- W2091005989 abstract "The non-compact analogue O(2,1) of the rotation group in three dimensions is generated by three scalar operations that create two phonons, annihilate two phonons, and count them. These generators commute with those of the symmetry groups for the octahedral systems E(X) epsilon , Gamma 8(X) tau 2, and, under conditions of equal frequencies and equal couplings, Gamma 8(X)( epsilon (+) tau 2). This permits an independent method for finding the matrix elements of the interaction term of the Jahn-Teller Hamiltonian to be devised. The parallel construction of the basis states for these three Jahn-Teller systems makes it transparent why the energy matrices should be the same (apart from trivial differences). The symmetries found by O'Brien (1977), for some isoscalar factors O(5) are related to the substitution P to -P-1, where P, the quasispin, defines representations of O(2,1). Analogues of O'Brien's symmetries exist in O(3) and in the groups used in atomic shell theory." @default.
