Luchinsky, D. G. and McClintock, Peter V.E. and Soskin, Stanislav M. and Stein, N. D. and Neiman, N. D. (1996) Comment on "Nonlinear resonance and chaos in the relativistic phase space for driven nonlinear systems". Physical Review E, 53 (4). pp. 4240-4241. ISSN 1539-3755
Kim and Lee (Phys. Rev. E 52, 473; 1995) report relativity-induced resonances in periodically driven oscillators. We comment that zero-dispersion nonlinear resonance (ZDNR) will occur in some of the systems considered, outline the physical origins of the ZDNR, and propose an explanation of a discrepancy noted by Kim and Lee between their theoretical and numerical values of the energy at the stationary stable points of Poincare sections.
