Licht- und Schallwellen enthüllen negativen Druck
Negativer Druck ist ein seltenes und schwer nachzuweisendes Phänomen in der Physik. Mithilfe von flüssigkeitsgefüllten optischen Fasern und Schallwellen haben Forscher*innen des Max-Planck-Instituts für die Physik des Lichts (MPL) in Erlangen jetzt eine neue Methode entdeckt, um negativen Druck zu…

Group summer events
Kayaking group event in the Fränkische Schweiz and testing our new apero hour on Fridays at the institute!
Trapping an easvesdropper using localized optoacoustic detection
Our new work on "Eavesdropper localization for quantum and classical channels via nonlinear scattering" is on the arXiv!
Abstract:
Optical fiber networks are part of important critical infrastructure and known to be prone to eavesdropping attacks. Hence cryptographic methods have to be used to…
New paper on the arxiv: strong optoacoustic cooling
Read about our new work on strong optoacoustic cooling of a 50cm-long acoustic wave by 219 K from room temperature:
Abstract:
We experimentally demonstrate optoacoustic cooling via stimulated Brillouin-Mandelstam scattering in a 50 cm-long tapered photonic crystal fiber. For a 7.38 GHz acoustic…
