    "abstract": "We present a generalized equations-of-motion method that efficiently\ncalculates energy spectra and matrix elements for algebraic models. The method\nis applied to a 5-dimensional quartic oscillator that exhibits a quantum phase\ntransition between vibrational and rotational phases. For certain parameters,\n10 by 10 matrices give better results than obtained by diagonalising 1000 by\n1000 matrices.",
