Nodal algebraic curves and entropy diagnostics in degenerate two-dimensional harmonic-oscillator shells
C A Escobar Ruiz, H Olivares-Pilon, A M Escobar-Ruiz
Degeneracy allows the nodal structure of a quantum state to vary without changing its energy. We study this effect for real superpositions in the fixed-energy shells of the two-dim…

Classical-quantum study of confinement in the chaotic Yang-Mills Hamiltonian
Mario A. Quiroz-Juarez, Marco A. Zurita, Horacio Olivares-Pilon +1
We analyze how quantum mechanics reinstates confinement in Hamiltonian systems that are classically unstable and exhibit chaotic dynamics. Specifically, we consider two paradigmati…
