Chun-Mei Pi, Shu-Hua Yang, Xiao-Ping Zheng
TL;DR
This paper investigates the radiative viscosity in superfluid neutron-proton-electron matter, revealing that at lowest order, its ratio to bulk viscosity matches that of normal matter, providing insights into superfluid effects on viscosity.
Contribution
It extends the understanding of radiative viscosity to superfluid matter, showing the ratio to bulk viscosity remains unchanged at lowest order, which was not previously established.
Findings
Radiative viscosity ratio to bulk viscosity is unchanged in superfluid matter at lowest order.
The study provides a theoretical extension of viscosity concepts to superfluid nuclear matter.
Results support the applicability of normal matter viscosity ratios to superfluid conditions.
Abstract
The radiative viscosity of superfluid matter is studied, and it is found that to the lowest order of the ratio of radiative viscosity to bulk viscosity is the same as that of the normal matter.
