Strongly correlated Fermi systems. A new state of matter (Q2192970)

The book is devoted to properties of strongly correlated Fermi systems (SCFS), such as heavy fermion (HF) metals, quantum spin liquids, quasicrystals, and two-dimensional (2D) systems, which are considered as a new state of matter. The introduced new state of matter is obtained by demonstrating the universal behaviour of the thermodynamic, transport, and relaxation properties. The book presents theoretical evolutions with arguments based on experimental results that very different SCFC have a universal behaviour induced by fermion condensation quantum phase transition (FCQPT). The book discusses general mechanisms leading to the formation of flat bands and studies the common properties of SCFS. Moreover, the authors consider high-\(T_c\) superconductors within a coarse-grained model based on the FCQPT theory, to illuminate their generic relationship with HF metals. To show the ubiquitous features of FCQPT the authors consider its possible role in the emergence of the Universe. Using the model of a homogeneous HF liquid the universal behaviour of high-\(T_c\) superconductors, HF metals, quasicrystals, quantum spin liquids, and 1D and 2D Fermi systems at low temperatures are studied. Moreover, using the FCQPT theory the universal properties of HF compounds systems are discussed. The book contains many results which will be interesting for researchers in the field of condensed matters physics.
