Parasupersymmetry in Quantum Graphs
arXiv:1210.7801 · doi:10.1016/j.aop.2013.01.007
Abstract
We study hidden parasupersymmetry structures in purely bosonic quantum mechanics on compact equilateral graphs. We consider a single free spinless particle on the graphs and show that the Huang-Su parasupersymmetry algebra is hidden behind degenerate spectra.
