Nonlinear optical observation of coherent acoustic Dirac plasmons in thin-film topological insulators
Low-energy collective electronic excitations exhibiting sound-like linear dispersion have been intensively studied both experimentally and theoretically for a long time. However, coherent acoustic plasmon modes appearing in time-domain measurements are rarely observed due to Landau damping by the si...
