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…

Identification and properties of topological states in the bulk of quasicrystals

Frode Balling-Ansø, Jeppe Lykke Krogh, Ella Elisabeth Lassen +1

In contrast to the usual bulk-boundary correspondence, topological states localized within the bulk of the system have been numerically identified in quasicrystalline structures, t…

Interactions in Quantum Networks with Pulse Propagation Delays

Victor Rueskov Christiansen, Klaus Mølmer

The finite speed of light of pulses implies propagation delays between the generation of light, the interaction with different elements along its path and the final detection at th…
