Abstract

We demonstrate that the main universal features of the low temperature magnetic field-temperature experimental phase diagram of CeCoIn₅ and other heavy-fermion metals can be well explained within the concept of quasiparticles and fermion condensation quantum phase transition. We analyze dynamic conductance recently obtained in measurements on CeCoIn₅ and show that the particle-hole symmetry is violated in this metal making dynamic conductance asymmetric as a function of applied voltage V.
