Chapman-Enskog method and synchronization of globally coupled oscillators | L.L. Bonilla
; | Date: |
12 Jun 2000 | Journal: | Phys. Rev. E 62, 4862-4868 (2000) | Subject: | Statistical Mechanics | cond-mat.stat-mech | Abstract: | The Chapman-Enskog method of kinetic theory is applied to two problems of synchronization of globally coupled phase oscillators. First, a modified Kuramoto model is obtained in the limit of small inertia from a more general model which includes ``inertial’’ effects. Second, a modified Chapman-Enskog method is used to derive the amplitude equation for an O(2) Takens-Bogdanov bifurcation corresponding to the tricritical point of the Kuramoto model with a bimodal distribution of oscillator natural frequencies. This latter calculation shows that the Chapman-Enskog method is a convenient alternative to normal form calculations. | Source: | arXiv, cond-mat/0006195 | Services: | Forum | Review | PDF | Favorites |
