From antiferromagnetic and hidden order to Pauli paramagnetism in UM2Si2 compounds with 5f electron duality

Using inelastic X-ray scattering beyond the dipole limit and hard X-ray photoelectron spectroscopy we establish the dual nature of the U 5f electrons in UM2Si2 (M = Pd, Ni, Ru, Fe), regardless of their degree of delocalization. We have observed that the compounds have in common a local atomic-like s...

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.)...
