• Abstract: In this study, we engineer the Dzyaloshinskii-Moriya interaction mediated by photons to emulate ground-state chiral current based on three-level atoms driven by quantum and classical fields. We employ adiabatic elimination techniques to derive an effective Dzyaloshinskii-Moriya interaction Hamiltonian of two-level systems, which can address the challenges arising from the finite lifetime of excited states. Furthermore, we can ensure to achieve desired dynamics through the implementation of periodic modulation on the atomic ground states. Besides, three-state and multi-state chiral current can be obtained by choosing appropriate driving frequencies and phases. We also design the Dzyaloshinskii-Moriya interaction for the other components based on a toggling frame. The numerical simulation results further indicate that our proposal can generate a perfectly reliable ground-state chiral current and open up possibilities for quantum state transfer and the development of future quantum networks.

We develop a collisional model to implement reservoir engineering for the one-dimensional harmonic motion of a trapped ion. Having multiple internal levels, we show that multiple reservoirs can be engineered, allowing for more efficient synthesis of well-known non-classical states of motion.
