Inelastic Light Scattering in the Vicinity of a Single-Atom Quantum Point Contact in a Plasmonic Picocavity
Shuyi Liu, Franco P. Bonafe, Heiko Appel +3
Here, using low-temperature optical scanning tunneling microscopy (STM), we investigate inelastic light scattering (ILS) in the vicinity of a single-atom quantum point contact (QPC…
Berry Curvature Signatures in Chiroptical Excitonic Transitions
Samuel Beaulieu, Shuo Dong, Viktor Christiansson +10
The topology of the electronic band structure of solids can be described by its Berry curvature distribution across the Brillouin zone. We theoretically introduce and experimentall…
Nonlinear THz Control of the Lead Halide Perovskite Lattice
Maximilian Frenzel, Marie Cherasse, Joanna M. Urban +9
Lead halide perovskites (LHPs) have emerged as an excellent class of semiconductors for next-generation solar cells and optoelectronic devices. Tailoring physical properties by fin…
Observation of multi-directional energy transfer in a hybrid plasmonic-excitonic nanostructure
Tommaso Pincelli, Thomas Vasileiadis, Shuo Dong +15
Hybrid plasmonic devices involve a nanostructured metal supporting localized surface plasmons to amplify light-matter interaction, and a non-plasmonic material to functionalize cha…
Spectral narrowing of a phonon resonance in time-domain sum-frequency spectroscopy
Riko Kiessling, Martin Wolf, Alexander Paarmann
Sum-frequency generation (SFG) spectroscopy provides a versatile method for the investigation of non-centrosymmetric media and interfaces. Here, using tunable picosecond infrared (…
Second Harmonic Generation from Grating-Coupled Hybrid Plasmon-Phonon Polaritons
Marcel Kohlmann, Christian Denker, Nikolai C. Passler +4
Polaritons can provide strong optical field enhancement allowing to boost light-matter interaction. Here, we experimentally observe enhancement of mid-infrared second-harmonic gene…
