WebOur model opened a new way for the optimization of quantum memories in alkali-matal atoms and in other systems subject to hyperfine splitting. This work has led to a succesful experimental demonstration of EIT enhancement in a Cs vapor [Scherman, Mishina et al., Opt. Expr. 20, 4346, (2012)], an important step towards the realization of an efficient … Web27 mrt. 1998 · S. Brattke, U. Kallmann, W.-D. Hartmann The coherent dark resonance between the hyperfine levels F=1, m=0 and F=2, m=0 of the rubidium ground state has been observed experimentally with the light of a pulsed mode-locked diode laser operating at the D1 transition frequency.

The hyperfine states of a trapped ion are commonly used for storing qubits in ion-trap quantum computing. They have the advantage of having very long lifetimes, experimentally exceeding ~10 minutes (compared to ~1 s for metastable electronic levels). Meer weergeven In atomic physics, hyperfine structure is defined by small shifts in otherwise degenerate energy levels and the resulting splittings in those energy levels of atoms, molecules, and ions, due to electromagnetic … Meer weergeven The theory of hyperfine structure comes directly from electromagnetism, consisting of the interaction of the nuclear multipole moments (excluding the electric monopole) with internally generated fields. The theory is derived first for the atomic case, but can be applied … Meer weergeven Astrophysics As the hyperfine splitting is very small, the transition frequencies are usually not located in the optical, but are in the range of radio- or microwave (also called sub-millimeter) frequencies. Hyperfine … Meer weergeven The first theory of atomic hyperfine structure was given in 1930 by Enrico Fermi for an atom containing a single valence electron with an arbitrary angular momentum. … Meer weergeven Hyperfine interactions can be measured, among other ways, in atomic and molecular spectra and in electron paramagnetic resonance spectra of free radicals and transition-metal ions.
