The discoveries of unconventional superconductivity and superfluidity in most condensed matter systems were major advances in physics. There has been a debate between scientists for a long time: which theory leads to a true understanding of these intriguing phenomena? This is the first book devoted to the modern theory (i.e., Bose-liquid theory) of unconventional superconductors and superfluids. The Bose-liquid theory for unconventional superconductors and superfluids is developed beyond the standard Bardeen-Cooper-Schrieffer (BCS) like theories of superfluid Fermi-liquids and the usual theory of Bose-Einstein condensation (BEC) of an ideal Bose gas. This theory is a real breakthrough beyond the usual physics of Fermi liquid superconductivity (superfluidity) and BEC phenomenon. The new findings, concepts and principles of the Bose-liquid theory of unconventional superconductivity and superfluidity are presented. The presented Bose-liquid theory describes consistently all the emerging pseudogap behaviors and novel superconducting/superfluid states and properties of high-Tc cuprates and other related systems. The new theoretical results are compared with experimental findings in many specific cases. The present book is needed for readers and researchers, who should be familiar with the fundamentals of the Bose-liquid theory of unconventional superconductors and superfluids, since it is devoted to the new direction in physics.
Djumanov Safarali was born in 1947 in the Samarkand region of the Republic of Uzbekistan. He graduated at the Faculty of Physics, Samarkand State University, Uzbekistan, 1970. From 1971 to 1974, he was a post-graduate student at this university. From 1975 to 1984, he worked as a junior researcher at the Institute of Nuclear Physics (INP) of the Uzbek Academy of Sciences. From 1984 to 1992, he worked as a senior researcher at the INP of the Uzbek Academy of Sciences. From 1992 to 1999, he worked as the head of the sector of solid-state theory at the INP of the Uzbek Academy of Sciences. From 1999 to the present, he has been chief researcher at the INP of the Uzbek Academy of Sciences.
