Robustness of topologically sensitive harmonic generation in laser-driven linear chains
Robustness of topologically sensitive harmonic generation in laser-driven linear chains
A huge difference in the harmonic yield from the two topological phases of finite, dimerizing linear chains in laser fields has recently been observed in all-electron time-dependent density functional simulations [D. Bauer, K.K. Hansen, Phys. Rev. Lett. 120, 177401 (2018)]. In this work, we explore the robustness of the effect …
