- Abstract summary: We perform a combined theoretical and experimental investigation of the superradiance in the quantum coherent system generated by strong laser fields.
The semiclassical theory of superradiance that includes the superradiant temporal profile, character duration, time delay, intensity is derived.
Our results not only demonstrate that the time-delayed optical amplification inside the molecular nitrogen ions is superradiance, but also reveal the quantum optical properties of strong-field physics.

- Abstract: We perform a combined theoretical and experimental investigation of the
superradiance in the quantum coherent system generated by strong laser fields.
The semiclassical theory of superradiance that includes the superradiant
temporal profile, character duration, time delay, intensity is derived. The
experimental data and theoretical predictions of 391-nm forward emission as a
function of nitrogen gas pressure are compared and show good agreement. Our
results not only demonstrate that the time-delayed optical amplification inside
the molecular nitrogen ions is superradiance, but also reveal the quantum
optical properties of strong-field physics.

Recent theories have laid the groundwork for understanding how quantum-optical properties affect high-field photonics.
We demonstrate a new experimental approach that transduces some properties of a quantum-optical state through a strong-field nonlinearity.
Our results suggest that perturbing strong-field dynamics with quantum-optical states is a viable way to coherently control the generation of these states at short wavelengths.

Superradiant Raman scattering of Rubidium atoms has been explored in the experiment [Nature 484, 78 (2012).
We develop a quantum master equation theory by treating the Rubidium atoms as three-level systems, and coupling them with a dressed laser and an optical cavity.
Our studies provide a unified view on the superradiant Raman scattering pulses, and an alternative explanation to the broad spectrum of the steady-state Raman scattering.

Recent theoretical predictions hint at an implementation of a superradiant laser based on narrow optical clock transitions.
We show that the temperature threshold can be significantly increased by using more atoms.
Interestingly we see that higher order atom-field and direct atom-atom quantum correlations play only a minor role in the laser dynamics.

All optical materials with a positive refractive index have a value of index that is of order unity.
Despite the giant response of an isolated atom, we find that the maximum index does not indefinitely grow with increasing density.
We propose an explanation based upon strong-disorder renormalization group theory.

We show that environmental radioactive materials and cosmic rays contribute to an elevated quasiparticle density that would limit superconducting qubits of the type measured here to coherence times in the millisecond regime.
Introducing radiation shielding reduces the flux of ionizing radiation and positively correlates with increased coherence time.
