Effective Faraday interaction between light and nuclear spins of Helium-3 in its ground state: a semiclassical study

Matteo Fadel, Philipp Treutlein, Alice Sinatra

We derive the semiclassical evolution equations for a system consisting of helium-3 atoms in the $2^{3}S$ metastable state interacting with a light field far-detuned from the $2^3S-2…
