  1. 1. Modelling Gas Flow Behaviour in Gas Atomizer

    University essay from KTH/Materialvetenskap

    Author : Aravind Senan Vasanthasenan Reji; [2022]
    Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

  3. 2. Holographic RG-flows and the Domain-Wall/Cosmology correspondence

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Jean-François Vaduret; [2022]
    Keywords : holography; cosmology; domain-wall; AdS; CFT; correspondence;

    Abstract : In this master thesis we investigate implications of the Domain-Wall/Cosmology (DW/C) correspondence on one-point functions of holographic RG-flows. The thesis gives a detailed computation of linearized gauge-invariant Einstein equations in (d+1) dimensions while making the DW/C correspondence explicit. READ MORE

  4. 3. Micromagnetic Study of Current Induced Domain Wall Motion for Spintronic Synapses

    University essay from Uppsala universitet/Energimaterialens fysik

    Author : Dimitrios-Petros Petropoulos; [2021]
    Keywords : computational physics; micromagnetism; micromagnetic simulations; Mumax3; current induced domain wall motion; domain wall driving; spin current; spin transfer torque; synapse; memristor; Neuromorphic computing; spintronic; brain inspired computing; Permalloy; nanowire; nanostrip; notches;

    Abstract : Neuromorphic computing applications could be made faster and more power efficient by emulating the function of a biological synapse. Non-conventional spintronic devices have been proposed that demonstrate synaptic behavior through domain wall (DW) driving. READ MORE

  5. 4. Domain wall solutions in the AdS/CFT correspondence

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Eduardo Mateos González; [2020]
    Keywords : AdS CFT correspondence; BW QFT correspondence;

    Abstract : In this thesis we study a particular realization of the Domain wall/Quantum Field Theory correspondence, a modification of the Anti de-Sitter/Conformal Field Theory correspondence that is used to study deformations of a Conformal Field Theory. In theQuantum gravity side of the duality we analyze a N = 1 gauged supergravity theory in 7 dimensions which presents two different Anti de-Sitter vacua, one of which preserves the full supersymmetry and one that breaks half of the supercharges.

  6. 5. GPPZ and the Holographic Triforce against Scalars

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Jean-François Vaduret; [2019]
    Keywords : String theory; holography; RG-flow; gppz; domain wall; AdS; CFT;

    Abstract : We use gauge-invariant cosmological perturbation theory to compute one-point functions of active and inert scalar fields of the GPPZ RG-flow in AdS5. Linearized Einstein equations are computed and made gauge-invariant for D-dimensional Euclidean domain-wall geometry. READ MORE
