Magnetic Response in the Holographic Insulator/Superconductor Transition
Marc Montull, Oriol Pujolàs, Alberto Salvio +1
We study the magnetic response of holographic superconductors exhibiting an insulating "normal" phase. These materials can be realized as a CFT compactified on a circle, which is d…
On Asymptotic Darkness in Hořava-Lifshitz Gravity
Emilio Elizalde, Pedro J. Silva
Hořava-Lifshitz gravity is shown to exhibit a peculiar behavior, when scattering amplitudes are considered. At low energies it seems to classicalize i.e. the effective size of the…
Flux Periodicities and Quantum Hair on Holographic Superconductors
Marc Montull, Oriol Pujolas, Alberto Salvio +1
Superconductors in a cylindrical geometry respond periodically to a cylinder-threading magnetic flux, with the period changing from hc/2e to hc/e depending on whether the Aharonov-…
Matter couplings in Horava-Lifshitz and their cosmological applications
Sante Carloni, Emilio Elizalde, Pedro J. Silva
In this paper, the issue how to introduce matter in Hořava-Lifshitz theories of gravity is addressed. This is a key point in order to complete the proper definition of these theori…
Emergent Gauge Fields in Holographic Superconductors
Oriol Domènech, Marc Montull, Alex Pomarol +2
Holographic superconductors have been studied so far in the absence of dynamical electromagnetic fields, namely in the limit in which they coincide with holographic superfluids. It…
An analysis of the phase space of Horava-Lifshitz cosmologies
Sante Carloni, Emilio Elizalde, Pedro J. Silva
Using the dynamical system approach, properties of cosmological models based on the Horava-Lifshitz gravity are systematically studied. In particular, the cosmological phase space…
