Energy Flux Density And Thermal Conductivity Of Lorentz Plasma With The Power-law Distribution And In Strong Magnetic Field

The transport phenomena of plasma systems have been widely studied and used in the traditional Boltzmann statistics.With the development of physics,we have found that traditional statistics for describing the systems with long-range interactions have limitations,and in order to describe the systems better,one have developed a new theory called nonextensive statistical theory that is suitable for the systems with Coulomb long-range interactions and Newtonian gravitation.The research of new properties about plasma with power-law distribution under the nonextensive statistics has become a hot and frontier theoretical topic of international plasma physical research for a time.On the base of nonextensive statistical theory,we have studied the transport properties of Lorentz plasma with power-law distribution,and we also discuss the energy flux density and thermal conductivity of Lorentz plasma with strong magnetic field through the transport equation and power-law q-distribution.During the process of research,we consider the plasma that is fully ionized and assume there are two kinds of particles: electrons and ions.The electrons and ions in the plasma obey the power-law distribution and are with q-parameters different from each other.After a series of derivation and operation,the new expressions about energy flux and thermal conductivity of Lorentz plasma can be accurately derived to follow power-law distribution in strong magnetic field.The result show that the new expressions are dependent on the nonextensive parameter q,and when we take q?1,they can be reduced to the standard forms with Boltzmann statistics.
