  Understanding symmetry-breaking states of materials is a major challenge in
the modern physical sciences. Quantum atmosphere proposed recently sheds light
on the hidden world of these symmetry broken patterns. But the requirements for
exquisite sensitivity to the small shift and tremendous spatial resolution to
local information pose huge obstacles to its experimental manifestation. In our
experiment, we prepare time-reversal-symmetry conserved and broken quantum
atmosphere of a single nuclear spin and successfully observe their symmetry
properties. Our work proves in principle that finding symmetry patterns from
quantum atmosphere is conceptually viable. It also opens up entirely new
possibilities in the potential application of quantum sensing in material
diagnosis.
