Attosecond pulse trains from graphene via macroscopic phase-matching in high harmonic generation
Sergio Martín-Domene, Luis Plaja, Carlos Hernández-García
Attosecond pulse generation in solids remains challenging due to the complex phase structure arising from multiple electronic pathways in high harmonic generation (HHG). Here, we i…

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…
