论文摘要
我们表明,在存在噪声的情况下,活跃的2D晶状体中的位错总是没有结合,这意味着在$ d = 2 $中的非零噪声不存在主动近晶相。通过施加旋转对称性断裂场,可以像2D中的平衡晶状体一样,可以像2D中的平衡晶状体一样。但是,即使在存在此类领域的情况下,当对称性断裂场很弱时,主动元素在噪声方面仍然比噪声稳定要小得多。
We show that dislocations in active 2d smectics with underlying rotational symmetry are always unbound in the presence of noise, meaning the active smectic phase does not exist for non-zero noise in $d=2$. The active smectic phase can, like equilibrium smectics in 2d, be stabilized by applying rotational symmetry breaking fields; however, even in the presence of such fields, active smectics are still much less stable against noise than equilibrium ones, when the symmetry breaking field(s) are weak.
