Ultracold Fermions: Laughlin States and Lattice Algorithms
Speaker:Philipp Preiss (Max Planck Institute of Quantum Optics)
Abstract:Understanding systems of many interacting fermionic is one of the most important and conceptually challenging problems in quantum science. Ultracold neutral Fermi gases, allow us to probe such systems with microscopic control over all degrees of freedom. I will report on experiments that explore the few-particle limit of the quantum Hall effect. We emulate strong magnetic fields using rapidly rotating microtraps and find that two particles can be driven into a ½ Laughlin state. These results pave the way for the exploration of fractional quantum Hall physics with ultracold fermions. More widely, ultracold atoms may emulate other Fermi systems, such as those in quantum chemistry or lattice gauge theories. We have developed a novel scheme to realize universal fermionic wavefunctions and measure arbitrary correlation functions using tunnelling and interaction gates. I will discuss the plan
