Broad-band spectroscopy of a vanadyl porphyrin: a model electronuclear spin qudit
I. Gimeno, A. Urtizberea, J. Román-Roche +5
We explore how to encode more than a qubit in vanadyl porphyrin molecules hosting a electronic spin 1/2 coupled to a nuclear spin 7/2. The spin Hamiltonian and its parameters, as w…

Photon Condensation and Enhanced Magnetism in Cavity QED
Juan Román-Roche, Fernando Luis, David Zueco
A system of magnetic molecules coupled to microwave cavities ( resonators) undergoes the equilibrium superradiant phase transition. The transition is experimentally observable.…

Bound states in ultrastrong waveguide QED
Juan Román-Roche, Eduardo Sánchez-Burillo, David Zueco
We discuss the properties of bound states in finite-bandwidth waveguide QED beyond the Rotating Wave Approximation or excitation number conserving light-matter coupling models. The…
