TitleMultidimensional Periodic Schr??dinger Operator : Perturbation Theories for High Energy Regions and Their Applications
Author(s)Veliev, Oktay
PublicationCham, 1. Imprint: Springer 2. Springer International Publishing, 2024.
DescriptionXIII, 411 p. 1 illus : online resource
Abstract NoteThis book describes the direct and inverse problems of the multidimensional Schr??dinger operator with a periodic potential, a topic that is especially important in perturbation theory, constructive determination of spectral invariants and finding the periodic potential from the given Bloch eigenvalues. It provides a detailed derivation of the asymptotic formulas for Bloch eigenvalues and Bloch functions in arbitrary dimensions while constructing and estimating the measure of the iso-energetic surfaces in the high-energy regime. Moreover, it presents a unique method proving the validity of the Bethe???Sommerfeld conjecture for arbitrary dimensions and arbitrary lattices. Using the perturbation theory constructed, it determines the spectral invariants of the multidimensional operator from the given Bloch eigenvalues. Some of these invariants are explicitly expressed by the Fourier coefficients of the potential, making it possible to determine the potential constructively using Bloch eigenvalues as input data. Lastly, the book presents an algorithm for the unique determination of the potential. This updated and significantly expanded third edition features an extension of this framework to all dimensions, offering a now complete theory of self-adjoint Schr??dinger operators within periodic potentials. Drawing from recent advancements in mathematical analysis, this edition delves even deeper into the intricacies of the subject. It explores the connections between the multidimensional Schr??dinger operator, periodic potentials, and other fundamental areas of mathematical physics. The book's comprehensive approach equips both students and researchers with the tools to tackle complex problems and contribute to the ongoing exploration of quantum phenomena

TitleNon-self-adjoint Schr??dinger Operator with a Periodic Potential
Author(s)Veliev, Oktay
PublicationCham, Springer International Publishing, 2021.
DescriptionX, 294 p. 10 illus., 9 illus. in color : online resource
Abstract NoteThis book gives a complete spectral analysis of the non-self-adjoint Schr??dinger operator with a periodic complex-valued potential. Building from the investigation of the spectrum and spectral singularities and construction of the spectral expansion for the non-self-adjoint Schr??dinger operator, the book features a complete spectral analysis of the Mathieu-Schr??dinger operator and the Schr??dinger operator with a parity-time (PT)-symmetric periodic optical potential. There currently exists no general spectral theorem for non-self-adjoint operators; the approaches in this book thus open up new possibilities for spectral analysis of some of the most important operators used in non-Hermitian quantum mechanics and optics. Featuring detailed proofs and a comprehensive treatment of the subject matter, the book is ideally suited for graduate students at the intersection of physics and mathematics

TitleMultidimensional Periodic Schr??dinger Operator : Perturbation Theory and Applications
Author(s)Veliev, Oktay
PublicationCham, Springer International Publishing, 2015.
DescriptionX, 242 p : online resource
Abstract NoteThe book describes the direct problems and the inverse problem of the multidimensional Schr??dinger operator with a periodic potential. 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
