Superexchange mechanism and quantum many body excitations in the archetypal di-Cu oxo-bridge

Cédric Weber, Edward Baxter Linscott

The hemocyanin protein binds and transports molecular oxygen via two copper atoms at its core. The singlet state of the Cu2O2 core is thought to be stabilised by a superexchange pathway, but detailed in situ computational analysis is complicated by the mul ...

Origin of High-Frequency Radiation During Laboratory Earthquakes

François Xavier Thibault Passelègue

We monitor dynamic rupture propagation during laboratory stick-slip experiments performed on saw-cut Westerly granite under upper crustal conditions (10-90 MPa). Spectral analysis of high-frequency acoustic waveforms provided evidence that energy radiation ...

Predicting the thermal performance of thermochromic flat plate solar collectors

Andreas Schueler, Josef Andreas Schuler, Anna Krammer

A thermochromic vanadium dioxide (VO2) based absorber coating is proposed. The optical response of the multilayered absorber is first simulated, then, the spectral reflectance of the deposited absorber is measured. The determined solar absorptance and ther ...

Method of displaying an image on a see-through display

Sabine Süsstrunk, Adrien Birbaumer, Martinus Bosch

The present invention concerns a method of displaying an image on a see-through display. The method comprises: obtaining (101) a first electromagnetic radiation matrix of an object, the first matrix comprising first matrix elements representing radiation i ...

Local structural investigation of hafnia-zirconia polymorphs in powders and thin films by X-ray absorption spectroscopy

Reinis Ignatans

Despite increasing attention for the recently found ferro- and antiferroelectric properties, the polymorphism in hafnia- and zirconia-based thin films is still not sufficiently understood. In the present work, we show that it is important to have a good qu ...

Gas spectroscopy using low threshold mid-infrared radiation generated in Si3N4 waveguides

Tobias Kippenberg, Camille Sophie Brès, Hairun Guo, Davide Grassani, Fan Yang, Eirini Tagkoudi

We report trace-gas absorption spectroscopy based on the efficient generation of a 3.05μm dispersive wave in a Si3N4 waveguide pumped by a 2.09 μm femtosecond mode-locked fiber laser ...

Mechanisms of perfect absorption in nano-composite systems

Olivier Martin, Sebastian Mader

Recently, it was noted that losses in plasmonics can also enable several useful optical functionalities. One class of structures that can maximize absorption are metal insulator metal systems. Here, we study 3-layer systems with a nano-composite metal laye ...
