Brenden, Wen-Te, and Adriana of MPIK in Heidelberg have released a new paper investigating collective effects that could occur in Thorium doped crystals when excited by narrow-band coherent pulses. Here’s the link to the paper. A variety of schemes are discussed with the goal of creating unique signatures of excitation which can be used to determine the detuning of the exciting laser pulses from 229Th nuclear transition energy. Other details such as multi pulsed excitation, pulse shape, phase shifting, static magnetic fields and quantization axis are discussed to give a comprehensive understanding of the possibilities when tackling such a project.

A personal note from the nuClock coordinator: This work fulfills the last formal deliverable for EU reporting, rejoice!
