Generalised Bogoliubov transformation coefficients for para-Bose states
H. E. De Meyer, Guido Vanden Berghe · Journal of Physics A Mathematical and General · 1980
Simple expressions are obtained for the coefficients which connect a para-Bose state containing an arbitrary number of quasiparticles with its transformed state under a real boson and a complex generalised Bogoliubov transformation.
