A Deep Learning Method for Computing Eigenvalues of the Fractional Schrodinger Operator

The authors present a novel deep learning method for computing eigenvalues of the fractional Schrodinger operator. The proposed approach combines a newly developed loss function with an innovative neural network architecture that incorporates prior knowledge of the problem. These improvements enable the proposed method to handle both high-dimensional problems and problems posed on irregular bounded domains. The authors successfully compute up to the first 30 eigenvalues for various fractional Schrodinger operators. As an application, the authors share a conjecture to the fractional order isospectral problem that has not yet been studied.
