abstract: |
In this paper we prove an extension of the usual freezing trick argument which can be applied
to a number of quasi-exactly solvable spin models of CalogeroÂSutherland type. In order to
illustrate the application of this method we analyze a partially solvable spin chain presenting
near-neighbors interactions which was introduced and studied in J. Phys. A: Math. Theor. 40
(2007) 1857Â1883; Nucl. Phys. 789 (2008) 452Â482. Our discussion focuses on the existence
of integer eigenvalues. |
