Quantum Spectra and Classical Orbits in Artificial Atom
We define a quantum spectrum function using the eigenvalues and the eigenfunctions in the system of two-dimensional artificial atom. We find that the Fourier transform of the quantum spectrum function reveals a lot of information of the classical closed orbits and the classical opened orbits from one point to another. These results give new evidence about the classical-quantum correspondence.
