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…
