Author(s): Achintya Bera, Koushik Pal, D. V. S. Muthu, Somaditya Sen, Prasenjit Guptasarma, U. V. Waghmare, and A. K. Sood The nontrivial electronic topology of a topological insulator is thus far known to display signatures in a robust metallic state at the surface. Here, we establish vibrational anomalies in Raman spectra of the bulk that signify changes in electronic topology: an E g 2 phonon softens unusually and its ... [Phys. Rev.
