Recently, Miranowicz et al compared three different definitions of antibunching in non-stationary fields and found that they are by no means equivalent. In particular, they may lead to contradictory predictions of the photon antibunching. We consider another violation of the Cauchy-Schwarz inequality in non-classical and non-stationary fields which we term as hyperbunching. Similarly, this leads to three different definitions of hyperbunching in non-stationary fields which, again, are by no means equivalent and may lead to contradictory predictions of this phenomenon. We analyse these different concepts of anti- and hyperbunching in the non-stationary resonance fluorescence from a bichromatically driven two-level atom.
