We theoretically investigate a scheme for generations of single hard X-ray pulses of controllable duration in the range of 1 ns -100 ns from a radioactive Mössbauer source. The scheme uses a magnetically perturbed 57 FeBO3 crystal illuminated with recoilless 14.4 keV photons from a radioisotope 57 Co nuclide. Such compact X-ray source is useful for the extension of quantum optics to 10 keV energy scale which has been spotlighted in recent years. So far, experimental achievements are mostly performed in synchrotron radiation facilities. However, tabletop and portable hard X-ray sources are still limited for time-resolved measurements and for implementing coherent controls over nuclear quantum optics systems. The availability of compact hard Xray sources may become the engine to apply schemes of quantum information down to the subatomic scale. We demonstrate that the present method is versatile and provides an economic solution utilizing a Mössbauer source to perform time-resolved nuclear scattering, to produce suitable pulses for photon storage and to flexibly generate X-ray single-photon entanglement.

Coherent Control of Nuclei and X-Rays

The possibility of mutual control of nuclei and photons offered by the emerging field of nuclear quantum optics is theoretically investigated in three different applications. This extension of quantum optics towards nuclei is motivated by modern X-ray Free Electron Lasers (XFEL) which open the possibility to coherently control nuclear states. As a first application we investigate the coherent population transfer between nuclear states in a three-level system driven by an XFEL. Such a level scheme is relevant for the triggering of isomers and might play a role for future energy storage solutions. The other way around, nuclei offer a platform to control single x-ray photons, which can be focused on spots essentially smaller than a single atom and used in future photonic circuits. The second part of this thesis puts forward a nuclear forward scattering setup that allows coherent control of a single x-ray photon using 57 Fe nuclei. Finally, we show that nuclear quantum optics provides a significant improvement for detection in nuclear physics. The low-lying isomeric transition of 229 Th can be addressed by VUV lasers and provides a potential next generation frequency standard. A main impediment is the large uncertainty of the nuclear transition frequency. Using an electromagnetically modified nuclear forward scattering setup, we show that coherence effects can reduce this uncertainty down to an unprecedented level.Within the framework of this thesis, the following articles were published in refereed journals:

Mößbauer Spectroscopy

Mössbauer spectroscopy and related synchrotron radiation‐based nuclear resonance techniques are powerful albeit specialized methods that provide unique insights into the dynamics and coordination of atoms by probing transitions between a nuclear excited state and a nuclear ground state. This chapter provides examples that bear a relation to solid‐state chemistry of how Mössbauer spectroscopy has contributed to our understanding of the structure and properties of materials. A most informative quantity that can be obtained from a Mössbauer spectroscopy experiment is the isomer shift δ. Empirically, this quantity is obtained from the center of mass of a particular component or subspectrum. Whereas the isomer shift provides a localized measure of the electronic density at the nucleus ‐ a Coulomb‐type charge monopole interaction ‐ the quadrupole splitting of the nuclear levels measures the distortion of the spatial distribution of the electronic charge around the nucleus.

Scientific legacy of Stanley Ruby

Abstract: Stanley L. Ruby made major contributions to Mössbauer spectroscopy and was the first to suggest the feasibility of observing the Mössbauer effect using synchrotron radiation. In this article we recall his scientific legacy that have inspired his scientific colleagues.
