Old model, new fun - quantum simulation of Hubbard models
The Hubbard Model in all its variations plays a central role in the description of strongly correlatedmany-body systems. Despite its simple form, the solution of the model remains a challenge for analytical andnumerical methods. Quantum simulation has been established as an alternative solution method in the last 20years. My talk takes a comprehensive look at this development and introduces both atomic and electronic many-body systems suitable for quantum simulation of Hubbard models. In particular, the focus is on variousextensions of the model, such as electron-phonon interaction, long-range interactions, two-layer geometry, whichplay an important role for superconductivity or superfluidity, as well as for exotic phases with broken latticesymmetries.
