Currents induced by magnetic impurities in superconductors with spin-orbit coupling
Sergey S. Pershoguba, Kristofer Björnson, Annica M. Black-Schaffer +1
We show that superconducting currents are generated around magnetic impurities and ferromagnetic islands proximity-coupled to superconductors with finite spin-orbit coupling. Using…
Absence of the polar Kerr effect in the helical loop-current model [Phys. Rev. Lett. 111, 047005 (2013)]
Sergey S. Pershoguba, Kostyantyn Kechedzhi, Victor M. Yakovenko
We correct our claim made in Phys. Rev. Lett. 111, 047005 (2013) that the chiral texture of loop currents can explain the experimentally observed polar Kerr effect in cuprates. Alt…
Shockley model description of surface states in topological insulators
Sergey S. Pershoguba, Victor M. Yakovenko
We show that the surface states in topological insulators can be understood based on a well-known Shockley model, a one-dimensional tight-binding model with two atoms per elementar…
