Quantum-mechanical dielectric model of the electron–ion collision frequency in strong laser fields

摘要: The electron–ion collision frequency in a strong laser field is calculated the framework of quantum Vlasov theory first-order Born approximation. Using Wigner representation density matrix, can be expressed terms Lindhard dielectric function and close correspondence between classical quantum-mechanical approaches obtained. Asymptotic formulas for high-frequency weak electric fields are obtained compared with complete numerical calculations. basic strong-field behavior explained cold plasma model.
