Temporal cavity solitons (CSs) are pulses of light that can persist endlesslyin dispersive, nonlinear optical resonators. They have been extensively studiedin the context of resonators with purely cubic (Kerr-type) nonlinearity thatare externally-driven with a monochromatic continuous wave laser -- in suchsystems, the solitons manifest themselves as unique attractors whose carrierfrequency coincides with that of the external driving field. Recent experimentshave, however, shown that a qualitatively different type of temporal CS canarise via parametric down-conversion in resonators with simultaneous quadraticand cubic nonlinearity. In contrast to conventional CSs in pure-Kerrresonators, these \emph{parametrically-driven cavity solitons} come in twodifferent flavours with opposite phases, and they are spectrally centred athalf of the frequency of the driving field. Here, we theoretically andnumerically show that, under conditions of bichromatic driving, suchparametrically-driven CSs can also arise in dispersive resonators with pureKerr nonlinearity. In this case, the solitons arise through parametricfour-wave mixing, come with two distinct phases, and have a carrier frequencyin between the two external driving fields. We show that, when all waves areresonant, the solitons can experience long-range interactions due to theirback-action on the intracavity fields at the pump frequencies, and we discussthe parameter requirements for the solitons' existence. Besides underlining thepossibility of exciting a new type of cavity soliton in dispersive Kerrcavities, our work advances the theoretical modeling of resonators that arecoherently-driven with polychromatic fields.
