Journal of Physics A Mathematical and GeneralAntinormally ordering some multimode exponential operators by virtue of the IWOP techniqueFan Hong‐YiPublished Feb 21, 1992• 34 citationsPublisherAbstractThe author shows that the technique of integration within ordered product (IWOP) can also provide one with a simple approach to antinormally ordering some multimode exponential operators both in boson and fermion cases.DOI10.1088/0305-4470/25/4/035
