Topological phase transitions via attosecond x-ray absorption spectroscopy
Juan F. P. Mosquera, Giovanni Cistaro, Mikhail Malakhov +6
We present a numerical experiment that demonstrates the possibility to capture topological phase transitions via an x-ray absorption spectroscopy scheme. We consider a Chern insula…

Circular dichroism in high-order harmonic generation: Heralding topological phases and transitions in Chern insulators
Alexis Chacón, Dasol Kim, Wei Zhu +10
Topological materials are of interest to both fundamental science and advanced technologies, because topological states are robust with respect to perturbations and dissipation. Ex…
