Electric-dipole spin resonance

Electric gates can control spin through spin–orbit or gradient coupling.

01 / Mathematical framework
$$H_d(t)=\hbar\Omega\cos(\omega t)\sigma_x$$

Physical intuition

Electric gates can control spin through spin–orbit or gradient coupling.

Deep dive: physical mechanism

An oscillating electric field moves the electron and generates an effective transverse spin drive.

What is measured experimentally?

Drive-frequency maps show electric-field-controlled Rabi oscillations.

Assumptions, noise and limitations

Micromagnet gradients and spin–orbit mechanisms are platform dependent.

Research and simulation exercise

Compare Rabi rate against electric-field amplitude.
