X- ray quantum and nonlinear optics

Sharon Shwartz research group

We study nonlinear optics and quantum optic effects in the x-ray regime.
This includes for example

 X-ray sum-frequency generation.

 X-ray parametric down-conversion.

 Generation and manipulation of non-classical light.

 Developing new spectroscopy and microscopy techniques based on the quantum nature of light.

We are recruiting graduate students and post-docs.

We study novel nonlinear and quantum effects at x-ray wavelengths.

Our research projects include theoretical and experimental studies aimed at the discovery of fundamental effects as well as the development of new imaging and spectroscopy techniques.

We preform our experiments in our x-ray diffractometer  and also at synchrotron and x ray free electron laser facilities all over the world.
