A spin-1/2 Anderson impurity in a semiconductor quantum well with Rashba and Dresselhaus spin-orbit couplings is studied by using a variational wavefunction method.The local magnetic moment is found t
Appreciable zero-energy surface bound states are shown to exist in Fe‐pnictide superconductors with antiphase s+‐ wave pairing.In contrast to the [110] bound states in ($)d($)‐wave superconductors,the
We report an unprecedented anisotropic superconductivity in Eu(Fe0.75Ru0.25)2As2single crystals.The in-plane resistivity (ρab) and vertical magnetization (Mc) show a superconducting transition at TSC=
