本文研究了由外部非均匀场$h({bf r},t)$产生的三维Ising系统中界面的结构。$h$改变任意方向的二维平面上的符号。当场被速度${\bf v}_e$(即$H({\bf r},t)=H({\bf r-v_e}t)$)拉动时,界面经历了几个动力学转变。对于低速,它被场廓线牵制并随场廓线移动,局部斜坡的分布经历了一系列公度-不公度转换。对于大的${\bf v}_e$,界面解钉并随KPZ指数增长。

英文摘要:
We study the structure of an interface in a three dimensional Ising system created by an external non-uniform field $H({\bf r},t)$. $H$ changes sign over a two dimensional plane of arbitrary orientation. When the field is pulled with velocity ${\bf v}_e$, (i.e. $H({\bf r},t) = H({\bf r - v_e}t)$), the interface undergoes a several dynamical transitions. For low velocities it is pinned by the field profile and moves along with it, the distribution of local slopes undergoing a series of commensurate-incommensurate transitions. For large ${\bf v}_e$ the interface de-pinns and grows with KPZ exponents.
