- Abstract: We demonstrate that spin-dependent electron diffraction is possible for a
smooth range of transverse electron momenta in a two-photon Bragg scattering
scenario of the Kapitza-Dirac effect. Our analysis is rendered possible by
introducing a generalized specification for quantifying spin-dependent
diffraction, yielding an optimization problem which is solved by making use of
a Newton gradient iteration scheme. With this procedure, we investigate the
spin-dependent effect for different transverse electron momenta and different
laser polarizations of the standing light wave Kapitza-Dirac scattering. The
possibility for using arbitrarily low transverse electron momenta, when setting
up a spin-dependent Kapitza-Dirac experiment allows longer interaction times of
the electron with the laser and therefore enables less constraining parameters
for an implementation of the effect.

Here, we show that control over electron pulse shaping, compression, and statistics can be improved by replacing coherent laser excitation by interaction with quantum light.
We find that compression is accelerated for fixed optical intensity by using phase-squeezed light, while amplitude squeezing produces ultrashort double-pulse profiles.
The generated electron pulses exhibit periodic revivals in complete analogy to the optical Talbot effect.
