Functional renormalization and mean-field approach to multiband systems with spin-orbit coupling: application to the Rashba model with attractive interaction

Show other versions (1)

The functional renormalization group (RG) in combination with Fermi surface patching is a well-established method for studying Fermi liquid instabilities of correlated electron systems. In this paper, we further develop this method and combine it with mean-field theory to approach multiband systems...

Description
Summary:The functional renormalization group (RG) in combination with Fermi surface patching is a well-established method for studying Fermi liquid instabilities of correlated electron systems. In this paper, we further develop this method and combine it with mean-field theory to approach multiband systems with spin-orbit coupling, and we apply this to a tight-binding Rashba model with an attractive, local interaction.
