  The mechanical action on matter of the electromagnetic field emitted by a
fluctuating source is governed by its statistics. In particular, thermal
sources and vacuum fluctuations exert on bodies those well-known Casimir (C)
and Van der Waals (VdW) forces. However, we have recently demonstrated that
partially coherent random electromagnetic fields emitted by tailored optical
sources, induce a photonic force on particles which, in particular, may be
equivalent to those of Van der Waals and Casimir.
