Query: Classical signal viewpoint to bunching and anti-bunching   The similarity between classical wave mechanics and quantum mechanics (QM)
played an important role in the development of QM (starting with works of De
Broglie, Schr\"odinger, "late Einstein", Lamb, Lande, Mandel, Marshall, Santos,
Boyer, and many others). We present a new wave-type approach, so called
prequantum classical statistical field theory (PCSFT). PCSFT explores an
analogy between some quantum phenomena and classical theory of random fields.
Quantum systems are interpreted as symbolic representations of such fields (not
only for photons, cf. Lande and Lamb, but even for massive particles). All
quantum averages and correlations (including composite systems in entangled
states) can be represented as averages and correlations for classical random
fields. In this paper PCSFT is used to provide a classical signal
representation of bunching and anti-bunching. At least the latter is typically
considered as essentially quantum (nonclassical) phenomenon.
