Area of Science:

• Physics
• Chemistry
• Biophysics

Background:

• Simulating magnetic resonance experiments with coupled spatial and quantum dynamics is challenging.
• Existing methods like Bloch-Torrey and Liouville-von Neumann formalisms have limitations in handling complex spin Hamiltonians and spatial motion simultaneously.

Purpose of the Study:

• To develop and implement an advanced simulation framework for spatio-temporal magnetic resonance experiments.
• To overcome the limitations of existing methods in simulating experiments where spatial dynamics coexist with quantum spin dynamics.

Main Methods:

• Formulation and implementation of a simulation framework based on the Fokker-Planck equation.
• Integration of spatial dynamics (diffusion, flow) with quantum spin dynamics (spin-spin couplings, exchange, cross-relaxation) and chemical kinetics.

Main Results:

• The proposed framework enables simulation of complex spatio-temporal magnetic resonance experiments without significant approximations.
• Successfully simulates scenarios where spatial motion is intimately coupled with quantum spin dynamics, relaxation, and chemical kinetics.

Conclusions:

• The Fokker-Planck based framework provides a powerful and versatile tool for simulating advanced magnetic resonance experiments.
• This advancement opens new possibilities for understanding and designing complex magnetic resonance studies in various scientific fields.
