Kondo transport in an anisotropic two-dimensional electron gas with quadratic momentum-dependent spin splitting

M. R. Parymuda

Quadratic spin splitting in an anisotropic 2DEG suppresses the Kondo temperature by ~37% at a critical coupling strength, marking the onset of Kondo collapse.

Claims

C1strongest claim

We identify a critical coupling α_cr marking the onset of a Kondo collapse, at which T_K is reduced by approximately 37% relative to that of the conventional two-dimensional electron gas.

C2weakest assumption

The low-energy effective k·p model with quadratic spin texture remains valid across the range of α studied, and third-order perturbation theory in the s-d exchange coupling suffices to capture the temperature dependence of the resistivity corrections and T_K.

C3one line summary

Quadratic spin splitting in an anisotropic 2DEG suppresses the Kondo temperature by ~37% at a critical coupling strength, marking the onset of Kondo collapse.
