Mn. Vrahatis et al., Application of the Characteristic Bisection Method for locating and computing periodic orbits in molecular systems, COMP PHYS C, 138(1), 2001, pp. 53-68
The Characteristic Bisection Method for finding the roots of non-linear alg
ebraic and/or transcendental equations is applied to LiNC/LiCN molecular sy
stem to locate periodic orbits and to construct the continuation/bifurcatio
n diagram of the bend mode family. The algorithm is based on the Characteri
stic Polyhedra which define a domain in phase space where the topological d
egree is not zero. The results are compared with previous calculations obta
ined by the Newton Multiple Shooting algorithm. The Characteristic Bisectio
n Method not only reproduces the old results, but also, locates new symmetr
ic and asymmetric families of periodic orbits of high multiplicity. (C) 200
