Time-dependent spectra of quantum beats
Héctor M. Castro-Beltrán, Ricardo Román-Ancheyta
We obtain time-resolved spectra of spontaneous emission and resonance fluorescence of a single multilevel emitter where two antiparallel transitions interfere and cause quantum bea…
Spectroscopy and critical quantum thermometry in the ultrastrong coupling regime
M. Salado-Mejía, R. Román-Ancheyta, F. Soto-Eguibar +1
We present an exact analytical solution of the anisotropic Hopfield model, and we use it to investigate in detail the spectral and thermometric response of two ultrastrongly couple…
Collectively enhanced thermalization via multiqubit collisions
Angsar Manatuly, Wolfgang Niedenzu, Ricardo Román-Ancheyta +3
We investigate the evolution of a target qubit caused by its multiple random collisions with -qubit clusters. Depending on the cluster state, the evolution of the target qubit m…
Time-dependent spectra of a three-level atom in the presence of electron shelving
Ricardo Roman-Ancheyta, Octavio de los Santos Sanchez, Levente Horvath +1
We investigate time-dependent spectra of the intermittent resonance fluorescence of a single, laser-driven, three-level atom due to electron shelving. After a quasi-stationary stat…
Phase-dependent fluctuations in intermittent resonance fluorescence
Hector M. Castro-Beltran, Ricardo Roman-Ancheyta, Luis Gutierrez
Electron shelving gives rise to bright and dark periods in the resonance fluorescence of a three-level atom. The corresponding incoherent spectrum contains a very narrow inelastic…
