  4. 8. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    University essay from KTH/Nanostrukturfysik

    Author : Milton Persson; [2019]
    Keywords : Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Abstract : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

  5. 9. Giant planet formation around HR8799

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Dan Wallsby; [2017]
    Keywords : HR8799; Planet formation; Protoplanetary disks; Giant planets; Astronomy; Migration; Dynamics; Physics and Astronomy;

    Abstract : In the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. READ MORE

  6. 10. Development of a location-based taxi service : using open-source tools

    University essay from Mittuniversitetet/Avdelningen för data- och systemvetenskap
