On the hydrodynamic description of holographic viscoelastic models

On the hydrodynamic description of holographic viscoelastic models

We show that the correct dual hydrodynamic description of homogeneous holographic models with spontaneously broken translations must include the so-called “strain pressure” – a novel transport coefficient proposed recently. Taking this new ingredient into account, we investigate the near-equilibrium...
