小母马

Book 1997inear terms in the energy dispersion can be systematically included into bosonization in arbitrary .d., so that in .d.1 the curvature of the Fermi surface can be taken into account. Part II gives applications to problems of physical interest. The book addresses researchers and graduate students in theoretical condensed matter physics.

We develop a general formalism for obtaining corrections to the Gaussian approximation,

For regular interactions (η = 0) in one dimension it is possible to calculate the full Debye-Waller factor Q.(.,τ) if a certain cutoff procedure is adopted. Then we reproduce the well-known bosonization result for the Tomonaga-Luttinger model.

However, Luttinger liquid behavior in three dimensions can be due to quasi-one-dimensional anisotropy in the electronic band structure or in the phonon frequencies. A brief account of the results presented in this chapter has been published in [.].
