Diffusion NMR in periodic media: efficient computation and spectral properties
Nicolas Moutal, Antoine Moutal, Denis S. Grebenkov
The Bloch-Torrey equation governs the evolution of the transverse magnetization in diffusion magnetic resonance imaging, where two mechanisms are at play: diffusion of spins (Lapla…

Diffusion across semi-permeable barriers: spectral properties, efficient computation, and applications
Nicolas Moutal, Denis Grebenkov
We present an efficient method to compute the eigenvalues and eigenmodes of the diffusion operator on one-dimensional heterogeneous structures with multiple semi-…
