Quantum Biomimetic Modeling of Diamond NV⁻ Center Spin Dynamics

The spin dynamics of the diamond NV$^{-}$ center turns out to be similar to that of the chemical compass responsible for avian magnetoreception. We present a simulation framework based on quantum master equation for the former that is based upon the Radical Pair model of the latter. We show that this framework captures all the experimentally studied behavior of the NV$^{-}$ center spin system and can therefore be a predictive modeling tool.
