  The physics reach of a low threshold (100 eV) scintillating argon bubble
chamber sensitive to Coherent Elastic neutrino-Nucleus Scattering (CE$\nu$NS)
from reactor neutrinos is studied. The sensitivity to the weak mixing angle,
neutrino magnetic moment, and a light $Z'$ gauge boson mediator are analyzed. A
Monte Carlo simulation of the backgrounds is performed to assess their
contribution to the signal. The analysis shows that world-leading sensitivities
are achieved with a one-year exposure for a 10 kg chamber at 3 m from a 1
MW$_{th}$ research reactor or a 100 kg chamber at 30 m from a 2000 MW$_{th}$
power reactor. Such a detector has the potential to become the leading
technology to study CE$\nu$NS using nuclear reactors.
