Transitions as the Native Objects of Dispersive Light-Matter Dynamics
Mohamed Meguebel, Maxime Federico, Louis Garbe +2
The paper presents a framework that treats light‑matter transitions as the primary dynamical objects, providing a compact diagrammatic method for multiphoton processes and enabling…
Effective Hamiltonians in Cavity and Waveguide QED from Transition-Operator Diagrammatic Perturbation Theory
Mohamed Meguebel, Maxime Federico, Louis Garbe +2
We propose an adiabatic-elimination formalism in the dispersive regime based on a transition-centric perturbation theory. The perturbative expansion is recast into a diagrammatic f…
Excitable quantum systems: the bosonic avalanche laser
Louis Garbe, Peter Rabl
We investigate the dynamics of a lasing system driven by a current of bosonic (quasi-)particles via a dissipative three-mode mixing process. A semi-classical analysis of this syste…
Refrigeration of a 1D gas of microwave photons
Lukas SchamriÃ, Lukas Schamriß, Louis Garbe +1
We discuss a conceptually simple scheme for cooling a one dimensional gas of microwave photons in a superconducting transmission line. By shunting one end of the transmission line…
