Abstract Metallic nanoclusters and aromatic molecules are nano systems which display pair correlation similar to that in usual superconductors. Metallic clusters contain delocalized electrons whose states form energy shells similar to those in atoms or nuclei. Under special but perfectly realistic conditions, superconducting pairing in metallic nanoclusters is very strong. For realistic sets of parameters one can expect a high value of T c ( 150 K); in principle, it is possible to raise T c up to room temperature. Electrons in aromatic molecules form a two-dimensional finite Fermi system and also can display phenomena caused by pair correlation.

纳米系统中的对相关性

摘要 金属纳米团簇和芳香族分子是纳米系统，其表现出与普通超导体相似的配对关系。金属簇包含离域电子，其状态形成类似于原子或原子核中的能量壳。在特殊但完美现实的条件下，金属纳米团簇中的超导配对非常强。对于现实的参数集，可以期待 T c (150 K) 的高值；原则上，可以将T c 升高到室温。芳香分子中的电子形成二维有限费米系统，也可以显示由对相关引起的现象。
