Spin-anisotropic magnetic impurity in a Fermi gas: Integration of poor man's scaling equations

We consider a single magnetic impurity described by the spin-anisotropic s-d(f ) exchange (Kondo) model and formulate a scaling equation for the spin-anisotropic model when the density of states (DOS) of electrons is a power-law function of energy (measured relative to the Fermi energy).We solve this equation containing terms up to the second order in coupling constants in terms of elliptic functions. From the obtained solution we find the phases corresponding to the infinite isotropic antiferromagnetic Heisenberg exchange, to the impurity spin decoupled from the electron environment (only for the pseudogap DOS), and to the infinite Ising exchange (only for the diverging DOS). We analyze the critical surfaces, corresponding to the finite isotropic antiferromagnetic Heisenberg exchange for the pseudogap DOS.

Physik-Bachelor und -Master reakkreditiert

On the basis of the successful on-site review meeting in December 2015, the accreditation of our B.Sc. and M.Sc. 'Physics' was extended by ASIIN, thereby confirming the high quality of our study programs. - Meanwhile (as of 30 Sep 2016) the accreditation was extended until 2022, i.e., the maximally possible duration.
