The detection of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) performed in 2017 and 2021 with cesium iodide and in 2020 with liquid argon by the COHERENT collaboration has paved the way for precision phenomenological measurements of many diverse physical phenomena.
CEνNS is a neutral current process induced by the exchange of a Z boson that permits to put interesting constraints on nuclear physics, neutrino electromagnetic properties but it also represents a sensitive probe for non-standard interactions (NSI) that are not included in the SM, induced by yet to be discovered neutral vector and scalar bosons.
Recently, CEνNS has also been observed for the first time using antineutrinos from reactors at the Dresden-II site with a germanium detector called NCC-1701, allowing to obtain more stringent and complementary constraints.

In this talk, I will present an overview of the physics reach of CEνNS, presenting, in particular, the state of the art of the constraints on neutrino charge radii, milli-charges, and magnetic moments as well as new limits on NSI and different new physics models involving light vector Z' mediators. Complementarity of CEνNS constraints with nuclear physics with the recent PREX and CREX neutron-skin determinations will also be discussed, highlighting the interplay with the weak-mixing angle determination.
I will compare all the results obtained with the limits derived from other oscillation and scattering experiments and provide prospects for the future, given the large amount of CEνNS experiments that are currently being proposed or under construction.
