IMPRS-APS: Realizing Feynman’s Dream of a Quantum Simulator (Prof. Immanuel Bloch)

This has become possible by using complex experimental setups of thousands of optical elements, which allow atoms to be cooled to Nanokelvin temperatures, where they almost come to rest. The atoms can then be trapped and manipulated in arrays of millions of microscopic light traps. Such light crystals allow an unprecedented view into the microscopic world of quantum materials and enable the currently most precise atomic clocks, fundamental to next-generation timing and navigation. In this public lecture, I will explain how such quantum simulators are realized at the lowest temperatures known, and highlight their applications, which range from condensed-matter physics and statistical physics to ‘table-top’ high-energy physics.
