Two distinct charge density waves in the quasi-one-dimensional metal Sr0.95NbO3.37 (Sr- and O-deficient n = 5) revealed by resonant soft X-ray scattering
A comprehensive study revealed the presence of two distinct and simultaneous charge density waves (CDWs). Remarkably, they appear not along the metallic a-axis but along the non-metallic c-axis and one is a Peierls-like CDW and the other is a Wigner crystal CDW.

Optical and photoinduced properties of the quasi-1D metals Sr0.95NbO3.37 (Sr- and O-deficient n = 5) and SrNbO3.45 (n = 4.5)
A comprehensive study revealed particular photoinduced features. Among others, a special laser-based mid-infrared (MIR) pump-probe reflectance setup was build. It allows room temperature transient pump-probe reflectivity experiments with fully controlled anisotropic polarizations on the sample.

Excitonic quenching of the oxygen-chain phonon in the photoinduced metal-to-insulator transition of photoexcited Sr0.95NbO3.37 (Sr- and O-deficient n=5) studied by ultraviolet-resonance Raman scattering
This study shows that the quenching mechanism is electronically driven.
