Phys. Rev. Lett. 78, 4510–4513 (1997)Spontaneous Oscillations of Collective Molecular MotorsReceived 19 November 1996; published in the issue dated 9 June 1997 We present a physical mechanism which can lead to oscillatory motion of molecular motors cooperating in large groups when the system is elastically coupled to its environment. Analytical and numerical calculations reveal a characteristic type of oscillatory behavior with cusplike extrema. Typical oscillation frequencies are determined by the internal time scales of the motors. The physical mechanism we describe generates in a natural way many of the characteristic properties of spontaneous oscillations observed in some muscles and myofibrils. © 1997 The American Physical Society URL:
