  1. 1. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains

    University essay from Uppsala universitet/Materialteori

    Author : Emil Beiersdorf; [2023]
    Keywords : Quantum chirality; chirality; spin interaction; Heisenberg interaction; DM interaction; quantum physics; quantum mechanics; molecular nanomagnet; mathematical physics; theoretical physics; Kvantkiralitet; kiralitet; spinninteraktioner; Heisenberginteraktion; DMinteraktion; kvantfysik; kvantmekanik; molekylär nanomagnet; matematisk fysik; teoretisk fysik;

    Abstract : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. READ MORE

  3. 2. 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.

  4. 3. Theory and Modeling of Electrical Control of Chiral Qubit in Spin-Frustrated Molecular Triangle

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Shirin Hakimi; [2019]
    Keywords : quantum computers; spinfrustration;

    Abstract : Spin-frustrated molecular triangles have four low-lying energy states, so called chiral states, which can be employed as the unit of information, qubit, in a quantum computer. The fact that the chiral states are characterized by two quantum numbers chirality and spin allows the control of the magnetization of the molecule by an electric field due to the spin-electric interaction.
