Dimensional Hausdorff properties of singular continuous spectra [PDF]

open access: yes, 1995
We present an extension of the Gilbert-Pearson theory of subordinacy, which relates dimensional Hausdorff spectral properties of one-dimensional Schrödinger operators to the behavior of solutions of the corresponding Schrödinger equation.

Kato's inequality for magnetic relativistic Schrödinger operators [PDF]

open access: yes, 2016
Kato’s inequality is shown for the magnetic relativistic Schrödinger operator HA, m defined as the operator theoretical square root of the self adjoint, magnetic nonrelativistic Schrödinger operator (−i∇ − A(x))2 + m2 with L 2 loc vector potential A(x)

Some Spectral Properties of Schrödinger Operators on Semi Axis

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
The main aim of this work is to investigate some spectral properties of Schrödinger operators on semi axis. We first present the Schrödinger equation with a piecewise continuous potential function q so that the problem differs from the classical ...

Nonlinear conservation laws for the Schrödinger boundary value problems of second order

open access: yesBoundary Value Problems, 2020
In this paper, we apply a reliable combination of maximum modulus method with respect to the Schrödinger operator and Phragmén–Lindelöf method to investigate nonlinear conservation laws for the Schrödinger boundary value problems of second order.

Spectral properties of periodic systems cut at an angle

open access: yesComptes Rendus. Mathématique, 2021
We consider a semi-periodic two-dimensional Schrödinger operator which is cut at an angle. When the cut is commensurate with the periodic lattice, the spectrum of the operator has the band-gap Bloch structure.

Accurate Semiclassical Spectral Asymptotics for a Two-Dimensional Magnetic Schrödinger Operator [PDF]

open access: yes, 2013
We revisit the problem of semiclassical spectral asymptotics for a pure magnetic Schrödinger operator on a two-dimensional Riemannian manifold. We suppose that the minimal value b0 of the intensity of the magnetic field is strictly positive, and the ...

A Nonlinear Schrödinger Equation Resonating at an Essential Spectrum

open access: yesAdvances in Mathematical Physics, 2016
We consider the nonlinear Schrödinger equation -Δu+f(u)=V(x)u  in  RN. The potential function V satisfies that the essential spectrum of the Schrödinger operator -Δ-V is [0,+∞) and this Schrödinger operator has infinitely many negative eigenvalues ...

Discrete Schrödinger operators and Finsler metric (Spectral and Scattering Theory and Related Topics) [PDF]

open access: yes, 2023
In this article, we review the results in [9] on the Agmon estimate for discrete Schrödinger operators. We first discuss the semiclassical analysis for discrete Schrödinger operators with emphasis on the microlocal analysis on the torus.
