Charge screening effect on hadron-quark mixed phase in compact stars
Abstract
We study the charge screening effect in the hadron-quark mixed phase. By including the charge screening effect, rearrangement of charged particles occurs and some part becomes locally charge-neutral. As a result the equation of state for the mixed phase becomes close to that given by the Maxwell construction, which means that the Maxwell construction would effectively gain the physical meaning again even in the system with two or more chemical potentials. We also discuss the interplay of the surface tension and the Coulomb interaction. Both effects would restrict the region of the mixed phase in the core of hybrid stars.
