De Broglie wavelength shift in gravitational fields

Main Question or Discussion Point

Photons are blue-shifted as they accelerate in free-fall toward the earth. When an electron or positron is conceptualized as a wave using de Broglie's equation, are the de Broglie wavelengths of the electron or positron shortened (blue-shifted) as they accelerate toward the earth in free-fall? In other words do gravitational fields effect the quantum de broglie representation of matter-waves?

Atyy didn't quite say so explicitly, but the answer to the OP's question is yes.

Thanks for the reference. I am reading it now and finding it fascinating. It will take time for me to absorb it.

Thanks for the quick answer. I have wondered about this for some time.
