Deconfining phase transition in 2+1 D: the Georgi-Glashow model

Dunne, G

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 the effective action for the Polyakov loop in the high temperature phase and calculate the correlation functions of magnetic vortex operators.


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.
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.
Instanton molecules at high temperature - the Georgi-Glashow model and beyond
Kogan, II; Tekin, Bayram; Kovner, A (2001-03-01)
We show that correlators of some local operators in gauge theories are sensitive to the presence of the instantons even at high temperature where the latter are bound into instanton-anti-instanton "molecules". We calculate correlation functions of such operators in the deconfined phase of the 2+1 dimensional Georgi-Glashow model and discuss analogous quantities in the chirally symmetric phase of QCD. We clarify the mechanism by which the instanton-anti-instanton molecules contribute to the anomaly of axial ...
Temperature dependence of the polarization, dielectric constant, damping constant and the relaxation time close to the ferroelectric-paraelectric phase transition in LiNbO3
Kiraci, A.; Yurtseven, Hasan Hamit (2017-01-01)
We calculate the order parameter (spontaneous polarization) and the inverse dielectric susceptibility at various temperatures in the ferroelectric phase of LiNbO3 for its ferroelectric-paraelectric phase transition (T-C =1260 K) using the Landau phenomenological model. For this calculation, the Raman frequencies of the soft optic mode (TO1) are used as the order parameter and the fitting procedure is employed for both the order parameter and the inverse dielectric susceptibility by means of the observed dat...
Total outage capacity of randomly-spread coded-CDMA with linear multiuser receivers over multipath fading channels
Ertug, O; Sayrac, B; Baykal, Buyurman; Yucel, MD (2003-07-03)
We address in this paper the derivation and analysis of the outage spectral efficiencies achievable with linear multiuser receivers over randomly-spread multipath fading time-varying coded-CDMA channels. The basis of the derivations is the use of non-asymptotic average eigenvalue densities of random cross-correlation matrices. The analysis give important clues on the achievable capacity with linear multiuser receivers under non-ergodic transmission situations.
