Coherent excitation of a $\mu$Hz scale optical magnetic quadrupole transition

V. Klüsener, S. Pucher, D. Yankelev +7

We report on the coherent excitation of the ultranarrow ${}^1{\mathrm{S}}_0$-${}^3{\mathrm{P}}_2$ magnetic quadrupole transition in ${}^{88}\mathrm{Sr}$. By confining atoms in a state in…
