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…
Ultrafast Nonequilibrium Dynamics in Two-dimensional Quantum Spin-Hall Materials
Rajesh K. Malla, Dasol Kim, Dong Eon Kim +2
We develop the theoretical framework of nonequilibrium ultrafast photonics in monolayer quantum spin-Hall insulators supporting a multitude of topological states. In these material…
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…
Phase matching effects in high harmonic generation at the nanometer scale
Manuel Blanco, Carlos Hernández-García, Alexis Chacón +3
Plasmon resonances are known to amplify the electromagnetic fields near metallic nanostructures. Therefore, they are considered to provide a promising scheme to generate extreme-ul…
