We show that dynamical synthetic gauge fields may be engineered using periodically modulated interactions. We discuss two scenarios in one-dimensional lattices where periodic interactions may realize a quantum Peierls phase. We discuss how this dynamical gauge field may be probed in stroboscopic measurements of the momentum distribution in time-of-flight experiments. These measurements will show a density-dependent shift of the momentum distribution, revealing as well the quantum character of the created Peierls phase.
