Neutrino nucleus elastic scattering is an electroweak interaction of the Standard Model of particle physics. We formulate a quantitative and universal parametrization of the quantum mechanical coherency effects in neutrino nucleus elastic scattering, under which the experimentally accessible misalignment phase angle between nonidentical nucleonic scattering centers can be studied. We relate it to the conventional description of nuclear many-body physics through form factor and data-driven cross-section reduction fraction. We present the limits on first observation from CsI and LAr data from COHERENT collaboration along with prospects of observing the neutrino nucleus elastic scattering process from the reactor and solar neutrinos with a variety of nuclear targets at the sub-keV threshold.
