Comparison of energetic shifts and splittings of hybridized Shiba states in a FM-coupled $\sqrt{2}a-\left[1\overline{1}0\right]$ Mn dimer.

Shiba state	Experiment		Theory
	Shift (μV)	Splitting (μV)	Shift (μV)	Splitting (μV)
α	+120	+140	+60	+180
β	−	−	+195	−30
γ	+260	−130	+30	+120
δ	+330	+240	+200	+400

The energetic shifts were calculated from the experimental and theoretical results by $\frac{1}{2}\left(∣E_{n_{\mathrm{a}}}∣+∣E_{n_{\mathrm{s}}}∣\right)-\mid E_n\mid$, where $E_n$ are the energetic positions of the single-adatom Shiba states $n\in \mathrm{(\alpha ,\; \beta ,\; \gamma ,\; \delta )}$, and $E_{n_{\mathrm{a}}}$ and $E_{n_{\mathrm{s}}}$ are the energies of the respective antisymmetric and symmetric Shiba states in the dimer. The splittings of hybridized Shiba states are calculated by $∣E_{n_{\mathrm{s}}}∣-∣E_{n_{\mathrm{a}}}∣$.
