Attractor for ( 1 + 1 ) D viscous hydrodynamics with general rapidity distribution

Year: 2025

Type: article

Abstract: The attractor, which is supposed to be one of the possible answers for the early applicability of hydrodynamics in the evolution with different initial conditions, has attracted great attention to the fast decreasing of degrees of freedom in heavy ion collisions. We find attractor behaviors for 1 + 1 D viscous hydrodynamics with general rapidity distribution based on Müller-Isreal-Stewart theory. Meanwhile, we also observe that a rapid expansion in the fluid velocity is essential for a rapid early time attractor.
