How Gubser flow ends in a holographic conformal theoryBanerjee, Avik (Avtor) Mitra, Toshali (Avtor) Mukhopadhyay, Ayan (Avtor) Soloviev, Alexander (Avtor) relativistic hydrodynamicsGubser flowGubser flow is an axis-symmetric and boost-invariant evolution in a relativistic quantum field theory which is best studied by mapping $\bf{R}$$^{3,1}$ to $dS_3 \times \bf{R}$ when the field theory has conformal symmetry. We show that at late de-Sitter time, which corresponds to large proper time and central region of the future wedge within $\bf{R}$$^{3,1}$, the holographic conformal field theory plasma can reach a state in which $\epsilon = P_T = - P_L$, with $\epsilon$, $P_T$ and $P_L$ being the energy density, transverse and longitudinal pressures, respectively. We further determine the full sub-leading behaviour of the energy–momentum tensor at late time. Restricting to flows in which the energy density decays at large transverse distance from the central axis in $\bf{R}$$^{3,1}$, we show that this decay should be faster than any power law. Furthermore, in this case the energy density also vanishes in $\bf{R}$$^{3,1}$ faster than any power as we go back to early proper time. Hydrodynamic behavior can appear in intermediate time.20242024-11-25 14:25:38Članek v reviji165161sl
