Here we show that the recent experimentally realized shaken optical lattice provides a pathway to realize FFLO superfluids and MFs. By tuning the shaking frequency and amplitude, various couplings between the s and p orbitals of the lattice (called the pseudospins) can be generated. We show that the combination of the s- and p-band dispersion inversion, the engineered pseudospin coupling, and the on-site attractive interaction naturally allows the observation of FFLO superfluids as well as MFs in different parameter regions.en©2015 American Physical Society.Quantum phase transitionSuperconductorsFermionsSuperfluidityOpticsOptical latticesArticleZheng, Zhen, Chunlei Qu, Xubo Zou, and Chuanwei Zhang. 2015.
