Coulomb correlations and non-Poissonian statistics in attosecond picotransport (A01)

本项目研究原子尺度时空约束下的电子输运统计，即皮秒长度和阿秒时间尺度下的电子输运。在这种情况下，基本的过程和现象，如基元电荷和电磁场的真空涨落之间的强库仑关联，有望发挥重要作用。这些实验是通过相稳定的单周期近红外光和带有电子读数的等离子体微微结构的组合来实现的。将样品冷却到2K以下是为了避免结构不稳定性，并使用微波单电子晶体管技术实现对电荷波动的逐个测量。

This project studies the statistics of electron transport under atomic-scale spatio-temporal confinement, i.e. at picometer length and attosecond time scales. In this regime, fundamental processes and phenomena such as strong Coulomb correlations between elementary charges and vacuum fluctuations of the electromagnetic field are expected to play a significant role. The experiments are enabled by a combination of phase-stable single cycles of light in the near infrared and plasmonic picostructures with electrical readout. Cooling of the samples below 2 K is intended to avoid structural instabilities and to enable shot-to-shot measurements of charge fluctuations with microwave single-electron transistor technology.
