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…
An ultrastrongly coupled single THz meta-atom
Shima Rajabali, Sergej Markmann, Elsa Jöchl +5
Free-space coupling to strongly subwavelength individual optical elements is a central theme in quantum optics, as it allows to control and manipulate the properties of quantum sys…
Breakdown of the topological protection by cavity vacuum fields in the integer quantum Hall effect
Felice Appugliese, Josefine Enkner, Gian Lorenzo Paravicini-Bagliani +6
The control of the electronic properties of materials via the vacuum fields of cavity electromagnetic resonators is one of the emerging frontiers of condensed matter physics. We sh…
Regenerative Terahertz Quantum Detectors
Paolo Micheletti, Jerome Faist, Tudor Olariu +3
Because of the ultrafast and photon-driven nature of the transport in their active region, we demonstrate that quantum cascade lasers can be operated as resonantly amplified terahe…
Dissipative Kerr solitons in semiconductor ring lasers
Bo Meng, Matthew Singleton, Johannes Hillbrand +3
Dissipative Kerr solitons are self-organized optical waves arising from the interplay between Kerr effect and dispersion. They can form spontaneously in nonlinear microresonators p…
Controlling Quantum Cascade Laser Optical Frequency Combs through Microwave Injection
Barbara Schneider, Filippos Kapsalidis, Mathieu Bertrand +4
In this work, control over the precise state emitted by quantum cascade laser frequency combs through strong radio-frequency current modulation close to their repetition frequency…
