Enlarged molecules from excited atoms in nanochannels

Bostrom, Mathias; Brevik, Iver; Sernelius, B; Dou, Maofeng; Persson, Clas; Ninham, Barry


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...[Show more]
