Sridhar and A. Kudrolli [Phys. Rev. Lett. 72, 2175 (1994)] on isospectral cavities built from triangles. A straightforward proof of isospectrality is given, based on the mode-matching method. Our results show that the experiment is accurate to 0.3% for the first 25 states. The level statistics resemble those of a Gaussian orthogonal ensemble when the integrable part of the spectrum is removed. 2011-07-07T12:51:34Z 2011-07-07T12:51:34Z 1995 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: http://dx.doi.org/10.1103/PhysRevE.51.703 Physical Review E, 1995, vol. 51, núm. 1, p. 703-708 http://dx.doi.org/10.1103/PhysRevE.51.703 (c) The American Physical Society, 1995 info:eu-repo/semantics/openAccess The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
