Peter Sun-mrfmsim: a modular simulation platform for magnetic resonance force microscopy experiments

MRFMSIM is a modular simulation platform developed for magnetic resonance force microscopy (MRFM) experiments, designed to be lightweight and flexible

The platform enables high-resolution 3D imaging of individual biomolecules and protein assemblies, potentially achieving sub-engineering resolution

Key features include:

• Post-definition modification capabilities
• Plugin system for extending functionality
• YAML configuration files for improved readability
• Rich metadata support
• Graph-based representation of processes
• Easy parameter looping and optimization

The simulation accurately models spin behavior under magnetic fields, including:

• Spin flips when applying transverse fields
• Resonance conditions at specific frequencies
• Cantilever frequency changes during spin detection

Built with graduate students and experimental researchers in mind:

• Focus on code readability and maintainability
• Easy testing and debugging
• Simple sharing with collaborators
• Reduced error propagation
• Memory optimization features

Supports multiple experimental protocols and setups:

• Different resonator types (cantilevers, membrane resonators)
• Various magnet geometries and materials
• Multiple sample configurations

Designed to handle:

• 3D data structures
• Grid-based calculations
• Parallel computing capabilities
• HDF5 file format for intermediate values
