Sturm-Schrödinger equations: formula for metric

چکیده
Sturm-Schrödinger equations Hψ = EWψ with H 6= H andW 6=W † 6= I are considered, with a weak point of the theory lying in the purely numerical matrix-inversion form of the double-series definition of the necessary metric operator Θ in the physical Hilbert space of states [M. Znojil, J. Phys. A: Math. Theor. 41 (2008) 215304]. This shortcoming is removed here via an amended, single-series definition of Θ. keywords: cryptohermiticity, Sturm-Schrödinger bound-state problem PACS: 03.65.Bz, 03.65.Ca

Inverse Sturm-Liouville problems with transmission and spectral parameter boundary conditions
This paper deals with the boundary value problem involving the differential equation ell y:=-y''+qy=lambda y, subject to the eigenparameter dependent boundary conditions along with the following discontinuity conditions y(d+0)=a y(d-0), y'(d+0)=ay'(d-0)+b y(d-0). In this problem q(x), d, a , b are real, qin L^2(0,pi), din(0,pi) and lambda is a parameter independent of x. By defining a new...
متن کاملThe numerical values of the nodal points for the Sturm-Liouville equation with one turning point
An inverse nodal problem has first been studied for the Sturm-Liouville equation with one turning point. The asymptotic representation of the corresponding eigenfunctions of the eigenvalues has been investigated and an asymptotic of the nodal points is obtained. For this problem, we give a reconstruction formula for the potential function. Furthermore, numerical examples have been established a...
متن کاملPT −symmetric Sturmians
Sturmian bound states emerging at a fixed energy and numbered by a complete set of real eigencouplings λn are considered. For Sturm-Schrödinger equations which are manifestly non-Hermitian we outline the way along which the correct probabilistic interpretation of the system can constructively be re-established via a new formula for the metric. PT −symmetrized Coulomb potential is chosen for ill...

In this paper, the asymptotic representation of the corresponding eigenfunctions of the eigenvalues has been investigated. Furthermore, we obtain the zeros of eigenfunctions.
متن کاملDeterminant of the Schrödinger Operator on a Metric Graph
In the paper, we derive a formula for computing the determinant of a Schrödinger operator on a compact metric graph. This formula becomes very explicit in the case of the Laplacian with the Neumann boundary conditions.
