  1. 1. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    University essay from KTH/Tillämpad fysik

    Author : Daniele Lopriore; [2022]
    Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

  3. 2. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Karolina Dorozynska; [2015]
    Keywords : Slow light; Whispering Gallery Mode Resonator; WGMR; Atomic physics; Physics and Astronomy;

    Abstract : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. READ MORE

  4. 3. NUMERICAL SIMULATIONS OF FRICTION-INDUCED NOISE OF AUTOMOTIVE WIPER SYSTEMS

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Océane Roure; [2015]
    Keywords : Squeal noise; wiper system; numerical simulations; finite element model; mode-coupling; design of experiments; Farmer diagram;

    Abstract : Automotive parts may be the cause of very annoying friction-induced noise and the source of many customer complaints. Indeed, when a wiper operates on a windshield, vibratory phenomena may appear due to flutter instabilities and may generate squeal noise. READ MORE

  5. 4. High-chromaticity Optics for the MAX IV 3 GeV Storage Ring

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Teresia Olsson; [2013]
    Keywords : electron accelerator; MAX IV; storage ring; beam dynamics; chromaticity; Physics and Astronomy; Technology and Engineering;

    Abstract : The MAX IV facility is a 3rd generation state-of-the-art synchrotron light source currently under construction in Lund, Sweden. The MAX IV 3 GeV storage ring has a large negative natural chromaticity, which has to be corrected to positive values to prevent head-tail instabilities. READ MORE
