Edge states and quantum optical high-harmonic generation from topological insulators
Christian Saugbjerg Lange, Lars Bojer Madsen
The strong-field process of high-harmonic generation (HHG) has, in recent years, been treated from a quantum optical perspective in the emerging research area of strong-field quant…
Limitations of an approximative phase-space description in strong-field quantum optics
Rasmus Vesterager Gothelf, Lars Bojer Madsen, Christian Saugbjerg Lange
In recent years, strong-field processes such as high-order harmonic generation (HHG) and above-threshold ionization driven by nonclassical states of light have become an increasing…
High-Order Harmonic Generation with Beyond-Semiclassical Emitter Dynamics: A Strong-Field Quantum Optical Heisenberg Picture Approach
Christian Saugbjerg Lange, Ella Elisabeth Lassen, Rasmus Vesterager Gothelf +1
Quantum-optical descriptions of strong-field processes have attracted significant attention in recent years. Typically, the theoretical modeling has been conducted in the Schröding…
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…
High-Harmonic Generation in a Crystal Driven by Quantum Light
Rasmus Vesterager Gothelf, Christian Saugbjerg Lange, Lars Bojer Madsen
We study intraband high-harmonic generation (HHG) in a crystal driven by quantum light. Previous theoretical studies have developed a framework based on coherent state expansions i…
Hierarchy of approximations for describing quantum light from high-harmonic generation: A Fermi-Hubbard model study
Christian Saugbjerg Lange, Lars Bojer Madsen
The quantum optical description of high-order harmonic generation where both the electrons of the generating medium and the driving and generated light fields are described quantum…
