# Bernhard W. Adams

Bernhard Adams received his diploma in x-ray interferometery from the University of Munich. Following his Ph.D. at the University of Munich on the influence of a surface on phase-transition kinetics, he completed post-doctoral work at DESY in Hamburg, studying atom-resolving x-ray holography and parametric down conversion of x rays. He is currently a staff scientist at Argonne National Laboratory, where his main scientific interests include ultrafast (picosecond) x-ray spectroscopy and x-ray quantum optics, such as x-ray parametric down conversion, nuclear $γ$-ray superradiance, and the Casimir force.

## Geometric phase kicks x rays down a new path

Published June 14, 2010
A small crystal distortion can dramatically translate the path of an x-ray beam, an effect that could be useful in the development of x-ray optics.
