Calorons in Weyl Gauge
Gerald V. Dunne, Bayram Tekin
We demonstrate by explicit construction that while the untwisted Harrington-Shepard caloron is manifestly periodic in Euclidean time, with period , when transf…
Deconfining Phase Transition in 2+1 D: the Georgi-Glashow Model
Gerald Dunne, Ian I. Kogan, Alex Kovner +1
We analyze the finite temperature deconfining phase transition in 2+1 dimensional Georgi-Glashow model. We show explicitly that the transition is due to the restoration of the magn…
Magnetic Symmetries and Vortices In Chern-Simons Theories
Gerald Dunne, Alex Kovner, Bayram Tekin
We study the locality properties of the vortex operators in compact U(1) Maxwell-Chern-Simons and SU(N) Yang-Mills-Chern-Simons theories in 2+1 dimensions. We find that these theor…
Multi-instantons in R^4 and Minimal Surfaces in R^{2,1}
Bayram Tekin
It is known that self-duality equations for multi-instantons on a line in four dimensions are equivalent to minimal surface equations in three dimensional Minkowski space. We exten…
Holographic renormalization group flow, Wilson loops and field-theory beta-functions
Ian I. Kogan, Martin Schvellinger, Bayram Tekin
We study the Renormalization Group (RG) flow of critical bosonic background fields in the framework of the RG approach to string theory. In this approach quantum field theory beta-…
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…
Gravitating Instantons In 3 Dimensions
Andrew Ferstl, Bayram Tekin, Victor Weir
We study the Einstein-Chern-Simons gravity coupled to Yang-Mills-Higgs theory in three dimensional Euclidean space with cosmological constant. The classical equations reduce to Bog…
