  1. 1. Quantum Simulation of Quantum Effects in Sub-10-nm Transistor Technologies

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialteori

    Författare :Anders Winka; [2022]
    Nyckelord :Transistor Modeling; Quantum Transport; QTBM; Block Cyclic Reduction; Quantum Computing; Quantum Annealer;

    Sammanfattning : In this master thesis, a 2D device simulator run on a hybrid classical-quantum computer was developed. The simulator was developed to treat statistical quantum effects such as quantum tunneling and quantum confinement in nanoscale transistors. LÄS MER

  3. 2. Numerical solutions to the Boussinesq equation and the Korteweg-de Vries equation

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Filip Sjölander; [2021]
    Nyckelord :;

    Sammanfattning : The aim of the report is to numerically construct solutions to two analytically solvable non-linear differential equations: the Korteweg–De Vries equation and the Boussinesq equation. To accomplish this, a range of numerical methods where implemented, including Galerkin methods. LÄS MER

  4. 3. On two-component Bose-Einstein condensates in a ring

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Marcus Sköld; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : A Bose-Einstein condensate is a type of gas consisting of one or more types of particles called bosons which are cooled to a temperature very close the absolute zero. Under these conditions the particles all start to occupy their lowest quantum state. LÄS MER

  5. 4. Dependency of high-order harmonics to polarisation properties of many-cycle driving fields

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Timothé Ramboazanaka; [2018]
    Nyckelord :Atomic physics; attosecond pulses; high-order harmonic generation; polarisation; polarisation state; electron wave packet trajectory; three-step model; time-dependent schrödinger equation; TDSE; two-colour; selection rules; symmetry; conservation laws; Physics and Astronomy;

    Sammanfattning : Light-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. LÄS MER

  7. 5. Numerical continuation of standing waves for the Davey-Stewartson equation

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Teo Nilsson; [2016]
    Nyckelord :Numerical continuation standing waves Davey Stewartson nonlinear Schrödinger equation ground excited state; Mathematics and Statistics;

    Sammanfattning : This thesis considers solitary standing wave solutions to the Davey-Stewart-son equation, which is a model for surface waves on a body of water in three dimensions. In a special case, the Davey-Stewartson equation is reduced to the well-known non-linear Schrödinger equation with cubic power which is known to have a countable familiy of radial standing waves.
