纳米通道中激发态原子的分子放大
Enlarged Molecules from Excited Atoms in Nanochannels
摘要：
探讨了平面纳米通道中激发态原子对之间的共振相互作用。我们认为在二氧化硅，氧化锌和金的通道中的相互作用。纳米尺寸的通道诱导一个显着不同的相互作用，从自由空间。对两个锂和铯原子的计算表明，存在一个短程排斥，然后是长程吸引。表面附近的结合能最强。放大分子的尺寸在腔中心最大，并随通道宽度的增加而增大。由于相互作用是通用的，我们预测，扩大的分子形成的多孔结构，和分子的大小取决于纳米通道的大小
英文摘要：
The resonance interaction that takes place in planar nanochannels between pairs of excited state atoms is explored. We consider interactions in channels of silica, zinc oxide and gold. The nanosized channels induce a dramatically different interaction from that in free space. Illustrative calculations for two lithium and cesium atoms, demonstrate that there is a short range repulsion followed by long range attraction. The binding energy is strongest near the surfaces. The size of the enlarged molecule is biggest at the center of the cavity and increases with channel width. Since the interaction is generic, we predict that enlarged molecules are formed in porous structures, and that the molecule size depends on the size of the nanochannels
