Abstract
The influence of Thomas - Rashba precession on the physics of Kondo tunneling through quantum dots is analyzed. It is shown that this precession is relevant only at finite magnetic fields. Thomas - Rashba precession results in peculiar anisotropy of the effective g-factor and initiates dephasing of the Kondo tunneling amplitude at low temperature, that is strongly dependent on the magnetic field.
