WebJan 26, 2016 · We demonstrate coherent population trapping of a single nuclear spin in a room-temperature solid. To this end, we exploit a three-level system with a Λ configuration in the microwave domain, which consists of nuclear spin states addressed through their hyperfine coupling to the electron spin of a single nitrogen-vacancy defect in diamond. WebOct 29, 2024 · This coherent trapping of the spin polarization is analogous to the mechanism of coherent population trapping (19, 20) in the sense that, in both cases, the system can be understood as a set of coupled oscillators that become effectively decoupled from one of their degrees of freedom (i.e., the optical transitions).

"WebWe demonstrate very high-contrast coherent population trapping1 (CPT) resonances by using four-wave mixing in 87Rb atoms. In the experiment, we take advantage of the spectral overlap between F=2→F and F=3→F optical resonances on the D1 line of 87Rb and 85Rb atoms, respectively, to eliminate the DC-light background from the CPT resonance signal.
