Unitary p-wave interactions between fermions in an optical lattice
Exchange-antisymmetric pair wavefunctions in fermionic systems can give rise to unconventional superconductors and superfluids. The realization of these states in controllable quantum systems, such as ultracold gases, could enable new types of quantum simulations, topological quantum gates and exotic few-body states. However, p-wave and other antisymmetric interactions are weak in naturally occurring systems, and their enhancement via Feshbach resonances in ultracold systems has been limited by three-body loss.
