Accidental degeneracy and hidden symmetry: Rectangular wells with commensurate sides. American Journal of Physics, 66 (7), 629-631.0002-9505http://hdl.handle.net/11441/58306Two-dimensional quantum square wells and rectangular billiards with commensurate sides are simple systems which exhibit accidental degeneracies. We show that a recent analysis for square wells can be similarly applied to rectangular wells with commensurate sidesapplication/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1119/1.18917
