Extended Data Fig. 3: Anisotropy of the internal fields in an s + is superconductor.
From: Superconductivity with broken time-reversal symmetry inside a superconducting s-wave state

Two orthogonal components of the normalized internal spontaneous fields Bint/Bc2 depending on a strength of the variation of the SC coupling constant Δη2 due to an inhomogeneity. Inset: Δη2 dependence of the anisotropy ratio of the internal fields γint. In the main text Δλ ≡ aΔη2 with a ~ 1 (see section 6 in the Supplementary information for details).
