  Present and prospective fundamental symmetry tests with nucleons, nuclei and
atoms are probing for possible new physics at the TeV scale and beyond. These
ongoing and proposed table-top as well as accelerator-based experiments are
thus a vital component of the Intensity Frontier. At the same time, these tests
provide increasingly sophisticated probes of long-distance strong interactions
that are responsible for the structure of nucleons and nuclei. In this
community report, some of the most compelling opportunities with nucleons,
nuclei and atoms are summarized, drawing largely on input received from the
nuclear and atomic physics communities. In particular, this report includes
many contributions submitted to two recent Intensity Frontier Workshops.
