(xiv, 301 pages 24cm. Aimed at graduate students and researchers, this book covers the key aspects of the modern quantum theory of solids, including up-to-date ideas such as quantum fluctuations and strong electron correlations. It presents in the main concepts of the modern quantum theory of solids, as well as a general description of the essential theoretical methods required when working with these systems. Diverse topics such as general theory of phase transitions, harmonic and anharmonic lattices, Bose condensation and superfluidity, modern aspects of magnetism including resonating valence bonds, electrons in metals, and strong electron correlations are treated using unifying concepts of order and elementary excitations. The main theoretical tools used to treat these problems are introduced and explained in a simple way, and their applications are demonstrated through concrete examples"--Provided by publisher Some basic notions of the classical and quantum statistical physics -- General theory of phase transitions -- Bose- and Fermi-statistics -- Phonons in crystals -- General Bose-systems : Bose-condensation -- Magnetism -- Electrons in metals -- Interacting electrons : Green functions and Feynman diagrams (methods of the field theory in many-particle physics) -- Electrons with Coulomb interaction -- Fermi-liquid theory and its possible generalizations -- Instabilities and phase transitions in electronic systems -- Strongly correlated electrons -- Magnetic impurities in metals, Kondo effect, heavy fermions and mixed valence. / Daniel Khomskii Physics Solid state physics Quantum theory Physical Phenomena Electrons Science -- Condensed Matter Quantentheorie 530.41 KHO 9780521835213 :Zafaa Books & Distributors :313/56F 49A, Anand Nagar Inderlok Delhi 110035 220113 20220216124256.0
