论文摘要
我们通过蒙特卡洛模拟研究了加压球形壳的屈曲，其中详细的平衡被明确损坏了 - 从而使壳驱动壳，从而使壳脱离热平衡。这样的壳通常具有较高（活动性）或较低（静止）的波动，而在热平衡中的波动取决于详细的平衡的破损方式。我们表明，对于相同的一组弹性参数，如果转动活跃，则不扣在热平衡中的壳可以扣紧。同样，如果静止，则在热平衡中弯曲的外壳会解开。基于此结果，我们建议可以通过实验设计微观的弹性壳可以通过光学控制。
We study the buckling of pressurized spherical shells by Monte Carlo simulations in which the detailed balance is explicitly broken -- thereby driving the shell active, out of thermal equilibrium. Such a shell typically has either higher (active) or lower (quiescent) fluctuations compared to one in thermal equilibrium depending on how the detailed balance is broken. We show that for the same set of elastic parameters, a shell that is not buckled in thermal equilibrium can be buckled if turned active. Similarly, a shell that is buckled in thermal equilibrium can unbuckle if turned quiescent. Based on this result, we suggest that it is possible to experimentally design microscopic elastic shells whose buckling can be optically controlled.
