Dynamics of a Spin-Exchange Relaxation-Free Comagnetometer for Rotation Sensing

Jiali Liu et al.

Summary: This study investigates the dynamics of the spin-exchange relaxation-free (SERF) comagnetometer for rotation sensing. Transient and steady-state models of the rotation response are established using a set of Bloch equations. The measuring range of the comagnetometer is explored through experiments and simulations, and methods to improve the measuring range are proposed.

Atomic Spin Polarization Controllability Analysis: A Novel Controllability Determination Method for Spin-Exchange Relaxation-Free Co-Magnetometers

Zhuo Wang et al.

Summary: This paper investigates the controllability of atomic spin polarization in SERFCMs. The Bloch equations are used to describe the dynamic behavior of spin polarization in atomic spin ensemble systems. A state-space model is established for the atomic spin polarization in SERFCM, which belongs to a class of nonlinear systems. A novel determination method for global state controllability is proposed and implemented in the analysis of the atomic spin polarization. A theoretically feasible control input solution is proposed under physical constraints to achieve more practical and accurate controller design. The simulation results validate the proposed controllability determination method.
