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

本课题研究原子尺度时空约束下，即皮米长度和阿秒时间尺度下的电子输运统计。在这种情况下，基本过程和现象，如基本电荷和电磁场的真空波动之间的强库仑相关，预计将发挥重要作用。该实验是通过近红外稳定的单周期光和带电读出的等离子体微结构相结合而实现的。将样品冷却至2 K以下是为了避免结构不稳定，并能够使用微波单电子晶体管技术对电荷波动进行单次测量。

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.
