3 p, 288.9 KB Saturation spectroscopy in optically thick three-level gas media / Schmidt Iglesias, Carola (Universitat Autònoma de Barcelona. Departament de Física) ; Roso Franco, Luis (Universitat Autònoma de Barcelona. Departament de Física) ; Corbalán, R. (Ramón) (Universitat Autònoma de Barcelona. Departament de Física)
High-contrast transmission spectra arising from saturated absorption in optically thick Doppler-broadened three-level media are analyzed within the formalism of Maxwell-Bloch-type equations. It is found that although in the strong pumping engine propagation-induced line narrowing and light-shift elimination occur, spectral features lying within the natural linewidth cannot be resolved.

Institut für Angewandte Physik, Technische) ; Mompart Penina, Jordi (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
We investigate arrays of three traps with two fermionic or bosonic atoms. The tunneling interaction between neighboring sites is used to prepare multisite dark states for the empty site (i. e. , the hole) which allows for the coherent manipulation of its external degrees of freedom. [...]

7 p, 824.8 KB Dipole spectrum structure of nonresonant nonpertubative driven two-level atoms / Picón Álvarez, Antonio (Universitat Autònoma de Barcelona.

Departament de Física) ; Plaja, L. (Universidad de Salamanca. Departamento de Física Aplicada) ; American Physical Society
We analyze the dipole spectrum of a two-level atom excited by a nonresonant intense monochromatic field under the electric dipole approximation and beyond the rotating wave approximation. We show that the apparently complex spectral structure can be completely described by two families: harmonic frequencies of the driving field and field-induced nonlinear fluorescence. [...]

4 p, 94.5 KB Coherent population trapping in two-electron three-level systems with aligned spins / Mompart Penina, Jordi (Universitat Autònoma de Barcelona. Departament de Física) ; Corbalán, R. (Ramón) (Universitat Autònoma de Barcelona. Departament de Física) ; Roso, Luis (Universidad de Salamanca. Departamento de Física Aplicada) ; American Physical Society
The possibility of coherent population trapping in two electron states with aligned spins (orthosystem) is evidenced. From the analysis of a three-level atomic system containing two electrons, and driven by the two laser fields needed for coherent population trapping, a conceptually new kind of dark state appears. [...]
