We uplift this action into a 3+1 dimensional $T\bar T$-like deformation of the Skyrme action.

Wiedemann-Franz laws and $Sl(2,\mathbb{Z})$ duality in AdS/CMT holographic duals and one-dimensional effective actions for them

no code implementations • 25 Nov 2020 • Dmitry Melnikov, Horatiu Nastase

In this paper we study the Wiedemann-Franz laws for transport in 2+1 dimensions, and the action of $Sl(2,\mathbb{Z})$ on this transport, for theories with an AdS/CMT dual.

Reheating in holographic cosmology and connecting to $Λ$-MSSM constructions for particle physics

no code implementations • 14 Aug 2020 • Horatiu Nastase

In this paper we model the transition from the non-geometric holographic cosmology regime, to the usual radiation dominated (RD) cosmology, known as reheating in the case of (perturbative) inflation.
