标题： Quantum dissipative effects in moving imperfect mirrors: sidewise and normal motions

摘要： 我们扩展了之前关于动态卡西米尔效应功能方法的工作，以计算由于两个平坦、平行、不完美的镜子在真空中相对运动引起的耗散效应。 镜子内部自由度与真空场之间的相互作用通过真空场作用量中的非局部项进行建模。 我们考虑两种不同的情况：一种是运动为“正常”情况，即镜子前进或后退，改变它们之间的距离$a(t)$；另一种是“平行”情况，即$a$保持不变，但镜子平面之间存在相对滑动运动。 对于后者，我们明确展示了即使在恒定位移速度下也存在非零的摩擦力。 显示英文摘要

摘要： We extend our previous work on the functional approach to the dynamical Casimir effect, to compute dissipative effects due to the relative motion of two flat, parallel, imperfect mirrors in vacuum. The interaction between the internal degrees of freedom of the mirrors and the vacuum field is modeled with a nonlocal term in the vacuum field action. We consider two different situations: either the motion is `normal', i.e., the mirrors advance or recede changing the distance $a(t)$ between them; or it is `parallel', namely, $a$ remains constant, but there is a relative sliding motion of the mirrors' planes. For the latter, we show explicitly that there is a non-vanishing frictional force, even for a constant shifting speed.
