编者按:新冠肺炎疫情冲击了全球学校教育系统。为有效应对此次危机,OECD发布系列报告《热点聚焦:形塑教育的趋势》(Spotlights - Trends Shaping Education)。其中,文章《新冠肺炎疫情特别关注:重返校园》(Coronavirus Special Edition: Back to School)从两个维度提出了应对规划:重返校园的短期规划和此后18~24个月恢复教育系
A pure fourfold-azimuthal dependence of terahertz radiation from polished mono-crystalline Si (100) is observed.This phenomenon is explained by the second-o
We investigate the generation mechanism of high harmonics from the bulk of a ZnO crystal driven by intense mid-IR laser pulses by perturbing it with a weak
Recently Terahertz (THz) radiation from laser-produced plasmas has attracted much interest since plasmas can work at arbitrarily high laser intensity.This paper
in this work, we model the transient absorption of attosecond pulses of laser-dressed atoms by considering a three-level system.We study the delay-dependent
Using classical ensemble model, we investigate the sensitivity of double ionization in circularly polarized laser fields to the initial ensembles that are g
Attosecond electron bunches can be applied in several fields such as in electron microscopy with temporal resolution of attosecond, generating x-ray pulse o
