Correlators of the Kazakov-Migdal Model
M. I. Dobroliubov, Yu. Makeenko, G. W. Semenoff
We derive loop equations for the one-link correlators of gauge and scalar fields in the Kazakov-Migdal model. These equations determine the solution of the model in the large N lim…
The Superfluidity and Experimental Properties of Odd-Energy-Gap Superconductors
M. Dobroliubov, E. Langmann, P. C. E. Stamp
We consider the experimental properties of superconductors with a gap which is an odd function of energy $\bepsk=\epsk - μ$, i.e.\ , a gap which vanishes everywhere on the Fermi su…
The Spectrum of Topologically Massive Quantum Electrodynamics
Mikhail I. Dobroliubov, David Eliezer, Ian I. Kogan +2
We discuss the possibility for the spectrum of topologically massive quantum electrodynamics with spinor matter fields to contain unexpected and unusual stable particle excitations…
Z_N Phases in Hot Gauge Theories
Wei Chen, Mikhail Dobroliubov, Gordon Semenoff
We argue that the \zn phases of hot gauge theories cannot be realized as a real system with an Hermitean density matrix.
