  1. 1. Continuous Quantum Control of Quantum Dot Systems

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Holst; [2022]
    Keywords : Quantum Control; Quantum Fokker-Planck Master Equation; Maxwell s demon; Quantum dots; Full counting statistics; Generalized Quantum Measurements; Thermodynamics; Physics and Astronomy;

    Abstract : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. READ MORE

  3. 2. Electrodynamic field at spatial infinity

    University essay from KTH/Fysik

    Author : Jakob Myhrman; [2022]
    Keywords : Spatial infinity; Conformal rescaling; Minkowski space; Penrose Diagram; Einstein universe; Newman-Penrose formalism; Sigma-process; Resolution of singularities; Maxwell s equations; Cylinder at spatial infinity; Rumslig oändlighet; Konform omskalning; Minkowski rummet; Penrose Diagram; Einsteins universum; Newman-Penrose formalismen; Sigma-processen; Singularitetupplösning; Maxwells ekvationer; Cylindern vid rumslig oändlighet;

    Abstract : The treatment of spatial infinity is one of the remaining major open problems in the theory of isolated self-gravitating systems. Especially when one wants to model scattering of gravitational radiation in spacetime. In this thesis the conformal theory is used to study simple electromagnetic fields, close to spatial infinity.

  4. 3. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

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

    Author : Mohammadjavad Javadi; [2020]
    Keywords : Corona discharge; Suppression ring; High voltage capacitor banks;

    Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.

  5. 4. On the Existence of Electrodynamics on Manifold-like Polyfolds

    University essay from Umeå universitet/Institutionen för fysik

    Author : Aron Persson; [2019]
    Keywords : ;

    Abstract : This essay examines the question whether the classical theory of electrodynamics can be extended to a spacetime which locally changes dimension and if such an endeavour is mathematically possible. Recent research has developed a new generalisation of smooth manifolds, the so called M-polyfolds, which constitutes a sufficient foundation to make this endeavour a physical plausibility. READ MORE

  6. 5. Multiple electromagnetic scattering by spheres using the T-matrix formulation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Marina Wallin; [2015]
    Keywords : T-matrix; Multiple scattering; RCS; FDTD; Electromagnetic scattering; Mie scattering;

    Abstract : Low observable technology is used in order to prevent detection, or to delay detection. Radar cross section is an important parameter in aircraft survivability since it measures how detectable an object is with radar. To find the radar cross section Maxwell's equations are solved numerically in the time-domain using a finite difference scheme. READ MORE
