supersymmetric Yang-Mills thermodynamics to order
Margaret E. Carrington, Gabor Kunstatter, Ubaid Tantary
We calculate the resummed perturbative free energy of supersymmetric Yang-Mills in four spacetime dimensions (SYM) to order in the 't Hooft coupling…
Evidence for universal flow and characteristics of early time thermalization in a scalar field model for heavy ion collisions
Margaret E. Carrington, Wade N. Cowie, Gabor Kunstatter +1
We study numerically the evolution of an expanding strongly self-coupled real scalar field. We use a conformally invariant action that gives a traceless energy-momentum tensor and…
Isotropization of a rotating and longitudinally expanding scalar system
Margaret E. Carrington, Gabor Kunstatter, Christopher Phillips +1
We present numerical simulations for the evolution of an expanding system of massless scalar fields with quartic coupling. By setting a rotating, non-isotropic initial configuratio…
A Non-Equilibrium Approach To Holographic Superconductors Using Gradient Flow
Paul Mikula, Margaret E. Carrington, Gabor Kunstatter
We study a charged scalar field in a bulk 3+1 dimensional anti-deSitter spacetime with a planar black hole background metric. Through the AdS/CFT correspondence this is equivalent…
Smooth and sharp creation of a pointlike source for a -dimensional quantum field
L. J. Zhou, Margaret E. Carrington, Gabor Kunstatter +1
We analyse the smooth and sharp creation of a pointlike source for a quantised massless scalar field in -dimensional Minkowski spacetime, as a model for the breakdown of cor…
Black Hole Formation in AdS Einstein-Gauss-Bonnet Gravity
Nils Deppe, Allison Kolly, Andrew R. Frey +1
AdS spacetime has been shown numerically to be unstable against a large class of arbitrarily small perturbations. In arXiv:1410.1869, the authors presented a preliminary study of t…
Stability of AdS in Einstein Gauss Bonnet Gravity
Nils Deppe, Allison Kolly, Andrew Frey +1
Recently it has been argued that in Einstein gravity Anti-de Sitter spacetime is unstable against the formation of black holes for a large class of arbitrarily small perturbations.…
The Generalized Ricci Flow for 3D Manifolds with One Killing Vector
J. Gegenberg G. Kunstatter
We consider 3D flow equations inspired by the renormalization group (RG) equations of string theory with a three dimensional target space. By modifying the flow equations to includ…
Ricci Flow of 3-D Manifolds with One Killing Vector
J. Gegenberg, G. Kunstatter
We implement a suggestion by Bakas and consider the Ricci flow of 3-d manifolds with one Killing vector by dimensional reduction to the corresponding flow of a 2-d manifold plus sc…
Using 3D Stringy Gravity to Understand the Thurston Conjecture
J. Gegenberg, G. Kunstatter
We present a string inspired 3D Euclidean field theory as the starting point for a modified Ricci flow analysis of the Thurston conjecture. In addition to the metric, the theory co…
Varying Fine Structure Constant and Black Hole Physics
Saurya Das, Gabor Kunstatter
Recent astrophysical observations suggest that the value of fine structure constant may be slowly increasing with time. This may be due to an increase of or a d…
Discrete Spectra of Charged Black Holes
Andrei Barvinsky, Saurya Das, Gabor Kunstatter
Bekenstein proposed that the spectrum of horizon area of quantized black holes must be discrete and uniformly spaced. We examine this proposal in the context of spherically symmetr…
Quantum Mechanics of Charged Black Holes
Andrei Barvinsky, Saurya Das, Gabor Kunstatter
We quantize the spherically symmetric sector of generic charged black holes. Thermal properties are encorporated by imposing periodicity in Euclidean time, with period equal to the…
Boundary Dynamics of Higher Dimensional Chern-Simons Gravity
J. Gegenberg, G. Kunstatter
We review the relevance to the black hole entropy problem of boundary dynamics in Chern-Simons gravity. We then describe a recent derivation of the action induced on the four dimen…

We consider the one-loop corrected geometry and thermodynamics of a rotating BTZ black hole by way of a dimensionally reduced dilaton model. The analysis begins with a comprehensiv…

V. Frolov, D. Fursaev, J. Gegenberg +1
In this paper we describe a Liouville gravity which is induced by a set of quantum fields (constituents) and represents a two-dimensional analog of Sakharov's induced gravity. The…
