Phase transition in compact QED3 and the Josephson junction

Onemli, VK

Tekin, Bayram
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.


Deconfinement at N > 2: SU(N) Georgi-Glashow model in 2+1 dimensions
Kogan, II; Tekin, Bayram; Kovner, A (2001-05-01)
We analyse the deconfining phase transition in the SU(N) Georgi-Glashow model in 2 + 1 dimensions. We show that the phase transition is second order for any N, and the universality class is different from the Z(N) invariant Villain model. At large N the conformal theory describing the fixed point is a deformed SU(N)(1) WZNW model which has N - 1 massless fields. It is therefore likely that its self-dual infrared fixed point is described by the Fateev-Zamolodchikov theory of Z(N) parafermions.
Deconfining phase transition in 2+1 D: the Georgi-Glashow model
Dunne, G; Kogan, II; Kovner, A; Tekin, Bayram (2001-01-01)
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 magnetic Z(2) symmetry and that it is in the Ising universality class. We find that neglecting effects of the charged W bosons leads to incorrect predictions for the value of the critical temperature and the universality class of the transition, as well as for various correlation functions in the high temperature phase. We derive t...
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...
Conformal black hole solutions of axidilaton gravity in D dimensions
Cebeci, H; Dereli, T (2002-02-15)
Static, spherically symmetric solutions of axidilaton gravity in D dimensions are given in the Brans-Dicke frame for arbitrary values of the Brans-Dicke constant omega and an axion-dilaton coupling parameter k. The mass and the dilaton and axion charges are determined and a BPS bound is derived. There exists a one-parameter family of black hole solutions in the scale-invariant limit.
Electrically charged vortex solutions in Born-Infeld theory with a Chern-Simons term
Çimşit, Mustafa; İpekoğlu, Yusuf; Department of Physics (2003)
In this thesis, we considered electrically charged vortex solutions of Born- Infeld Chern-Simons gauge theory in 2+1 dimensions, with a sixth order charged scalar eld potential. For this purpose, rst Nielsen-Olesen vortex solutions are extensively reviewed. Then, Born-Infeld and Chern-Simons theories are summarized. Finally, vortex solutions are obtained for the Born-Infeld-Higgs system with a Chern-Simons term. These solutions are analyzed numerically, comparing their properties with Nielsen-Olesen vortices.
