Emulating Solid-State Physics with a Hybrid System of Ultracold Ions and Atoms — •Ulf Bissbort1,2,3, Daniel Cocks3, Antonio Negretti4, Zbigniew Idziaszek5, Tommaso Calarco6, Ferdinand Schmidt-Kaler7, Walter Hofstetter3, and René Gerritsma71MIT, Cambridge, USA — 2SUTD, Singapore — 3Johann Wolfgang Goethe-Universität, Frankfurt/Main, Germany — 4Zentrum für Optische Quantentechnologien, Hamburg, Germany — 5Faculty of Physics, University of Warsaw, Poland — 6Institut für Quanteninformationsverarbeitung, Universität Ulm, Germany — 7Institut für Physik, Johannes Gutenberg-Universität Mainz, Germany

We propose and theoretically investigate a hybrid system composed of a crystal of trapped ions coupled to a cloud of ultracold fermions. The ions form a periodic lattice and induce a band structure in the atoms. This system combines the advantages of high *delity operations and detection offered by trapped ion systems with ultracold atomic systems. It also features close analogies to natural solid-state systems, as the atomic degrees of freedom couple to phonons of the ion lattice, thereby emulating a solid-state system. Starting from the microscopic many-body Hamiltonian, we derive the low energy Hamiltonian, including the atomic band structure, and give an expression for the atom-phonon coupling. We discuss possible experimental implementations such as a Peierls-like transition into a period-doubled dimerized state.
