Ground-state chiral current via periodic modulation
Ground-state chiral current via periodic modulation
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 …
