Floquet-Induced Superfluidity with Periodically Modulated Interactions of Two-Species Hardcore Bosons in a One-dimensional Optical LatticeTao Wang1, Shijie Hu2, Sebastian Eggert2, Michael Fleischhauer2, •Axel Pelster2, and Xue-Feng Zhang31Hubei Key Laboratory of Optical Information and Pattern Recognition, Wuhan Institute of Technology, China — 2Physics Department and Research Center OPTIMAS, Technische Universität Kaiserslautern, Germany — 3Department of Physics, Chongqing University, China

We consider two species of hard-core bosons with density dependent hopping in a one-dimensional optical lattice, for which we propose experimental realizations using time-periodic driving. The quantum phase diagram for half-integer filling is determined by combining different advanced numerical simulations with analytic calculations. We find that a reduction of the density-dependent hopping induces a Mott-insulator to superfluid transition. For negative hopping a previously unknown state is found, where one species induces a gauge phase of the other species, which leads to a superfluid phase of gauge-paired particles. The corresponding experimental signatures are discussed.
