Plasmon–Exciton Polariton (2D): Time-Domain Rabi Beating & Anticrossing

2D canvas model of plasmon-exciton strong coupling: a real-time RK4 integration of the temporal coupled-mode equations shows Rabi energy beating and decay between a plasmon and an exciton oscillator, alongside the analytic anticrossing diagram of the same non-Hermitian Hamiltonian.

This is a 2D-native companion to the 3D plasmon–exciton polariton simulator, built around the exact same non-Hermitian coupled-oscillator Hamiltonian but visualized without any 3D geometry. One panel sweeps the analytic anticrossing diagram — the upper and lower polariton energies plotted against detuning — while the other numerically time-integrates the equivalent Schrödinger-like coupled-mode equations with a 4th-order Runge–Kutta solver, so you watch a real quantum-beat energy exchange between the plasmon and exciton oscillators rather than a static formula. Tune the coupling strength, detuning and linewidths and see both the frequency-domain and time-domain pictures of strong coupling update together, live.

⚙ Under the hood

2D canvas companion to the plasmon-exciton strong-coupling simulator: a real-time 4th-order Runge-Kutta integration of the temporal coupled-mode equations shows literal Rabi energy beating and decay between a plasmon oscillator and an exciton oscillator, side by side with the analytic anticrossing diagram of the same non-Hermitian 2x2 Hamiltonian.
