Engineering interactions shape in resonantly driven bosonic gas

Damian Włodzyński, Krzysztof Sacha·Feb 17, 2026

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 ul...
