Holographic models with anisotropic scaling

Holographic Superconductors with Lifshitz Scaling

Black holes in asymptotically Lifshitz spacetime provide a window onto finite temperature effects in strongly coupled Lifshitz models. We add a Maxwell gauge field and charged matter to a recently proposed gravity dual of 2+1 dimensional Lifshitz theory. This gives rise to charged black holes with scalar hair, which correspond to the superconducting phase of holographic superconductors with z >...

On anisotropic and inhomogeneous doped holographic matter

Anisotropic scaling of magnetohydrodynamic turbulence.

We present a quantitative estimate of the anisotropic power and scaling of magnetic field fluctuations in inertial range magnetohydrodynamic turbulence, using a novel wavelet technique applied to spacecraft measurements in the solar wind. We show for the first time that, when the local magnetic field direction is parallel to the flow, the spacecraft-frame spectrum has a spectral index near 2. T...

Entanglement tsunami: universal scaling in holographic thermalization.

We consider the time evolution of entanglement entropy after a global quench in a strongly coupled holographic system, whose subsequent equilibration is described in the gravity dual by the gravitational collapse of a thin shell of matter resulting in a black hole. In the limit of large regions of entanglement, the evolution of entanglement entropy is controlled by the geometry around and insid...

Scaling and scaling crossover for transport on anisotropic fractal structures

Diffusion into fibrous anisotropic structures can exhibit a variety of crossover phenomena. Scaling of amount adsorbed versus time in such structures is studied by standard renormalization methods as a function of anisotropy for several kinds of discrete models. Total mass adsorbed as a function of time from a reservoir attached at a single point exhibits different power laws in different logar...
