This concerns perturbation theory and constructive determination of the spectral invariants and finding the periodic potential from the given Bloch eigenvalues. The unique method of this book derives the asymptotic formulas for Bloch eigenvalues and Bloch functions for arbitrary dimension. Moreover, the measure of the iso-energetic surfaces in the high energy region is construct and estimated. It implies the validity of the Bethe-Sommerfeld conjecture for arbitrary dimensions and arbitrary lattices. Using the perturbation theory constructed in this book, the spectral invariants of the multidimensional operator from the given Bloch eigenvalues are determined. Some of these invariants are explicitly expressed by the Fourier coefficients of the potential. This way the possibility to determine the potential constructively by using Bloch eigenvalues as input data is given. In the end an algorithm for the unique determination of the potential is given.Springer Tracts in Modern Physics,0081-3869 ;263Quantum theorySolid state physicsMathematical physicsQuantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Solid State Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25013Mathematical Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/M35000Quantum theory.Solid state physics.Mathematical physics.Quantum Physics.Solid State Physics.Mathematical Physics.515.724Veliev Oktayauthttp://id.loc.gov/vocabulary/relators/aut792319MiAaPQMiAaPQMiAaPQBOOK9910300423203321Multidimensional Periodic Schrödinger Operator1771629UNINA
