We demonstrate the practical spin selectivity of the force by pushing or pulling a specific spin state while leaving other spin states unmoved.ĭetermination of serum aluminum by electrothermal atomic absorption spectrometry: A comparison between Zeeman and continuum background correction systemsĮxcessive exposure to aluminum (Al) can produce serious health consequences in people with impaired renal function, especially those undergoing hemodialysis. We observe that the dressed- atom eigenstates gradually mix over time and have mapped out this behavior as a function of magnetic field and detuning. Our measurements are consistent with a simple two-level theory for the ac Zeeman effect and demonstrate its resonant, bipolar, and spin-dependent nature. An atom chip produces a microwave near field with a strong amplitude gradient, and we observe a force over three times the strength of gravity. We measure the ac Zeeman force on an ultracold gas of 87Rb due to a microwave magnetic field targeted to the 6.8 GHz hyperfine splitting of these atoms.
