Studying quantum physics with a Sr quantum gas microscope
Understanding many-body quantum systems can be very hard. Even simplified models of important solid state systems, such as high-temperature superconductors, cannot be solved on the most powerful classical computers. The reason is that these computers work after classical laws and the quantum mechanical Hilbert space, in which quantum systems are described, easily overwhelms their capacity. To obtain insights into complicated quantum systems all the same, we can artificially create quantum systems that implement the models that we want to investigate. By using well-controlled ultracold quantum gases to engineer quantum systems, we can investigate the quantum phases of those systems and their reactions to parameter changes.
We will use strontium quantum gases to explore quantum physics. Strontiumís long-lived optically excited states, ultra-narrow optical transitions and large nuclear spin are very useful for the creation of artificial gauge fields and spin-orbit coupling, which are important ingredients in interesting condensed matter models. We are currently constructing a new apparatus, which will have the capability to manipulate and detect Sr lattice gases at the single-site, single-atom level.
