在平衡时,布洛赫壁是具有不同磁化强度的畴之间的手性界面。远离平衡,一组受迫振子可以在具有不同相位的状态之间显示出壁。在这封信中,我们表明,当这些墙成为手征,他们移动的速度简单地与他们的手征。这种令人惊讶的行为是非变分效应的直接结果,这是非平衡系统的典型特征。
At equilibrium, Bloch walls are chiral interfaces between domains with different magnetization. Far from equilibrium, a set of forced oscillators can exhibit walls between states with different phases. In this Letter, we show that when these walls become chiral, they move with a velocity simply related to their chirality. This surprising behavior is a straightforward consequence of nonvariational effects, which are typical of nonequilibrium systems.
