Coherent interactions of relativistic free electron wavepackets with strong optical fields is a interaction research. In my talk I will explore a new regime of electron-light interactions where the electrons are comparatively slow (~20-200eV).  First, we show that sub-optical-cycle electron bursts induced by tunneling photoemission from a metal nanotip can retain the temporal fingerprint of their emission dynamics [1]. In the second part, we consider a phase-matched interac cornerstone of recent light-mattertion between a slow electron and a strong optical field. We find a strong tunable confinement of the electron spectrum, a new fundamental effect only accessible for slow electrons [2]. An appropriate choice of light field parameters can reduce the interaction dynamics to only two energy states. These combined capabilities expand the scope of electron beam physics, free-electron quantum optics and quantum simulators.
