperature of plasma. These polarizabilities for frequencies of the field below the frequency corresponding to the first pole are found to be greater for larger values of field frequencies, plasma non-ideality and electron plasma temperatures.
