The fundamental gap for a one-dimensional Schrödinger operator with Robin boundary conditions

چکیده
For Schrödinger operators on an interval with either convex or symmetric single-well potentials and Robin Neumann boundary conditions, the gap between two lowest eigenvalues is minimized when potential constant. We also have results for p p -Laplacian.

Artificial boundary conditions for one-dimensional cubic nonlinear Schrödinger equations
This paper addresses the construction of nonlinear integro-differential artificial boundary conditions for one-dimensional nonlinear cubic Schrödinger equations. Several ways of designing such conditions are provided and a theoretical classification of their accuracy is given. Semi-discrete time schemes based on the method developed by Durán and Sanz-Serna [IMA J. Numer. Anal. 20 (2) (2000), pp...
متن کاملEigenvalue Problems for One-Dimensional Discrete Schrödinger Operators with Symmetric Boundary Conditions
In this paper, we investigate the one-dimensional discrete Schrödinger equation with general, symmetric boundary conditions. Our results primarily concern the number of energy states lying in the wells.
متن کاملThe Fundamental Gap and One-Dimensional Collapse
This equation arises from physics by separating the time and space variables in the wave equation, and the eigenvalues correspond to the frequencies of standing waves on Ω. The set of all eigenvalues is known as the spectrum. Based on the physical interpretation Marc Kac posed the now well-known question, “Can one hear the shape of a drum?” [21]. The mathematical formulation is: if two Euclidea...
متن کاملOn the Numerical Solution of One Dimensional Schrodinger Equation with Boundary Conditions Involving Fractional Differential Operators
In this paper we study of collocation method with Radial Basis Function to solve one dimensional time dependent Schrodinger equation in an unbounded domain. To this end, we introduce artificial boundaries and reduce the original problem to an initial boundary value problem in a bounded domain with transparent boundary conditions that involves half order fractional derivative in t. Then in three...
متن کاملThe Saint-Venant inequality for the Laplace operator with Robin boundary conditions∗
This survey paper is focused on the Saint-Venant inequality for the Laplace operator with Robin boundary conditions. In a larger context, we make the point on the recent advances concerning isoperimetric inequalities of Faber-Krahn type for elastically supported membranes and describe the main ideas of their proofs in both contexts of rearrangement and free discontinuity techniques.
