Following on my previous blog post on Exciting with quantum light, I want to give some updates of the results we've been gathering these last months at the occasion of the publication of our first two opuses, or, as Phys. Rev. typesetters prefer to call them, the first two parts:
(note that they also changed the title from "Exciting with Quantum Light" to "Excitation with Quantum Light", but it's still "exciting" when it comes to what we excite).
Part I remains essentially that I already blogged about previously so I do not need to add much, mainly remind us that this is defining the problem—exciting a target with the self-consistent dynamical output of a quantum emitter—and considering the simplest case where the target is merely an harmonic oscillator. The formalism itself, going beyond Hamiltonian dynamics by allowing irreversibility, was put forward simultaneous by Gardiner[1] and Carmichael[2] (!?) and we used that to show which states of the harmonic oscillator's Hilbert space you can drive your target into.
