Multi-dimensional parameter space of higher-order exceptional points induced by Brillouin optoacoustics
Grigorii Slinkov, Anton Montag, Julius T. Gohsrich +4
Exceptional points (EPs) are degeneracies in the spectrum of non-Hermitian systems, where both the eigenvalues and eigenvectors coalesce. In the vicinity of an n-th order EP, the e…
Higher-order exceptional points in a multimode continuum optoacoustic system
Anton Montag, Julius T. Gohsrich, Quentin Levoy +2
Exceptional points appear in non-Hermitian systems as degeneracies, where not only eigenvalues but also eigenvectors coalesce. They are of great theoretical and experimental intere…
Giant Brillouin gain in frozen CS2 capillaries
Simon Seiderer, Andreas Geilen, Luan N. Sliwa +5
Stimulated Brillouin-Mandelstam scattering offers exceptional capabilities for photonic signal processing, but current platforms demand performance trade-offs between long interact…
Brillouin-Mandelstam Scattering-based Cooling of Traveling Acoustic Waves from Cryogenic Temperatures
Lisa Fischer, Laura Blázquez MartÃnez, Robin Chenivière +2
Thermal phonons are a major source of decoherence in quantum mechanical systems. Operating in the quantum ground state is therefore often an experimental prerequisite. Additionally…
Cavity-less Brillouin strong coupling in a solid-state continuous system
Laura Blázquez MartÃnez, Changlong Zhu, Birgit Stiller
Strongly coupling two systems allows them to exchange coherent information before the systems decohere. This important regime in light-matter interactions has predominantly been re…
