I've always stated that the study of condensed matter physics is often as fundamental as any other other areas of physics, despite the connotation that condensed matter physics is "applied" physics and thus, not fundamental. One only needs to look at where Peter Higgs got the inspiration for the Higgs mechanism to falsify that erroneous view of condensed matter.
Well then, add this as another evidence. This article, presented as a talk (presumably by Subir Sachdev), makes a clear connection between condensed matter system and various fundamental physics in other areas of physics, including black holes physics!
Abstract: Many condensed matter experiments explore the finite temperature dynamics of systems near quantum critical points. Often, there are no well-defined quasiparticle excitations, and so quantum kinetic equations do not describe the transport properties completely. The theory shows that the transport co-efficients are not proportional to a mean free scattering time (as is the case in the Boltzmann theory of quasiparticles), but are completely determined by the absolute temperature and by equilibrium thermodynamic observables. Recently, explicit solutions of this quantum critical dynamics have become possible via the AdS/CFT duality discovered in string theory. This shows that the quantum critical theory provides a holographic description of the quantum theory of black holes in a negatively curved anti-de Sitter space, and relates its transport co-efficients to properties of the Hawking radiation from the black hole. We review how insights from this connection have led to new results for experimental systems: (i) the vicinity of the superfluid-insulator transition in the presence of an applied magnetic field, and its possible application to measurements of the Nernst effect in the cuprates, (ii) the magnetohydrodynamics of the plasma of Dirac electrons in graphene and the prediction of a hydrodynamic cyclotron resonance.
What this means is that many of the same physics in these astrophysical/String theory systems can actually, in fact, be studied via condensed matter systems. Fancy that!
