Deformation of the Fermi Surface and Anomalous Mass Renormalization by Critical Spin Fluctuations through Asymmetric Spin-Orbit Interaction

Abstract

It is shown that an asymmetric spin-orbit interaction is appreciably renormalized by the effect of critical spin fluctuations. As an explicit example, the Rashba-type interaction is predicted to be suppressed by anti-ferromagnetic critical fluctuations near the hot line (or point), leading to a deformation of the Fermi surface near the hot line (or point) around which the band splitting is decreased, while ferromagnetic critical fluctuations are shown to enhance the Rashba-type interaction everywhere on the Fermi surface, leading to an increase in the band splitting. It is also found that the many-body mass renormalization, which diverges towards the magnetic quantum critical point, is in the opposite sign for the two split bands by the Rashba-type interaction. These predictions are observable by the de Haas-van Alphen (dHvA) effect in principle.
