Engineering interactions shape in resonantly driven bosonic gas

In systems with fast periodic driving, there are special subsets of (resonant) states, which behavior can be described with effective, time-independent Hamiltonian in a rotating reference frame. Here, we show that experimentally feasible system of ultracold bosonic atoms on a ring with rapidly oscillating scattering length can be used to simulate time-independent two-component atomic mixture with exotic, long-range interactions. --- Source: arXiv:2602.15582v1 - http://arxiv.org/abs/2602.15582v1 ...
