Ultracold Strontium

In April 2015, we started a new lab with the aim of studying many-body quantum physics with ultracold strontium atoms in optical lattices. Our lab is located at the Max-Planck-Institute for Quantum Optics in Garching, Germany, in Immanuel Bloch’s Quantum Many-Body Physics Division.

Within the last ten years, we have witnessed an exciting interaction between precision measurement and many-body physics because the world’s most accurate and precise clocks — operating at the 2 × 10-18 level — are based on fermionic 87Sr trapped in optical lattices. Doing measurements with 18 digits of precision required understanding the interactions between the strontium atoms at an unprecedented level.


We believe that the strontium atom offers many more exciting possibilities to improve our understanding of many-body quantum physics. We are working towards
