Abstract
We calculate the time evolution of a cavity-QED system subject to a time dependent
sinusoidal drive. The drive is modulated by an envelope function with the shape of a
pulse. The system consists of electrons embedded in a semiconductor nanostructure which is
coupled to a single mode quantized electromagnetic field. The electron-electron as well as
photon-electron interaction is treated exactly using “exact numerical diagonalization” and
the time evolution is calculated by numerically…

This work uses a quantum-well waveguide structure to optically tune light–matter interaction from weak to ultrastrong and turn on maximum coupling within less than one cycle of light, and directly monitors how a coherent photon population converts to cavity polaritons during abrupt switching.
