Theory Advances in High-Precision Two-Photon Spectroscopy
High-precision two-photon spectroscopy of hydrogen and hydrogenlike systems constitutes an exceptional tool for experimental tests of fundamental theories. In the analysis of these experiments, theory also plays a vital role in the modeling of time-resolved spectra, the calculation of precise …

Spectroscopic Study of Ultracold Rubidium Atoms in an Optical Dipole Force Trap
… atoms confined in the trap, we have performed spectroscopy on the 5<em>S</em><sub>1/2</sub> → 5<em>P</em><sub>3/2</sub> transition. Because the polarizability of the ground and excited states is not the same at the trap wavelength, the spectra exhibit both a shift and inhomogeneous broadening. …

Defects and charge-carrier lifetime in early-stage photovoltaic materials : relating experiment to theory
… materials predicted to be "defect tolerant." Two-photon spectroscopy is then employed to decrease the effect of surface recombination, enabling more representative estimates of "bulk" lifetime. Second, the role of impurities is explored by intentionally contaminating lead halide perovskites with …

3 GHz Yb-fiber laser based femtosecond sources and frequency comb
… arbitrary waveform generation, high-speed photonic analog-to-digital conversion, and high-resolution spectroscopy. Femtosecond optical sources in the wavelength range between 0.7 [mu]m and 1.55 [mu]m have found many applications such as optical coherence tomography, high speed optical …

Multiphoton correlations and emitters
… stages. A deterministic or on-demand single-photon source and, more recently, an N-photon emitter, seem to play a crucial role. Nevertheless, even the correct characterisation of the former is still a source of discussion and there exist several criteria to do so. The identification of the …

Ultrafast Raman Scattering in Plasmonic Nanocavities
… coherence, and the generation of correlated photon pairs. In plasmonic nanocavities, optical fields are enhanced 100-fold and focused to a nanometre-thin gap. Vibrations of molecules placed in the cavity interact strongly with the optical resonances, forming a coupled optomechanical system. …

Use of nanoemulsion liquid chromatography (NELC) for the analysis of inhaled drugs. Investigation into the application of oil-in-water nanoemulsion as mobile phase for determination of inhaled drugs in dosage forms and in clinical samples.
There has been very little research into the bioanalytical application of Microemulsion High Performance Liquid Chromatography (MELC), a recently established technique for separating an active pharmaceutical ingredient from its related substances and for determining the quantity of active drug in a …
