已经观察到直径为 14 至 17 nm 的金颗粒因相干准备的声振动模式而产生的量子拍。拍频与颗粒尺寸成反比。移相时间约为。 15 ps,受到样品尺寸分布广泛(+/-2 nm)的限制。 (C) 1998 年美国物理研究所。 [S0021-9606(98)70222-3]。
Quantum beats due to coherently prepared acoustic vibrational modes have been observed for 14 to 17 nm diameter Au particles. The beat frequency is inversely proportional to the particle size. The dephasing time is ca. 15 ps, which is limited by the broad size distribution (+/-2 nm) of the samples. (C) 1998 American Institute of Physics. [S0021-9606(98)70222-3].
