Mathematics, 2021 It has been increasingly reported that in biological tissues diffusion-weighted MRI signal attenuation deviates from mono-exponential decay, especially at high b-values.

Electrical detection of spin echoes for phosphorus donors in silicon [PDF]
, 2007 The electrical detection of spin echoes via echo tomography is used to observe decoherence processes associated with the electrical readout of the spin state of phosphorus donor electrons in silicon near a SiO$_2$ interface.

Simultaneous spin‐echo refocusing [PDF]
Magnetic Resonance in Medicine, 2005 AbstractA new approach to spin‐echo imaging is presented in which the 180° RF pulse refocuses two or more spin‐echoes at different positions in the readout period. When simultaneous echo refocusing (SER) is implemented using multiple 180° pulses, an undesirable mixing of stimulated echoes and primary echoes from different slices can occur.

Parallel and anti-parallel echoes in beam spin echo experiments
Results in Physics, 2019 The refocusing of velocity-dependent spin-phase is the basic phenomenon behind helium and neutron spin echo beam experiments. In this paper we present quantum and classical descriptions of the spin echo phenomenon and show that non-adiabatic transitions,

Physical Review A, 2018 We show that quantum coherence produces an observable many-body signature in the dynamics of few-fermion Hubbard systems (describing cold atoms in optical lattices, coupled quantum dots, or small molecules) in the form of a revival in the transition probabilities echoing a flip of the system's itinerant spins.

Semi-classical model for the dephasing of a two-electron spin qubit coupled to a coherently evolving nuclear spin bath [PDF]
, 2011 We study electron spin decoherence in a two-electron double quantum dot due to the hyperfine interaction, under spin-echo conditions as studied in recent experiments.
