This book explains modern and interesting physics in heavy-fermion (HF) compounds to graduate
students and researchers in condensed matter physics. It presents a theory of heavy-fermion
(HF) compounds such as HF metals quantum spin liquids quasicrystals and two-dimensional Fermi
systems. The basic low-temperature properties and the scaling behavior of the compounds are
described within the framework of the theory of fermion condensation quantum phase transition
(FCQPT). Upon reading the book the reader finds that HF compounds with quite different
microscopic nature exhibit the same non-Fermi liquid behavior while the data collected on very
different HF systems have a universal scaling behavior and these compounds are unexpectedly
uniform despite their diversity. For the reader's convenience the analysis of compounds is
carried out in the context of salient experimental results. The numerous calculations of the
non-Fermi liquid behavior thermodynamic relaxation and transport properties being in good
agreement with experimental facts offer the reader solid grounds to learn the theory's
applications. Finally the reader will learn that FCQPT develops unexpectedly simple yet
completely good description of HF compounds.
