Effect of shear viscosity on antikaon nucleation bubbles in neutron star

In the past few years there has been a growing interest in the study of nucleation process of bubbles of a new phase in first order phase transitions. The goal is to compute the probability that a bubble of a new phase, such as quark matter, kaon condensed phase, appears in a system of initial (hadron) phase near the critical temperature. It was shown that the shear viscosity might control the initial growth rate of a bubble of the quark phase. Recently, calculations of shear viscosity involving antikaon condensation in neutron star matter are carried out. This motivates to investigate the effect of shear viscosity on the nucleation process of bubbles of K- condensed phase in neutron stars, which has not been investigated so far
