The authors measure voltage-dependent exciton lifetimes in a quantum dot molecule and show that phonon-assisted relaxation resonances and anti-resonances explain the non-monotonic decay rates.
A 5 ps laser pulse is applied to excite the crystal ground state (|vac⟩) to the p-orbital of the neutral exciton (p-shell excita- tion)

Resonant and Anti-resonant Exciton-Phonon Coupling in Quantum Dot Molecules
The authors measure voltage-dependent exciton lifetimes in a quantum dot molecule and show that phonon-assisted relaxation resonances and anti-resonances explain the non-monotonic decay rates.
