The momentum increase is so substantial, that it surpasses that of free-space photons by a factor of a thousand, making it comparable to the electron momenta in materials." ...

However, they do have energy and momentum. The energy of a photon is given by Planck's constant times the frequency of the light, and the momentum of a photon is given by Planck's constant times ...

Photons carry energy and also momentum-- that momentum is what atomic physicists use to cool atoms with lasers-- and both of those things get transferred to the electron when it absorbs a photon.

The development of color routers (CRs) realizes modulation of photon momentum on the frequency and spatial domains. Scientists in China demonstrate an active manipulation of dichromatic photon ...

When the photon momentum and the atomic velocity are at an angle larger than 90 degrees, the atom and the light are counterpropagating and the Doppler shift is an upward shift in frequency.
