Abstract
We investigate the flux-dependent Kondo temperature in a quantum wire with local Rashba and Coulomb interactions in the Kondo regime, based on the combination of nonequilibrium Green's function and slave-boson methods. It is found that the Kondo temperature of the device strongly depends on the Rashba phase. When the Rashba phase is equal to π 2 , one can deduce an analytic expression which is similar to the Kondo temperature for a quantum dot connected to electronic reservoirs.
