论文摘要
我们根据光子诱导的近场电子显微镜（Pinem）中离散的能量边带（PINEM）提出了超快免费电子的合成维度。 Pinem合成维度可以提供一种强大的方法，可以在超快传输电子显微镜，介电激光加速器和量子自由电子激光器等系统中相干地塑造或调节自由电子波函数。作为此范式的示例，我们证明了Bloch振荡，衍射管理和线性光学效应，例如Pinem晶格中的Talbot自象。这些效果表明了Pinem合成维度作为新型量子模拟平台的潜力。
We propose a synthetic dimension for ultrafast free electrons based on the discrete energy sidebands in photon-induced near-field electron microscopy (PINEM). The PINEM synthetic dimension can offer a powerful way to coherently shape or modulate free-electron wavefunctions in systems such as ultrafast transmission electron microscopes, dielectric laser accelerators, and quantum free-electron lasers. As examples of this paradigm, we demonstrate Bloch oscillations, diffraction management, and linear optics effects such as Talbot self-imaging in the PINEM lattice. These effects show the potential of PINEM synthetic dimensions as a novel quantum simulation platform.
