| * ABSTRACT | |||||||
| We consider the directed polymer in random potential with an external driving force (or an attractive potential). The moving velocity v of the polymer is monitored as a function of the strength of the external field h. We find a relation between v and h on the creeping regime. The relation between our results and the domain wall movement in the ferroelectric material is discussed. | |||||||
