Efficient simulation of ultrafast magnetic resonance experiments

Efficient simulation of ultrafast magnetic resonance experiments
Efficient simulation of ultrafast magnetic resonance experiments
Magnetic resonance spectroscopy and imaging experiments in which spatial dynamics (diffusion and flow) closely coexists with chemical and quantum dynamics (spin-spin couplings, exchange, cross-relaxation, etc.) have historically been very hard to simulate – Bloch-Torrey equations do not support complicated spin Hamiltonians, and the Liouville - von Neumann formalism does not support explicit spatial dynamics. In this communication, we formulate and implement a more advanced simulation framework based on the Fokker-Planck equation. The proposed methods can simulate, without significant approximations, any spatio-temporal magnetic resonance experiment, even in situations when spatial motion co-exists intimately with quantum spin dynamics, relaxation and chemical kinetics.

Abstract

Magnetic resonance spectroscopy and imaging experiments in which spatial dynamics (diffusion and flow) closely coexists with chemical and quantum dynamics (spin-spin couplings, exchange, cross-relaxation, etc.) have historically been very hard to simulate – Bloch-Torrey equations do not support complicated spin Hamiltonians, and the Liouville - von Neumann formalism does not support explicit spatial dynamics. In this communication, we formulate and implement a more advanced simulation framework based on the Fokker-Planck equation. The proposed methods can simulate, without significant approximations, any spatio-temporal magnetic resonance experiment, even in situations when spatial motion co-exists intimately with quantum spin dynamics, relaxation and chemical kinetics.
