  1. 1. Transverse Momentum Spectra in pp collisions (\sqrt{s}\) = 7 TeV and \(\sqrt{s}\) = 13 TeV in ALICE

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Andreas Stokkeland; [2023]
    Nyckelord :Multiplicity; Multiplicity classes; Soft interactions; Quark Gluon Plasma; QGP; transverse momentum; p_T; Chi-squared; fits; fit functions; Levy; Lévy; Exponential; BGBW; Boltzmann-Gibbs blast-wave; Fermi-Dirac; Bose-Einstein; Boltzmann; pion; kaon; proton; transverse momentum spectra; p_T spectra; surface velocity; Minimum Bias; MB; Physics and Astronomy;

    Sammanfattning : In this project particle production as a function of transverse momentum (\(p_{\rm T}\)) in proton-proton collisions at a center-of-mass energy (\(\sqrt{s}\)) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore gives information on the collision dynamics.

  3. 2. Mathematical modeling and analysis of hot carrier solar cells

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Benjamin van Dijk; [2023]
    Nyckelord :solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

    Sammanfattning : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. LÄS MER

  4. 3. A study of the gamma-ray emission from the blazar S50716+71 using the Fermi-LAT telescope

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Fredrik Vislander; [2022]
    Nyckelord :AGN; active galactic nuclei; Fermi-LAT; astrophysics; gamma-rays; synchrotron self-Compton; SSC; S50716 71.;

    Sammanfattning : This thesis sums up a bachelor project in which gamma-ray emission from an extra-galactic source (S50716+71) is studied using data collected by the Fermi Large Area Telescope (LAT). The emission consists of 12,5 years of data (April 2008 to February 2020) in the energy range 100 MeV - 300 GeV. LÄS MER

  5. 4. Theory of Time-Dependent Transport and Levitons in Nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik

    Författare :Jakob Westerberg; [2021]
    Nyckelord :leviton; Tkwant; tight-binding model; solid-state physics; time-dependent transport; scattering theory; quantum mechanics; computer simulation; nanowire; Physics and Astronomy;

    Sammanfattning : An interesting type of quasi-particles in solid-state materials are the so-called levitons. These are single- electron excitations above the Fermi-level that do not produce any hole states when carrying an integer multiple of the elementary charge. LÄS MER

  7. 5. Linear-scaling Quantum Molecular Dynamics for Reactive Systems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Linnéa Andersson; [2021]
    Nyckelord :;

    Sammanfattning : The purpose of this thesis is to demonstrate linear-scaling, energy stable, propagation of the electronic degrees of freedom in finite temperature ExtendedLagrangian Born-Oppenheimer Molecular Dynamics for reactive systems in aself-consistent charge density-functional tight-binding formulation. The inverse Jacobian kernel matrix in the electronic equation of motion is approximated using alow-rank combination of directional derivatives of the ground state residual function. LÄS MER
