Giant phonon anomaly in topological nodal-line semimetals

Giant phonon anomaly in topological nodal-line semimetals

The band topology has been revealed to bring a wide array of novel electronic transport phenomena, but its interaction with phonon properties remains largely unexplored. Here we propose that continuous topological singularities with variable Fermi wave vectors can lead to giant effects on phonon tra...
