How the Kondo ground state avoids the orthogonality catastrophe
Gerd Bergmann
In the presence of a magnetic impurity the spin-up and down band states are modified differently by the impurity. If the multi-electron scalar product (MESP) between the occupied s…
The Friedel-Anderson and Kondo Impurity Problem for Arbitrary s-Band Density of States and Exchange Interaction
Gerd Bergmann
In his renormalization paper of the Kondo effect Wilson replaced the full band of s-electrons by a small number of ''Wilson states''. He started from a rather artificial symmetric…
Spacial Modulation of the Magnetization in Cobalt Nanowires
Gerd Bergmann, Yaqi Tao, Jia G. Lu +1
Cobalt nanowires with a diameter in the range between 50 to 100nm can be prepared as single-crystal wires with the easy axis (the c-axis) perpendicular to the wire axis. The compet…
The anomalous Hall effect in ferromagnetic Fe: Skew scattering or side jump?
Gerd Bergmann, Manjiang Zhang
The question is investigated whether the anomalous Hall effect (AHE) in Fe films is due to skew scattering or side jump. For this purpose sandwiches of FeIn are investigated in whi…
