Many-body effects on high-harmonic generation in Hubbard ladders
Yuta Murakami, Thomas Hansen, Shintaro Takayoshi +2
We show how many-body effects associated with background spin dynamics control the high-harmonic generation (HHG) in Mott insulators by analyzing the two-leg ladder Hubbard model.…

Noninteger high-harmonic generation from extended correlated systems
Christian Saugbjerg Lange, Thomas Hansen, Lars Bojer Madsen
The spectra produced by high-harmonic generation (HHG) typically exhibit well-defined peaks at odd integers times the laser frequency. However, in recent investigations of HHG from…
