Field-induced suppression of the heavy-fermion state in YbRh₂Si₂.

Gertrud Zwicknagl1.   

Abstract

We present calculations of the magnetic-field-induced changes of the heavy quasiparticles in YbRh2Si2 which are reflected in thermodynamic and transport properties. The quasiparticles are determined by means of the renormalized band method. The progressive de-renormalization of the quasiparticles in the magnetic field is accounted for using field-dependent quasiparticle parameters deduced from numerical renormalization group studies. Consequences for the interpretation of experimental data are discussed.
