Abstract
This paper presents the results of a study of the optical properties of hydrogen, specifically the reflection and refraction coefficients of electromagnetic waves, with the permittivity of the substance described by the generalized Drude–Lorentz model. This paper examines the longitudinal and transverse spectra of microscopic ion current oscillations in hydrogen at various temperatures and densities, and analyzes the influence of electron exchange and correlation effects. The study was conducted using the effective interaction potential, taking into account a local field correction obtained from quantum Monte Carlo simulations. The use of accurate local field models, such as approximations based on quantum statistical calculations, allows for the reliable reproduction of the transport and optical properties of dense electron systems. In particular, taking into account the local field function leads to significant corrections in the calculations of optical and dynamic properties, which is critical for modeling hot dense matter, metallized plasma, and degenerate electron systems. In addition, the presence of an exact form of the local field function allows us to correctly describe the optical and dynamic properties of the plasma, including the reflection and absorption coefficients and natural oscillation modes.
