Charge creation via quantum tunneling in one-dimensional Mott insulators: A numerical study of the extended Hubbard model
Thomas Hansen, Lars Bojer Madsen, Yuta Murakami
Charge creation via quantum tunneling, i.e. dielectric breakdown, is one of the most fundamental and significant phenomena arising from strong light(field)-matter coupling. In this…
Excitonic Enhancement of Squeezed Light in Quantum-Optical High-Harmonic Generation From a Mott Insulator
Christian Saugbjerg Lange, Thomas Hansen, Lars Bojer Madsen
The strong-field induced generation of nonclassical states of light is not only a subject of fundamental research but also has potential usage in quantum information science and te…
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…
Electron-correlation induced nonclassicallity of light from high-harmonic generation
Christian Saugbjerg Lange, Thomas Hansen, Lars Bojer Madsen
We study the effect of electron-electron correlations on the quantum state of the light emitted from high-harmonic generation (HHG). The quantum state of the emitted light is obtai…
