We study the parameter space of D-dimensional cosmological Einstein gravity together with quadratic curvature terms. In D < 4 there are in general two distinct (anti)-de Sitter vacua. We show that, for an appropriate choice of the parameters, there exists a critical point for one of the vacua, with only massless tensor, but neither massive tensor nor scalar, gravitons. At criticality, the linearized excitations have formally vanishing energy (as do black hole solutions). A further restriction of the parameters gives a one-parameter cosmological Einstein plus Weyl(2) model with a unique vacuum, whose Lambda is determined.

Phase transition in compact QED3 and the Josephson junction Onemli, VK; Tas, M; Tekin, Bayram (2001-08-01) We study the finite temperature phase transition in 2+1 dimensional compact QED and its dual theory: Josephson junction. Duality of these theories at zero temperature was established long time ago in [1]. Phase transition in compact QED is well studied thus we employ the 'duality' to study the superconductivity phase transition in a Josephson junction. For a thick junction we obtain a critical temperature in terms of the geometrical properties of the junction.
Non-Abelian gauge theories of the Yang-Mills type Abuhatab, Ahmed; Başkal, Sibel; Department of Physics (2003) In this thesis, starting from the effective Lagrangians of the standard Yang-Mills, higher derivative Yang-Mills and the Chern-Simons- Yang-Mills theories, we have given the corresponding field equations and the symmetric gauge invariant energy- momentum tensors. Lagrangians containing higher derivative terms have been found useful for discussing the long lange effects of the gluon fields. A numeri cal solution is found for a spherically symmetric static gauge potential. On the other hand, Chern-Simons- Yan...
Scalar waves in spacetimes with closed timelike curves Buğdaycı, Necmi; Başkal, Sibel; Department of Physics (2005) The existence and -if exists- the nature of the solutions of the scalar wave equation in spacetimes with closed timelike curves are investigated. The general properties of the solutions on some class of spacetimes are obtained. Global monochromatic solutions of the scalar wave equation are obtained in flat wormholes of dimensions 2+1 and 3+1. The solutions are in the form of infinite series involving cylindirical and spherical wave functions and they are elucidated by the multiple scattering method. Explici...
D*Dpi coupling constant in 2+1 flavor lattice QCD Can, Kadir Utku; Özpineci, Altuğ; Erkol, Güray; Department of Physics (2012) Developments in high-performance computing instruments and advancements in the numerical algorithms combined with lattice gauge theory make it possible to simulate Quantum Chromodynamics (QCD), the theory of strongly-interacting quarks and gluons, numerically at nearly physical light-quark masses. In this work we present our results for the $D^*D\pi$ coupling constant as simulated on $32^3 \times 64$, unquenched $2+1$-flavor lattices. We estimate the coupling at the chiral limit as $g_{D^*D\pi} = 16.23 \pm ...
Note on cosmological Levi-Civita spacetimes in higher dimensions Sarıoğlu, Bahtiyar Özgür; Tekin, Bayram (American Physical Society (APS), 2009-04-01) We find a class of solutions to cosmological Einstein equations that generalizes the four dimensional cylindrically symmetric spacetimes to higher dimensions. The AdS soliton is a special member of this class with a unique singularity structure.
