Holographic sliding stripes
Niko Jokela, Matti Jarvinen, Matthew Lippert
Holographic models provide unique laboratories to investigate non-linear physics of transport in inhomogeneous systems. We provide a detailed account of both DC and AC conductiviti…
Correlation functions in theories with Lifshitz scaling
Ville Keranen, Watse Sybesma, Phillip Szepietowski +1
The 2+1 dimensional quantum Lifshitz model can be generalised to a class of higher dimensional free field theories that exhibit Lifshitz scaling. When the dynamical critical expone…
Breaking the sound barrier in AdS/CFT
Carlos Hoyos, Niko Jokela, David Rodríguez Fernández +1
It has been conjectured that the speed of sound in holographic models with UV fixed points has an upper bound set by the value of the quantity in conformal field theory. If true, t…
New solutions for non-Abelian cosmic strings
Mark Hindmarsh, Kari Rummukainen, David J. Weir
We study the properties of classical vortex solutions in a non-Abelian gauge theory. A system of two adjoint Higgs fields breaks the SU(2) gauge symmetry to , producing 't Hoo…
Canonical formulation and path integral for local vacuum energy sequestering
R. Bufalo, J. Klusoň, M. Oksanen
We establish the Hamiltonian analysis and the canonical path integral for a local formulation of vacuum energy sequestering. In particular, by considering the state of the universe…
Non-relativistic anyons from holography
Niko Jokela, Jarkko Järvelä, Alfonso V. Ramallo
We study generic types of holographic matter residing in Lifshitz invariant defect field theory as modeled by adding probe D-branes in the bulk black hole spacetime characterized b…
