Probing fundamental constant evolution with astronomical spectroscopy

Probing polar molecules with high harmonic spectroscopy.

We bring the methodology of orienting polar molecules together with the phase sensitivity of high harmonic spectroscopy to experimentally compare the phase difference of attosecond bursts of radiation emitted upon electron recollision from different ends of a polar molecule. This phase difference has an impact on harmonics from aligned polar molecules, suppressing emission from the molecules pa...

Probing nanoscale ferroelectricity by ultraviolet Raman spectroscopy.

We demonstrated that ultraviolet Raman spectroscopy is an effective technique to measure the transition temperature (Tc) in ferroelectric ultrathin films and superlattices. We showed that one-unit-cell-thick BaTiO3 layers in BaTiO3/SrTiO3 superlattices are not only ferroelectric (with Tc as high as 250 kelvin) but also polarize the quantum paraelectric SrTiO3 layers adjacent to them. Tc was tun...

Probing protein conformation by infrared spectroscopy.

Infrared Spectroscopy has become a usual technique in studies of protein conformation. The use of modern instruments based on interferometric devices together with the application of Fourier-transform techniques makes possible to obtain high signal-to-noise ratio spectra. These advantages allow to apply resolution enhancement techniques such as deconvolution or derivation in order to derive inf...
