Theoretical analysis reveals a microscopic origin of static friction at solid interfaces, demonstrating how interlocking electron orbits convert electrostatic repulsion into slip resistance.

Key Points

To identify the microscopic physical origin of static friction by evaluating atomic-scale interactions and electron orbital distributions at contacting solid interfaces.
Modeled the spatial topography and disordered distribution of elliptical electron orbits across solid interfaces under gravity and external pressure.
Analyzed the geometric interlocking of adjacent orbital trajectories and the resulting conversion of electrostatic repulsion into lateral slip resistance.
Stationary solid interfaces naturally form stable coincident structures where interleaved elliptical electron orbits lock together under normal pressure.
Lateral motion requires overcoming significant transverse electrostatic repulsion between locked orbits, which rapidly decays once macroscopic sliding initiates and disrupts the coincident structure.
