1. Fiber-laser-based noise-immune cavity-enhanced optical heterodyne molecular spectrometry
Sammanfattning : Noise-immune cavity-enhanced optical heterodyne molecular spectro-metry (NICE-OHMS) is one of the most sensitive laser-based absorption techniques. The high sensitivity of NICE-OHMS is obtained by a unique combination of cavity enhancement (for increased interaction length with a sample) with frequency modulation spectrometry (for reduction of noise).

2. Solar cavity receiver design for a dish-Stirling system
Sammanfattning : The growing concern for the climate change has led to an increasing research effort in renewable energy technologies in order to achieve a more sustainable electricity production. Concentrating Solar Power (CSP) is identified as a promising technology to deal with part of the future electricity production. LÄS MER
3. Strong light-matter coupling: from traditional to cavity-free polaritons
Sammanfattning : Polaritons are formed when light and matter interact strongly. For this to occur, photons and transitions in a material must exchange energy faster than the dissipation rate of the interacting components. Polaritons have shown the ability to change such material properties as photophysics, chemical reaction rates, transport, etc. LÄS MER
4. Strong Light-Matter Coupling: the Road from Conventional to Cavity-Free Polaritons
Sammanfattning : The interaction between light and matter is fundamental in perceiving and understanding the world. The interaction is typically weak, meaning light only perturbs matter without changing its properties. LÄS MER
5. Extended Jaynes-Cummings Models In Cavity Qed
Sammanfattning : Due to the improvement within cavity quantum electrodynamics experiments during the last decades, what was former seen as 'toy models' are today realized in laboratories. A controlled isolated coherent evolution of one or a few atoms coupled to a single mode inside a cavity is achievable. LÄS MER
