Towards X-Ray Ramsey Interferometry using Nuclear Resonant Scattering — •Lukas Wolff and Jörg Evers — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Nonlinear spectroscopic techniques such as multidimensional spectroscopy or pump-probe spectroscopy have become indispensable tools for probing ultrafast dynamics of quantum systems in the optical and infrared regime. In contrast, precise control of timing and phase properties of light pulses in the X-ray and XUV-regime still remains challenging due to the properties of available coherent X-ray sources and optics. In the hard X-ray regime, Mößbauer nuclei featuring exceptionally narrow resonances can be employed to split light from modern high-brilliance coherent x-ray sources into double-pulses with characteristic spectral features. High-precision control of the relative phase between these double-pulses was demonstrated recently using fast mechanical motion of nuclear targets.

Here, we explore the possibility of using X-ray double-pulses created with Mößbauer nuclei to implement Ramsey interferometry in the low-excitation regime of nuclear resonant scattering. Our findings may help to pave the way towards multi-pulse control and probe schemes in the hard X-ray regime.
