Master 2 (2022-2023)
Study of Rabi oscillations using optically detected NMR in polarised helium gas
Pulses of resonant ac fields are generically used to control the internal state of 2-level systems. The driven travel on the Bloch sphere is a standard (but approximate!) textbook item. Optical monitoring of actual trajectories will provide new insight on recent NMR investigations of deviations due to (often unavoidable) additional components of the oscillating field. Download a 1-page description of the project. Please contact us for more information.
