Alternative Fourier-series approach to nonlinear oscillations
Francisco M. Fernández
We propose an alternative approach that avoids the nonlinear equations for the Fourier coefficients that appear in the method of harmonic balance. We apply it to two simple illustr…

Charm spectroscopy beyond the constituent quark model
J. Segovia, D. R. Entem, F. Fernández
We study the nature of the new charm and charmonium like states observed in the last few years, using a constituent quark model with an screened confinement potential. In the open…
