Schrödinger operators with n positive eigenvalues: an explicit construction involving complex valued potentials
نویسندگان
چکیده
An explicit construction is provided for embedding n positive eigenvalues in the spectrum of a Schrödinger operator on the half-line with a Dirichlet boundary condition at the origin. The resulting potential is of von Neumann-Wigner type, but can be real valued as well as complex valued.

We derive a sharp bound on the location of non-positive eigenvalues of Schrödinger operators on the halfline with complex-valued potentials.
متن کاملNumber of Eigenvalues for a Class of Non-selfadjoint Schrödinger Operators
In this article, we prove the finiteness of the number of eigenvalues for a class of Schrödinger operators H = −∆ + V (x) with a complex-valued potential V (x) on R, n ≥ 2. If IV is sufficiently small, IV ≤ 0 and IV 6= 0, we show that N(V ) = N(RV )+k, where k is the multiplicity of the zero resonance of the selfadjoint operator−∆+RV and N(W ) the number of eigenvalues of −∆+W , counted accordi...
متن کاملA weak Gordon type condition for absence of eigenvalues of one-dimensional Schrödinger operators
We study one-dimensional Schrödinger operators with complex measures as potentials and present an improved criterion for absence of eigenvalues which involves a weak local periodicity condition. The criterion leads to sharp quantitative bounds on the eigenvalues. We apply our result to quasiperiodic measures as potentials. MSC2010: 34L15, 34L40, 81Q10, 81Q12
متن کاملNumber of Complex Eigenvalues for a Class of Dissipative Schrödinger Operators
For a class of dissipative Schrödinger operators H = −∆ + V (x) with a complex-valued potential V = V1−iV2 with V2 ≥ 0 and |V (x)| = O(|x| ) as |x| tends to infinity, we prove that the complex eigenvalues of H can not accumulate to zero. In the perturbation regime where V2 is sufficiently small, we show under some conditions that N(V ) = N(V1)+k, where k is the multiplicity of the zero resonanc...
متن کاملEigenvalue Bounds for Schrödinger Operators with Complex Potentials. Ii Rupert L. Frank and Barry Simon
Laptev and Safronov conjectured that any non-positive eigenvalue of a Schrödinger operator −∆+ V in L(R) with complex potential has absolute value at most a constant times ‖V ‖ γ+ν/2 for 0 < γ ≤ ν/2 in dimension ν ≥ 2. We prove this conjecture for radial potentials if 0 < γ < ν/2 and we ‘almost disprove’ it for general potentials if 1/2 < γ < ν/2. In addition, we prove various bounds that hold,...
