The theory group of A. Pálffy (Heidelberg) proposed a new mechanism to connect between optical photons and X-rays. This interface is an optical resonator, where one of the cavity mirrors is formed by a micro-mechanical cantilever. The tip of the cantilever contains specific nuclei of interest (e.g. 229Th), which resonantly absorb X-rays in a Mössbauer-type fashion. The preprint is entitled “An Optomechanical Interface Bridging X-Ray and Optical Photons” and can be found here: arXiv:1508.06769.
The official kick-off meeting of our nuClock project is currently taking place in Munich! For two days (September 14/15), some 30 experts will discuss recent results and future experiments related to the hunt for the isomer transition. The nuClock members are joined by a number of external scientists, coming from as far as the US and China, to make nuClock the central hub of Thorium research. We are looking forward to a fruitful meeting in an enthusiastic atmosphere. After all, it’s Oktoberfest season in Munich!
