  The process of neutral-current coherent elastic neutrino-nucleus scattering,
consistent with the Standard Model (SM) expectation, has been recently measured
by the COHERENT experiment at the Spallation Neutron Source. On the basis of
the observed signal and our nuclear calculations for the relevant Cs and I
isotopes, the extracted constraints on both conventional and exotic neutrino
physics are updated. The present study concentrates on various SM extensions
involving vector and tensor nonstandard interactions as well as neutrino
electromagnetic properties, with an emphasis on the neutrino magnetic moment
and the neutrino charge radius. Furthermore, models addressing a light sterile
neutrino state and scenarios with new propagator fields---such as vector
$Z^\prime$ and scalar bosons---are examined, and the corresponding regions
excluded by the COHERENT experiment are presented.
