Ordinary differential equations | Chaotic maps
In dynamics, the Van der Pol oscillator is a non-conservative oscillator with non-linear damping. It evolves in time according to the second-order differential equation: where x is the position coordinate—which is a function of the time t, and μ is a scalar parameter indicating the nonlinearity and the strength of the damping. (Wikipedia).
The Quantum Harmonic Oscillator Part 1: The Classical Harmonic Oscillator
For our third quantum problem we will visit harmonic oscillators. In a classical setting, this is like the ball on a spring we examined when learning about Hooke's law in the classical physics series. But this has quantum application as well, in modeling the vibrations of molecules and thi

Résumé The discovery of the idea of limit cycle by Poincare was based mostly on geometrical considerations. The application to ordinary differential equations can be done analytically in the opposite limits of weak and of strong nonlinearity. In the latter, one finds what are called relax
