Abstract Flat electronic bands in condensed matter provide a rich avenue for exploring novel quantum phenomena. Here, we report an optical spectroscopy study of a topological hourglass semimetal Nb$_{3}$SiTe$_{6}$ with the electric field of the incident light parallel to its crystalline $ab$-plane. The $ab$-plane optical conductivity spectra of Nb$_{3}$SiTe$_{6}$ single crystals exhibit a remarkable peak-like feature around 1.20 eV, which is mainly contributed by the direct optical transitions between the two ab-initio-calculation-derived flat bands along the momentum direction $Z$-$U$. Our results pave the way for investigating exotic quantum phenomena based on the flat bands in topological hourglass semimetals.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
