Dynamical resonance florescence (RF) in cavity-QED and waveguide-QED

We discuss the long sought after regime of “dynamical resonance florescence,” which adds significant modification and control to the usual CW resonance florescence schemes such as the Mollow triplet, when using excitation pulses whose time duration is shorter than the inverse decay time of the quantum emitter. We present several examples, including (i) semiconductor quantum dot cavity systems, where we will show recent experiments and simulations side by side, and (ii) waveguide QED systems excited with few photon Fock state pulses. Using state of the art quantum simulation algorithms, including tensor networks, we describe how the usual emission spectrum and intensity outputs are dynamically modified with short pulse excitation, and demonstrate how even single photon population effects are uniquely accessed in this regime. These short-pulsed emission regimes allow for the generation of a variety of exotic quantum states of light.
