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…

Transitions as the Native Objects of Dispersive Light-Matter Dynamics
Mohamed Meguebel, Maxime Federico, Louis Garbe +2
We introduce a framework where light-matter transitions, rather than states, are the primary dynamical objects. Successive compositions of elementary transitions yield multiphoton…

Generation of frequency entanglement with an effective quantum dot-waveguide two-photon quadratic interaction
Mohamed Meguebel, Maxime Federico, Simone Felicetti +2
Light-matter interactions with quantum dots have been extensively studied to harness key quantum properties of photons, such as indistinguishability and entanglement. In this theor…
