- Abstract: The generation of nonclassical light states bears a paramount importance in
quantum optics and is largely relying on the interaction between intense laser
pulses and nonlinear media. Recently, electron beams, such as those used in
ultrafast electron microscopy to retrieve information from a specimen, have
been proposed as a tool to manipulate both bright and dark confined optical
excitations, inducing semiclassical states of light that range from coherent to
thermal mixtures. Here, we show that the ponderomotive contribution to the
electron-cavity interaction, which we argue to be significant for low-energy
electrons subject to strongly confined near-fields, can actually create a more
general set of optical states, including coherent and squeezed states. The
post-interaction electron spectrum further reveals signatures of the nontrivial
role played by $A^2$ terms in the light-matter coupling Hamiltonian,
particularly when the cavity is previously excited by either chaotic or
coherent illumination. Our work introduces a disruptive approach to the
creation of nontrivial quantum cavity states for quantum information and optics
applications, while it suggests unexplored possibilities for electron beam
shaping.
