K. Hikami et Y. Komori, DIAGONALIZATION OF THE ELLIPTIC RUIJSENAARS MODEL - CORRESPONDENCE WITH THE BELAVIN MODEL, The European Physical Journal. B: Condensed Matter Physics, 5(3), 1998, pp. 583-588
Studied is the elliptic Ruijsenaars model, which is a difference analo
gue of the Calogero-Sutherland-Moser model. Using a novel relationship
between the elliptic Ruijsenaars operator and the transfer matrix of
the Belavin model, we diagonalize the Ruijsenaars operator by the alge
braic Bethe ansatz method.
