Quantum simulation. Spectroscopic observation of SU(N)-symmetric interactions in Sr orbital magnetism

SU(N) symmetry can emerge in a quantum system with N single-particle spin states when spin is decoupled from interparticle interactions. Taking advantage of the high measurement precision offered by an ultrastable laser, we report a spectroscopic observation of SU(N ≤ 10) symmetry in (87)Sr. By enco...
