论文摘要
我们概括了Dalibard，Dupont-Roc和Cohen-Tannoudji（DDC形式主义）提出的形式主义，这是第四顺序与两个原子相互作用，与真空中的标量场相互作用，在有限温度$ t $上进行热浴，然后计算出在两次地面且在两次地面上分离出的偏见的反应，并分别构成的分离，并分离出偏见的范围。详细介绍了范德华和卡西米尔 - 票相互作用的热校正。我们发现了一个特定区域，即$ \ sqrt [4] {λ^3β} \ ll ll l \ l \llλ$，带有$ l $，$β$和$β$和$λ$，表示原子间分离，热光子的波长，热光子的波长，以及普通的范围，这是在范围内的范围，这是在范围内，这是一个普遍的范围。随着温度升高，原子间相互作用的有趣的跨界现象。我们还发现，当温度足够高时，热校正会对Casimir-Polder力发生重大变化，从而在$λ\llβ\ ll l $区域中与$ tl^{ - 3} $成比例的吸引力，并且可以在$β\ llll $ ll $ ll $ ll ll $ action中具有有吸引力的或拒绝的力量。
We generalize the formalism proposed by Dalibard, Dupont-Roc, and Cohen-Tannoudji [the DDC formalism] in the fourth order for two atoms in interaction with scalar fields in vacuum to a thermal bath at finite temperature $T$, and then calculate the interatomic interaction energy of two ground-state atoms separately in terms of the contributions of thermal fluctuations and the radiation reaction of the atoms and analyze in detail the thermal corrections to the van der Waals and Casimir-Polder interactions. We discover a particular region, i.e., $\sqrt[4]{λ^3β}\ll L\ll λ$ with $L$, $β$ and $λ$ denoting the interatomic separation, the wavelength of thermal photons and the transition wavelength of the atoms respectively, where the thermal corrections remarkably render the van der Waals force, which is usually attractive, repulsive, leading to an interesting crossover phenomenon of the interatomic interaction from attractive to repulsive as the temperature increases. We also find that the thermal corrections cause significant changes to the Casimir-Polder force when the temperature is sufficiently high, resulting in an attractive force proportional to $TL^{-3}$ in the $λ\llβ\ll L$ region, and a force which can be either attractive or repulsive and even vanishing in the $ β\llλ\ll L$ region depending on the interatomic separation.
