Dynamics of position-phase probability density in magnetic resonance
Cem Yolcu, Magnus Herberthson, Carl-Fredrik Westin +1
We consider the behaviour of precessional angle (phase) carried by molecules of a diffusing specimen under magnetic fields typical of magnetic resonance experiments. An evolution e…

Orientationally-averaged diffusion-attenuated magnetic resonance signal for locally-anisotropic diffusion
Magnus Herberthson, Cem Yolcu, Hans Knutsson +2
Diffusion-attenuated MR signal for heterogeneous media has been represented as a sum of signals from anisotropic Gaussian sub-domains. Any effect of macroscopic (global or ensemble…

NMR signal for particles diffusing under potentials: From path integrals and numerical methods to a new model of diffusion anisotropy
Cem Yolcu, Muhammet Memiç, Kadir Şimşek +2
We study the influence of diffusion on NMR experiments when the molecules undergo random motion under the influence of a force field, and place special emphasis on parabolic (Hooke…
