On the Deconstruction of Time
Z. Berezhiani, A. Gorsky, I. I. Kogan
In this note we discuss the possibility to get a time rather than space in the scenario of (de)construction of new dimension.
Conformal Orbifold Partition Functions from Topologically Massive Gauge Theory
P. Castelo Ferreira, I. I. Kogan, R. J. Szabo
We continue the development of the topological membrane approach to open and unoriented string theories. We study orbifolds of topologically massive gauge theory defined on the geo…
Hagedorn inflation of D-branes
Steven Abel, Katherine Freese, Ian I. Kogan
We examine the cosmological effects of the Hagedorn phase in models where the observable universe is pictured as a D-brane. It is shown that, even in the absence of a cosmological…
Toroidal Compactification in String Theory from Chern-Simons Theory
P. Castelo Ferreira, Ian I. Kogan, Bayram Tekin
A detailed study of the charge spectrum of three dimensional Abelian Topological Massive Gauge Theory (TMGT) is given. When this theory is defined on a manifold with two disconnect…
String Thermodynamics in D-Brane Backgrounds
S. A. Abel, J. L. F. Barbon, I. I. Kogan +1
We discuss the thermal properties of string gases propagating in various D-brane backgrounds in the weak-coupling limit, and at temperatures close to the Hagedorn temperature. We d…
Induced Dilaton in Topologically Massive Quantum Field Theory
I. I. Kogan, A. Momen, R. J. Szabo
We consider the conformally-invariant coupling of topologically massive gravity to a dynamical massless scalar field theory on a three-manifold with boundary. We show that, in the…
