论文摘要
通过工程涂层实现强烈的令人反感的卡西米尔力量可以为微型和纳米机电应用铺平道路，在这些应用中，粘合力目前会引起可靠性问题。在这里，我们利用Lifshitz理论来确定在陀螺仪介质中对两种限制案例（Ultra-Strong Gyroelectric and non-Gyroelectric）的反击Casimir力的要求。我们表明，具有强度强烈的陀螺症（例如Weyl半金属）的培养基中排斥力的起源是由真空波动极化的巨大相互转换引起的。
Achieving strong repulsive Casimir forces through engineered coatings can pave the way for micro- and nano-electromechanical applications where adhesive forces currently cause reliability issues. Here, we exploit Lifshitz theory to identify the requirements for repulsive Casimir forces in gyrotropic media for two limiting cases (ultra-strong gyroelectric and non-gyroelectric). We show that the origin of repulsive force in media with strong gyrotropy such as Weyl semi-metals arises from the giant interconversion of polarization of vacuum fluctuations.
