Double sine-Gordon model revisited
G. Takacs, F. Wagner
We reconsider the mass spectrum of double sine-Gordon theory where recent semiclassical results called into question the previously accepted picture. We use the Truncated Conformal…
SUSY sine-Gordon theory as a perturbed conformal field theory and finite size effects
Z. Bajnok, C. Dunning, L. Palla +2
We consider SUSY sine-Gordon theory in the framework of perturbed conformal field theory. Using an argument from Zamolodchikov, we obtain the vacuum structure and the kink adjacenc…
The General Coset Orbifold Action
M. B. Halpern, F. Wagner
Recently an action formulation, called the general WZW orbifold action, was given for each sector of every WZW orbifold. In this paper we gauge this action by general twisted gauge…
Nonperturbative study of the two-frequency sine-Gordon model
Z. Bajnok, L. Palla, G. Takacs +1
The two-frequency sine-Gordon model is examined. The focus is mainly on the case when the ratio of the frequencies is 1/2, given the recent interest in the literature. We discuss t…
Symplectic and orthogonal Lie algebra technology for bosonic and fermionic oscillator models of integrable systems
A. J. Macfarlane, H. Pfeiffer, F. Wagner
To provide tools, especially L-operators, for use in studies of rational Yang-Baxter algebras and quantum integrable models when the Lie algebras so(N) (b_n, d_n) or sp(2n) (c_n) a…
Yang-Baxter Algebra for the n-Harmonic Oscillator Realisation of sp(2n,R)
A. J. Macfarlane, F. Wagner
Using a rational R-matrix associated with the 4 x 4 defining matrix representation of c_2=sp(4), the Lie algebra of Sp(4), a one-site operator solution of the associated Yang-Baxte…
Geometric quantisation of the global Liouville mechanics
Z. Bajnok, D. Nogradi, D. Varga +1
The reduced SL(2,R) WZW quantum mechanics is analysed in the framework of geometric quantization. The spectrum of the Hamiltonian is determined, and it is found, that contrary to t…
