Novel features of attractors and transseries in non-conformal Bjorken flows

Understand

In this work we investigate the impact of conformal symmetry breaking on hydrodynamization of a far-from-equilibrium fluid.

• We find a new kind of transseries solutions for the non-conformal hydrodynamic equations of a longitudinal boost invariant expanding plasma.
• The new transseries solutions unveil a rich physical structure which arises due to the interplay of different physical scales.
• In the perfect fluid case the non-conformal speed of sound slows down the cooling of the temperature due to the emergence of logarithmic corrections that depends on the mass of the particle.
