  • Title: Instabilities of isotropic solutions of active polar filaments.
    Author: Liverpool TB, Marchetti MC.
    Journal: Phys Rev Lett; 2003 Apr 04; 90(13):138102. PubMed ID: 12689327.
    Abstract:
    We study the dynamics of an isotropic solution of polar filaments coupled by molecular motors which generate relative motion of the filaments in two and three dimensions. We investigate the stability of the homogeneous state for constant motor concentration taking into account excluded volume and an estimate of entanglement. At low filament density the system develops a density instability, while at high density entanglement drives the instability of orientational fluctuations.
