“左手”球附近激发态原子的超衰变
A Superdecay of an excited atom placed near ''Left-Handed'' sphere
摘要：
同时具有负介电常数和磁导率的微球（左手球）上的允许和禁止的跃迁的衰减速率的影响被认为是。它被发现，与通常的（右手）材料相比，即使在小半径的球体的情况下，也有可能增加几个数量级的衰变率。这种增强是由于存在一种新型的共振模式（LH表面模式）。得到了新模态的谐振频率和相关品质因数的解析表达式。
英文摘要：
The influence of a microsphere having a simultaneously negative permittivity and permeability (Left-Handed Sphere) on the decay rate of the allowed and forbidden transitions is considered. It is found, that in contrast to usual (Right-Handed) materials it is possible to increase the decay rate by several orders of magnitude even in the case of a sphere of small radii. This enhancement is due to the fact that there exist a new type of resonance modes (LH surface modes). The analytical expressions for resonance frequencies and associated quality factors of the new modes are found.
