Abstract

The states , defined as up to a normalization constant and is a nonnegative integer, are shown to be the eigenstates of where is a nonlinear function of the number operator . The explicit form of is constructed. The eigenstates of this operator for negative values of are introduced. The properties of these states are discussed and compared with those of the state .
