Universal spectral bounds for the quantum Rabi model: Reformulating Braak's conjecture
Alfonso Lanuza
The quantum Rabi model is a paradigmatic example of a minimal yet nontrivial light-matter interaction, whose spectrum is transcendental yet exhibits a number of regularities. Braak…

Exact solution for the collective non-Markovian decay of two fully excited quantum emitters
Alfonso Lanuza, Dominik Schneble
Waveguide quantum electrodynamics constitutes a modern paradigm for the interaction of light and matter, in which strong coupling, bath structure, and propagation delays can break…

Super- and subradiant dynamics of quantum emitters mediated by atomic matter waves
Youngshin Kim, Alfonso Lanuza, Dominik Schneble
The cooperative modification of spontaneous radiative decay is a paradigmatic many-emitter effect in quantum optics. So far its experimental realization has involved interactions m…
