Abstract

We present improved constraints on the coupling of ultralight bosonic dark matter to photons based on long-term measurements of two optical frequency ratios. In these optical clock comparisons, we relate the frequency of the \({}^2S_{1/2} (F=0)\leftrightarrow {}^2F_{7/2} (F=3)\) electric-octupole (E3) transition in \(^{171}\)Yb\(^{+}\) to that of the \({}^2S_{1/2} (F=0)\leftrightarrow \,{}^2D_{3/2} (F=2)\) electric-quadrupole (E2) transition of the same ion, and to that of the \({}^1S_0\leftrightarrow\,{}^3P_0\) transition in \(^{87}\)Sr. Measurements of the first frequency ratio \(\nu_\textrm{E3}/\nu_\textrm{E2}\) are performed via interleaved interrogation of both transitions in a single ion. The comparison of the single-ion clock based on the E3 transition with a strontium optical lattice clock yields the second frequency ratio \(\nu_\textrm{E3}/\nu_\textrm{Sr}\). By constraining oscillations of the fine-structure constant \(\alpha\) with these measurement results, we improve existing bounds on the scalar coupling \(d_e\) of ultralight dark matter to photons for dark matter masses in the range of about \( 10^{-24}-10^{-17}\,\textrm{eV}/c^2\). These results constitute an improvement by more than an order of magnitude over previous investigations for most of this range. We also use the repeated measurements of \(\nu_\textrm{E3}/\nu_\textrm{E2}\) to improve existing limits on a linear temporal drift of \(\alpha\) and its coupling to gravity.
