Experiments on nonlinear spin oscillations in a rarefied quantum gas; spin polarized atomic hydrogen

Abstract

Spin transport in a polarized quantum gas can be described by a set of highly nonlinear local equations of motion1 which can be linearized to yield an equation that resembles a Schroedinger equation with damping or a dissipative Heisenberg ferromagnet. To date2 pulsed magnetic resonance experiments on such systems have been restricted to the linear response. We present the results of studies on spin polarized atomic hydrogen in the fully nonlinear regime and, in particular, on the evolution of the pulsed magnetic resonance frequency spectrum which results as the system is disturbed increasingly far from equilibrium.
