论文摘要
使用极化张量的形式主义，研究了纳米颗粒和在不同温度下保持在不同温度下的石墨烯片之间的非平衡Casimir-polder力。结果表明，力量随着石墨烯片的温度升高而增加。在较大的分离下，非平衡条件对力的影响变小。根据我们的结果，有吸引力的Casimir-Polder力在某些确定的纳米颗粒 - 透明烯分离下消失，如果石墨烯片的温度小于环境的温度，则在较大的分离下会消除。这种效果可能会在石墨烯的基本研究和对生物电子制剂微型试验中的控制中的基本研究中的应用。
The nonequilibrium Casimir-Polder force between a nanoparticle and a graphene sheet kept at different temperatures is investigated in the framework of Dirac model using the formalism of the polarization tensor. It is shown that the force magnitude increases with increasing temperature of a graphene sheet. At larger separations an impact of nonequilibrium conditions on the force becomes smaller. According to our results, the attractive Casimir-Polder force vanishes at some definite nanoparticle-graphene separation and becomes repulsive at larger separations if the temperature of a graphene sheet is smaller than that of the environment. This effect may find applications both in fundamental investigations of graphene and for the control of forces in microdevices of bioelectronics.
