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.)...
