Transverse oscillation in relativistic electron-positron plasma with q-distribution
摘要
Abstract
The dispersion relation of transverse oscillation in the unmagnetized, collisionless, isotropic and relativistic electron-positron plasma is discussed in the context of q-distribution. The dispersion equations in connection with q-parameter are derived and then the analytical dispersion laws for ultra-relativistic electron-positron plasma are obtained under the long-wavelength approximation and the short-wavelength condition. The dispersion equations are numerically simulated with the purpose of getting the full dispersion curve, and the numerical solutions are coincident with the analytical results in the cases of long-wavelength and short-wavelength for ultra-relativistic electron-positron plasma. It is shown that the dispersion relation in the context of q-distri-bution is related to q-parameter and temperature, and in the limiting case ( q→ 1), the classical dispersion relation based on the Maxwellian distribution is recovered.关键词
