Abstract
We experimentally demonstrate the strictly nonclassical behavior in a many-atom system using a recently derived criterion [E. Kot, Phys. Rev. Lett. 108, 233601 (2012)PRLTAO0031-900710.1103/PhysRevLett.108.233601] that explicitly does not make use of quantum mechanics. We thereby show that the magnetic-moment distribution measured by McConnell et al. [Nature (London) 519, 439 (2015)NATUAS0028-083610.1038/nature14293] in a system with a total mass of 2.6×105 atomic mass units is inconsistent with classical physics. Notably, the strictly nonclassical behavior affects an area in phase space 103 times larger than the Planck quantum.
