Transport properties of a charged drop in an external electric field

Abstract

Transport properties of a charged droplet of weakly interacting particles in an external field are investigated. A non-equilibrium distribution function which describes a process of the droplet transverse evolution with constant entropy in an external electric field is calculated. With the help of this distribution function, shear viscosity coefficients in the transverse plane are calculated as well. They are found to be very small and depend on the time of the droplet's expansion in a hydrodynamical regime and external field value. An applicability of the results to the description of initial states of quark-gluon plasma obtained in high-energy interactions of nuclei is also discussed.
