Quasiparticles and quantum phase transition in universal low-temperature properties of heavy-fermion metals
Quasiparticles and quantum phase transition in universal low-temperature properties of heavy-fermion metals
We demonstrate, that the main universal features of the low temperature experimental $H-T$ phase diagram of CeCoIn5 and other heavy-fermion metals can be well explained using Landau paradigm of quasiparticles. The main point of our theory is that above quasiparticles form so-called fermion-condensate state, achieved by a fermion condensation quantum …
