We show that the saturation of a multiphoton transition is accompanied by a gradual collapse of quantum multimodality in the strong-coupling limit of the weakly driven Jaynes-Cummings (JC) model. By means of a perturbative method, we illustrate the prominent role of quantum fluctuations by focusing on the two and three-photon resonance operation in a regime where the steady-state average photon number is below or marginally above unity. We also reveal two coexistent quantum beats in the…

Coherent generation of non-classical light on a chip via photon-induced tunnelling and blockade

Quantum dots in photonic crystals are interesting because of their potential in quantum information processing and as a testbed for cavity quantum electrodynamics. Recent advances in controlling and

Quantum theory of optical bistability. I. Nonlinear polarisability model

A quantum treatment of a coherently driven dispersive cavity is given based on a cubic nonlinearity in the polarisability of the internal medium. This system displays bistability and hysteresis in

Spontaneous dressed-state polarization of a coupled atom and cavity mode

The authors calculate the asymptotic quantum state of a driven cavity mode interacting with a two-state atom when the dipole coupling constant is much larger than the atomic and cavity linewidths.

Nonlinear response of the vacuum Rabi resonance

The exploration of the Jaynes–Cummings Hamiltonian in a circuit-QED system—where an ‘artificial atom’ made of a superconducting circuit is strongly coupled to a microwave field—provides direct

Wigner function for a driven anharmonic oscillator

We consider the quantum model of a driven anharmonic oscillator, in the presence of dissipation, and present an exact analytic solution for the corresponding Wigner function in the steady-state

Photon blockade in an optical cavity with one trapped atom

TLDR
Observations of photon blockade for the light transmitted by an optical cavity containing one trapped atom, in the regime of strong atom–cavity coupling represent an advance over traditional nonlinear optics and laser physics, into a regime with dynamical processes involving atoms and photons taken one-by-one.

Single atom optical bistability

Absorptive optical bistability is shown to exist for a single two-level atom inside a resonant optical cavity. Solutions for the quantum-mechanical density operator are obtained numerically for a
