非线性(非谐)Casimir振子

Nonlinear (Anharmonic) Casimir Oscillator

Habibollah Razmi, Mohammad Reza Mohammadi, Mahnaz Abdollahi, Seyed Mahdi Fazeli

摘要:

我们想研究一个简单的线性谐振微弹簧的动力学,它是在量子Casimir力/压力的影响下,因此表现为一个(一个)非线性(非谐)Casimir振荡器。这种非线性微机械Casimir振子的运动方程一般没有精确解(解析)解且系统的转折点没有固定位置;然而,对于微型弹簧的刚度的特定值以及在适当地精心选择的距离尺度和条件下,对于该问题存在近似正弦的解(在非常小的位置间隔中收集可变的转折点)。这是一种简单而初步的方案,对微机械器件中的Casimir静摩擦问题的控制可能是有用的。

英文摘要:

We want to study the dynamics of a simple linear harmonic micro spring which is under the influence of the quantum Casimir force/pressure and thus behaves as a (an) nonlinear (anharmonic) Casimir oscillator. Generally,the equation of motion of this nonlinear micromechanical Casimir oscillator has no exact solvable (analytical)solution and the turning point(s) of the system has (have) no fixed position(s); however, for particular values of the stiffness of the micro spring and at appropriately well-chosen distance scales and conditions, there is (are) approximately sinusoidal solution(s) for the problem (the variable turning points are collected in a very small interval of positions). This, as a simple and elementary plan, may be useful in controlling the Casimir stiction problem in micromechanical devices.
