Electrically Driven Vacuum Rabi Oscillations as a Potential Quantum-Optical Device

The dynamics of a charge bounded by a chain of coupled artificial atoms, interacting simultaneously with a single mode quantized electromagnetic field inside a cavity, and a constant electrostatic DC field is presented in this work. We develop an extended Jaynes-Cummings model describing this system and solve it both analytically and numerically, with good agreement between the two methods. It is shown that the charge-photon dressed state is modulated with the Bloch frequency due to the interaction with the DC field. This enables to control the quantum state of light by adiabatically changing the DC field. This novel effect might be important for the application of optical modulators, quantum computing and electrically controlled quantum antennas.
