The generic fixed point model for pseudo-spin-1/2 quantum dots in nonequilibrium: Spin-valve systems with compensating spin polarizations
Stefan Göttel, Frank Reininghaus, Herbert Schoeller
We study a pseudo-spin-1/2 quantum dot in the cotunneling regime close to the particle-hole symmetric point. For a generic tunneling matrix we find a generic fixed point with inter…

Critical scales in anisotropic spin systems from functional renormalization
Stefan Göttel, Sabine Andergassen, Carsten Honerkamp +2
We apply a recently developed functional renormalization group (fRG) scheme for quantum spin systems to the spin-1/2 antiferromagnetic XXZ model on a two-dimensional square lattice…
