活塞上的卡西米尔力

Casimir force on a piston

R. M. Cavalcanti

摘要:

考虑二维L × b矩形盒壁上的无质量标量场,该盒被可移动隔板(活塞)分成尺寸为a × b和(L-a)× b的两个腔室.我们计算在极限L ->无穷大时作用在活塞上的Casimir力。无论a/b的值如何,活塞都被吸引到盒子的最近端。对于a &lt; &gt; b,导出了作用在活塞上的Casimir力的渐近表达式< b and a >.

英文摘要:

We consider a massless scalar field obeying Dirichlet boundary conditions on the walls of a two-dimensional L x b rectangular box, divided by a movable partition (piston) into two compartments of dimensions a x b and (L-a) x b. We compute the Casimir force on the piston in the limit L -> infinity. Regardless of the value of a/b, the piston is attracted to the nearest end of the box. Asymptotic expressions for the Casimir force on the piston are derived for a << b and a >> b.
