Competition between Zeeman and hyperfine pumping in thermal atomic vapor

Competition between Zeeman and hyperfine pumping in thermal atomic vapor

We present ab initio reduced rate equation models to study the interplay of Zeeman and hyperfine pumping, which determines the Doppler-broadened absorption spectra of an arbitrarily polarized probe laser, in thermal atomic vapor. Our simple models (with maximum seven levels) accurately predict the d...
