 The seminar will present a Raman study of ZrAs2 single crystals, a nodal line semimetal. We identified the symmetry of phonon modes by polarized light measurements and comparison with calculated phonon frequencies. Significant dependence of peak intensities on the excitation wavelength indicates quantum interference effects. The electronic background, with quasi-elastic scattering is observed. The temperature dependence of phonon peaks linewidth indicates that the electron-phonon coupling plays an essential role in phonon decay. Preliminary results of the high pressure Raman measurements of ZrAs2 will be presented.

The seminar will be given in Polish on-site in room 203, slides will be in English. ZOOM transmission will be available too.
