The Spectrum of Topologically Massive Quantum Electrodynamics
We discuss the possibility for the spectrum of topologically massive quantum
electrodynamics with spinor matter fields to contain unexpected and unusual
stable particle excitations for certain values of the topological photon mass.
The new field theoretical phenomena arising from this novel spectral structure
are briefly discussed.Comment: 14 pages, plain TeX; PUPT-1364, UBCTP 92-03
Investigations of Pairing in Anyon Systems
We investigate pairing instabilities in the Fermi-liquid-like state of a
single species of anyons. We describe the anyons as Fermions interacting with a
Chern-Simons gauge field and consider the weak coupling limit where their
statistics approaches that of Fermions. We show that, within the conventional
BCS approach, due to induced repulsive Coulomb and current-current
interactions, the attractive Aharonov-Bohm interaction is not sufficient to
generate a gap in the Fermion spectrum.Comment: (11 pages, 2 Figures not included
Z_N Phases in Hot Gauge Theories
We argue that the \zn phases of hot gauge theories cannot be realized as a
real system with an Hermitean density matrix.Comment: 7 page
