Third order nonlinear correlation of the electromagnetic vacuum at near-infrared frequencies
Francesca Fabiana Settembrini, Alexa Herter, Jèrôme Faist
In recent years, electro-optic sampling, which is based on Pockel's effect between an electromagnetic mode and a copropagating, phase-matched ultrashort probe, has been largely use…
Probing Vacuum Field Fluctuations and Source Radiation Separately in Space and Time
Frieder Lindel, Alexa Herter, Jérôme Faist +1
Source radiation (radiation reaction) and vacuum-field fluctuations can be seen as two inseparable contributions to processes such as spontaneous emission, the Lamb shift, or the C…
Detection of quantum-vacuum field correlations outside the light cone
Francesca Fabiana Settembrini, Frieder Lindel, Alexa Marina Herter +2
According to quantum field theory, empty space -- the ground state of the theory with all real excitations removed -- is not empty at all, but filled with quantum-vacuum fluctuatio…
Electric field correlation measurements on the electromagnetic vacuum state
Ileana-Cristina Benea-Chelmus, Francesca Fabiana Settembrini, Giacomo Scalari +1
Quantum mechanics ascribes to the ground state of the electromagnetic radiation zero-point electric field fluctuations that permeate empty space at all frequencies. No energy can b…
Magneto-transport controlled by Landau polariton states
Gian L. Paravicini-Bagliani, Felice Appugliese, Eli Richter +10
Hybrid excitations, called polaritons, emerge in systems with strong light-matter coupling. Usually, they dominate the linear and nonlinear optical properties with applications in…
Sub-cycle measurement of intensity correlations in the Terahertz range
Ileana-Cristina Benea-Chelmus, Curdin Maissen, Giacomo Scalari +2
The Terahertz frequency range bears intriguing opportunities, beyond very advanced applications in spectroscopy and matter control. Peculiar quantum phenomena are predicted to lead…
