Generation of circular polarized high-order harmonics from single color quantum light

Lidija Petrovic, Philipp Stammer, Maciej Lewenstein +1

The atomic response to an ultra-intense driving field produces a characteristic high-harmonic spectrum featuring a rapid drop in intensity for the lower harmonics, followed by a pl…

Quantum Optics and Quantum Electrodynamics of Strong Field Processes

Marcelo F. Ciappina, Misha Yu. Ivanov, Maciej Lewenstein +3

In its beginnings, the physics of intense laser-matter interactions was the physics of multiphoton processes. The theory was reduced then to high-order perturbation theory, while t…

Propagation of intense squeezed vacuum light in non-linear media

Javier Rivera-Dean, Deeksha Kanti, Philipp Stammer +5

Recent developments in quantum light engineering have enabled the use of infrared bright squeezed vacuum (BSV) femtosecond pulses in highly nonlinear optics, particularly strong fi…

Microscopic analysis of above-threshold ionization driven by squeezed light

J. Rivera-Dean, P. Stammer, C. Figueira de Morisson Faria +1

Above-threshold ionization (ATI) is a strong-field-driven process where electrons absorb more photons than required for ionization. While ATI dynamics and outputs are well-understo…

Theory of quantum optics and optical coherence in high harmonic generation

Philipp Stammer, Javier Rivera-Dean, Maciej Lewenstein

Optical coherence encodes information about the correlations of the electromagnetic field. In combination with quantum optical approaches, it allows for the study of the correlatio…

Structured squeezed light allows for high-harmonic generation in classical forbidden geometries

J. Rivera-Dean, P. Stammer, M. F. Ciappina +1

High-harmonic generation (HHG) is a nonlinear process in which a strong driving field interacts with a material, resulting in the frequency up-conversion of the driver into its hig…
