Pavel Stránský - Errors in the calculation of the eigenstates

http://www.pavelstransky.cz/errors_quant_a0.php

Err (Estimate of A0). Last updated: 20.7.2016. Errors in the calculation of the eigenstates. Figure 1: Trace of the Hamiltonian matrix. The Hamiltonian matrix is constructed in the oscillator basis with a parameter A. 0 The best value is A. 0min/2 (it roughly corresponds with the position of the minimum of the trace). Figure 2: Energy versus the ordering number of the energy level. Various lines correspond to various A. 0 have the same value. Figure 3: Eigenvector convergence. Figure 4: Peres lattices.

Err (Estimate of A0). Last updated: 20.7.2016. Energy levels and wave functions. E(38) = -0.00012. Rsaquo;››. Figure 1: 150 lowest energy levels. Section γ=0 of the potential energy surface is drawed by the yellow curve. The blue thick line indicates the selected level; the orange thick line corresponds with the energy above that the chaotic dynamics appears. The red curves show the lowest energy states in the harmonic approximation of the bottom of the potential. Figure 2: Peres lattice of operator L.
