Quasi-Particles, Conformal Field Theory, and -Series
S. Dasmahapatra, R. Kedem, T. R. Klassen +2
We review recent results concerning the representation of conformal field theory characters in terms of fermionic quasi-particle excitations, and describe in detail their construct…
Fermionic Sum Representations for Conformal Field Theory Characters
R. Kedem, T. R. Klassen, B. M. McCoy +1
We present sum representations for all characters of the unitary Virasoro minimal models. They can be viewed as fermionic companions of the Rocha-Caridi sum representations, the la…
Fermionic Quasi-Particle Representations for Characters of
R. Kedem, T. R. Klassen, B. M. McCoy +1
We present fermionic quasi-particle sum representations for some of the characters (or branching functions) of ~ ~for all simply-lace…
Sine-Gordon =/= Massive Thirring, and Related Heresies
Timothy R. Klassen, Ezer Melzer
By viewing the Sine-Gordon and massive Thirring models as perturbed conformal field theories one sees that they are different (the difference being observable, for instance, in fin…
Kinks in Finite Volume
Timothy R. Klassen, Ezer Melzer
A (1+1)-dimensional quantum field theory with a degenerate vacuum (in infinite volume) can contain particles, known as kinks, which interpolate between different vacua and have non…
Rg Flows in the -Series of Minimal Cfts
Timothy R. Klassen, Ezer Melzer
Using results of the thermodynamic Bethe Ansatz approach and conformal perturbation theory we argue that the -perturbation of a unitary minimal -dimensional conform…
