In Part I he clearly illustrates the approximations and limitations inherent in higher-dimensional bosonization and derives the precise relation with diagrammatic perturbation theory. He shows how the non-linear terms in the energy dispersion can be systematically included into bosonization in arbitrary d, so that in d\u0026gt;1 the curvature of the Fermi surface can be taken into account. Part II gives applications to problems of physical interest, such as coupled metallic chains, electron-phonon interactions, disordered electrons, and electrons coupled to transverse gauge fields. The book addresses researchers and graduate students in theoretical condensed matter physics.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45277970530455,"sku":"9783662141694","price":3633.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783662141694.webp?v=1769289698","url":"https:\/\/atlanticbooks.com\/products\/bosonization-of-interacting-fermions-in-arbitrary-dimensions-9783662141694","provider":"Atlantic Books","version":"1.0","type":"link"}
