Double Quantum Dot Avoided-Crossing & Tunneling Resonance

This simulator renders the same physics behind a gate-defined double quantum dot's charge-stability honeycomb, but as a 2D avoided-crossing (energy-level) diagram cut through a single interdot transition instead of a 3D height map of the whole gate-voltage plane. As detuning ε is swept across the transition, the two diabatic charge-state energies cross linearly while interdot tunnel coupling t_c hybridizes them into bonding/antibonding levels separated by a minimum gap 2t_c — the microscopic origin of the honeycomb's rounded triple points. A synchronized Lorentzian current trace and a live left/right localization readout, both derived from the identical two-level Hamiltonian and tunneling-current formula, complete the picture. Tune t_c, the charging energies and thermal broadening Γ, then follow the sweeping probe.
