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…
Conformal quantum mechanics and holographic quench
Jarkko Järvelä, Ville Keränen, Esko Keski-Vakkuri
Recently, there has been much interest in holographic computations of two-point non-equilibrium Green functions from AdS-Vaidya backgrounds. In the strongly coupled quantum field t…
Non-equilibrium scalar two point functions in AdS/CFT
Ville Keranen, Philipp Kleinert
In the first part of the paper, we discuss different versions of the AdS/CFT dictionary out of equilibrium. We show that the Skenderis - van Rees prescription and the "extrapolate"…
Holographic thermalization with Lifshitz scaling and hyperscaling violation
Piermarco Fonda, Lasse Franti, Ville Keranen +3
A Vaidya type geometry describing gravitation collapse in asymptotically Lifshitz spacetime with hyperscaling violation provides a simple holographic model for thermalization near…
Thermalization of the spectral function in strongly coupled two dimensional conformal field theories
V. Balasubramanian, A. Bernamonti, B. Craps +5
Using Wigner transforms of Green functions, we discuss non-equilibrium generalizations of spectral functions and occupation numbers. We develop methods for computing time-dependent…
Thermal Correlators in Holographic Models with Lifshitz scaling
Ville Keranen, Larus Thorlacius
We study finite temperature effects in two distinct holographic models that exhibit Lifshitz scaling, looking to identify model independent features in the dual strong coupling phy…
Solitons as Probes of the Structure of Holographic Superfluids
Ville Keränen, Esko Keski-Vakkuri, Sean Nowling +1
Detailed features of solitons in holographic superfluids are discussed. Using solitons as probes, we study the behavior of holographic superfluids by varying the scaling dimension…
Inhomogeneous Structures in Holographic Superfluids: I. Dark Solitons
Ville Keranen, Esko Keski-Vakkuri, Sean Nowling +1
We begin an investigation of inhomogeneous structures in holographic superfluids. As a first example, we study domain wall like defects in the 3+1 dimensional Einstein-Maxwell-Higg…
Dark Solitons in Holographic Superfluids
Ville Keranen, Esko Keski-Vakkuri, Sean Nowling +1
We construct dark soliton solutions in a holographic model of a relativistic superfluid. We study the length scales associated with the condensate and the charge density depletion,…
