摘要: An introduction to the theory of heavy-fermion systems is given. Emphasis put on physical arguments which accompany various theoretical models rather than presenting latter in all details. After an subject, ground state and description heavy quasiparticles are discussed. The origin low-lying excitations considered detail. This followed by a discussion quasiparticle interactions. interaction with phonons studied extensively. Of particular interest hydrodynamic regime for density fluctuations presented. Finally superconductivity Special attention paid pairing interactions nature pair state.
