Chip-scale atomic magnetometer based on free-induction-decay
… cell with nitrogen buffer gas, operating in a free-induction-decay configuration. This allows us to monitor the free Larmor precession of the spin coherent Cs atoms by separating the pump and probe phases in the time domain. A single light pulse can sufficiently polarise the atomic …

The development and applications of Fourier transformed relaxation measurements in nuclear magnetic resonance (NMR)
… spectrum. By Fourier transforming the free induction decay after the inversion recovery or spin echo pulse sequences, the different frequency components can be resolved and their individual relaxation times can be measured. This method has great advantages over the conventional method …

Implementation of anatomical navigators for real time motion correction in diffusion tensor imaging
… prospective acquisition correction, or a free induction decay navigator have recently been applied to correct for motion in diffusion tensor imaging. These methods have some limitations and drawbacks. This article describes a novel technique using a three-dimensional-echo planar imaging …

Exploring large coherent spin systems with solid state NMR
… investigation of the problem of the NM:R free induction decay (FID) in a lattice of spin 1/2 nuclei is presented to verify the multi-spin nature of the FID and the dominant role of the geometrical arrangement of the spins in the development of higher order correlations under the dipolar …

Particle microstructure and polymer dynamics in concentrated polymer solutions
… is linked to the polymer dynamics using free induction decay of NMR experiments, which directly quantify the amount of polymer adsorption while multi-quantum NMR experiments probe the existence of physical crosslinks and entanglements. Taken together this thesis provides detailed …

Direct observation of Rydberg-Rydberg transitions via CPmmW spectroscopy
… (20 GHz bandwidth), high-resolution (50 kHz), free induction decay-detected (FID) spectroscopy with accurate relative intensities (10%), which is successfully applied to record Rydberg-Rydberg spectra of Calcium and Barium atoms. To extend CPmmW spectroscopy to a molecular system, I have …

Nuclear spin coherence times of HD trapped in solid parahydrogen matrices
… and detection. Using this platform, we carry out free-induction decay spectroscopy, multi-Lorentzian lineshape analysis, spin-echo measurements, and longitudinal relaxation studies on parahydrogen samples doped with HD molecules. Across a range of sample conditions, we observe an improvement on …

Chirped-pulse millimeter-wave spectroscopy, dynamics, and manipulation of Rydberg-Rydberg Transitions
… region, the excited transitions re-radiate free induction decay (FID) at their resonant frequencies, and the FID is heterodyne-detected by the CPmmW spectrometer. Data collection and averaging are performed in the time domain. The spectral resolution is ~100 kHz. Because of the large …

A tale of two interfaces: photons and spins linked by a solid-state artificial atom
… of an electron spin, and probe its coherence via free induction decay and Hahn-echo spectroscopy. The scientific insights and technical knowledge gained from this work could enable the construction of a quantum dot system consisting of a qubit (an electron spin) and a high-fidelity, in situ …

Slow and fast light by spectral hole-burning in the solid state
… coherent transients such as Rabi oscillations, free-induction decay and self-induced transparency (SIT). Switching between slow and fast light was obtained by transient hole-burning, which was reported for the first time. These results could pave the way to applications such as all optical …

Order phenomena in polymer crystallization
… been used. The MSE allows the measurement of the free induction decay (fid) without signal loss from fast decaying signal of immobile chain segments during the so called dead time. The decay of the slowly decaying amorphous regions was measured via the CPMG sequence. Three different fractions of …
