Three-dimensional magnetic Schrödinger operator with the potential supported in a tube
In this paper, we study the following magnetic Schrödinger operator in \(\mathbb {R}^3\):
$$H=(i \nabla +A)^2- \tilde{V},$$
where \(\tilde{V}\) is non-negative potential supported over the tube built along a curve which is a local deformation of a straight one, and \(B:=\textrm{curl}(A)\) is a non-zero and local (i.e., a compact supported) magnetic field. We prove that the magnetic field does not alter the essential spectrum of this system and establish a sufficient condition for the discrete spectrum to be empty.
期刊介绍:
Annals of Functional Analysis is published by Birkhäuser on behalf of the Tusi Mathematical Research Group.
Ann. Funct. Anal. is a peer-reviewed electronic journal publishing papers of high standards with deep results, new ideas, profound impact, and significant implications in all areas of functional analysis and all modern related topics (e.g., operator theory). Ann. Funct. Anal. normally publishes original research papers numbering 18 or fewer pages in the journal’s style. Longer papers may be submitted to the Banach Journal of Mathematical Analysis or Advances in Operator Theory.
Ann. Funct. Anal. presents the best paper award yearly. The award in the year n is given to the best paper published in the years n-1 and n-2. The referee committee consists of selected editors of the journal.
