超振荡使不寻常的跃迁成为可能
Unusual Transitions Made Possible by Superoscillations
摘要:
我们提出了一个物理方案,其中一个电磁场的状态组成的光子的能量小于两态粒子的能隙,与粒子相互作用,为任意长的持续时间,就好像它是由光子的能量匹配的粒子的能隙。这种类型的相互作用是可能的,当场是在一个特别定制的状态,其磁场的期望值是一个超振荡函数。
英文摘要:
We present a physical scenario in which an electromagnetic field in a state consisted of photons whose energies are smaller than the energy gap of a two-state particle, interacts with the particle, for an arbitrarily long duration, as if it was consisted of photons whose energy matches the energy gap of the particle. This type of interaction is possible when the field is in a specially tailored state whose magnetic field's expectation value is a superoscillatory function.
