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 U(1) at high temperature.

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...
Electromagnetic form factors of electrodisintegration of light nuclei near threshold Yalcin, C; Rekalo, MP; Koru, H (1998-06-01) The general structure of electromagnetic currents for electrodisintegration of nuclei near threshold, e(-) + A --> e(-) + A(1) + A(2) (A, A(1) and A(2) are arbitrary nuclei or hadrons with spins 0, 1/2 and 1), are established. Considering nuclei as elementary particles with the definite values of spin and space parity and using the conservation of hadronic electromagnetic current and P-invariance of hadron electromagnetic interaction, the spin structure of the amplitudes of the processes gamma* + A --> A(1)...
Thermal decomposition of glycidyl azide polymer by direct insertion probe mass spectrometry Fazlioǧlu, Hatice; Hacaloğlu, Jale (2002-01-01) Thermal decomposition reactions and products of glycidyl azide polymer (GAP), have been investigated by direct insertion mass spectrometry and evolved gas analyses by FTIR spectroscopy techniques. It has been observed that thermal degradation of GAP begins with cleavage of the side groups. Although the main decomposition started with the elimination of molecular nitrogen from the azide functional group, degradation initiated by loss of N-3 and CH2N3, depolymerization type reactions were also identified. Rea...
Reaction kinetics of calcium chloride - ammonia reactive system and theoretical simulation of heat and mass transfer in porous slab pellets Karakaş Helvacı, Zeynep; Uludağ, Yusuf; Karakaş, Gürkan; Department of Chemical Engineering (2023-1-24) The reactive systems between ammoniated CaCl2 and NH3 were investigated in terms of heat and mass transport phenomena coupled with reaction kinetics. The reversible reaction rate based on the Langmuir-Hinshelwood model was suggested to express the net reaction rate, including both the adsorption and desorption terms. Experiments at three temperatures were conducted to evaluate the kinetic parameters, pre-exponential factors, and activation energies. The parameters were evaluated by Non-Linear Regression (NL...
Vortex lattices in dipolar two-component Bose-Einstein condensates Ghazanfari, N.; Keleş, Ahmet; Oktel, M. O. (2014-02-01) We consider a rapidly rotating two-component Bose-Einstein condensate with short-range s-wave interactions as well as dipolar coupling. We calculate the phase diagram of vortex lattice structures as a function of the intercomponent s-wave interaction and the strength of the dipolar interaction. We find that the long-range interactions cause new vortex lattice structures to be stable and lead to a richer phase diagram. Our results reduce to the previously found lattice structures for short-range interactions...
