Predicted Superconductivity in Sn:Si(111) found experimentally

Employing advanced methods in quantum many-body theory in 2018 we predicted chiral d-wave superconductivity in correlated ad-atom lattices on the Si(111) surface (X. Cao et al.). Now, two years later,  experimentalists in Tennessee have found superconductivity in hole doped Sn:Si(111) (X. Wu et al.). The symmetry of the order parameter still needs to be clarified and the observed critical temperatures are with Tc~4-5K quite low. According to our calculations, however, a significant increase of Tc should be possible at higher doping levels.
