Shiba multiplets due to Mn impurities in MgB_2
Catalin Pascu Moca, Gergely Zarand, Eugene Demler +1
We study the effect of magnetic Mn ions on the two-band superconductor MgB_2, and compute both the total and spin resolved scanning tunneling spectrum in the vicinity of the magnet…
Quantum Magnetic Impurities in Magnetically Ordered Systems
A. H. Castro Neto, E. Novais, L. Borda +2
We discuss the problem of a spin 1/2 impurity immersed in a spin S magnetically ordered background. We show that the problem maps onto a generalization of the dissipative two level…
Orbital Kondo behavior from dynamical structural defects
L. Borda, A. Zawadowski, G. Zarand
The interaction between an atom moving in a model double-well potential and the conduction electrons is treated using renormalization group methods in next-to-leading logarithmic o…
