Dynamics of two polarized nanoparticles*
Duan Xiao-Yonga),b), Wang Zhi-Guoa)
       
The two nanorods are antiparallel and attract each other. The initial angles are θ = π /2, φ = 0, α = π /2, and β = 3 π /4. (a) The distance r as a function of time t . (b) The linear velocity υ and acceleration a as functions of time t . (c) The polar angle θ and azimuth angle φ as functions of time t . (d) The polar angular velocity ω θ and azimuth angular velocity ω φ as functions of time t . (e) The nutation angle α and precession angle β as functions of time t . (f) The nutation angular velocity ω α and precession angular velocity ω β as functions of time t .
