2+1 d Georgi Glashow Model Near Critical Temperature
Candost Akkaya, Ibrahim Burak Ilhan, Alex Kovner
We study correlations functions of magnetic vortices and Polyakov loop operators in the 2+1 dimensional Georgi-Glashow model in the vicinity of the deconfining phase transi…
Photons without vector fields
Ibrahim Burak Ilhan, Alex Kovner
In this note we continue to pursue the question whether gauge theories can be represented in terms of effective "scalar" degrees of freedom. We provide such a consistent representa…
Conformal Gravity Redux: Ghost-turned-Tachyon
Ibrahim B. Ilhan, Alex Kovner
We analyze conformal gravity in translationally invariant approximation, where the metric is taken to depend on time but not on spatial coordinates. We find that the field mode whi…
The Curious Case of an Effective Theory
Ibrahim Burak Ilhan, Alex Kovner
We describe an effective theory of a scalar field, motivated by some features expected in the low energy theory of gluodynamics in 3+1 dimensions. The theory describes two propagat…
Some Comments on Ghosts and Unitarity: The Pais-Uhlenbeck Oscillator Revisited
Ibrahim Burak Ilhan, Alex Kovner
We give a simple discussion of ghosts, unitarity violation, negative norm states and quantum vs classical behavior in the simplest model with four derivative action - the Pais-Uhle…
