  1. 1. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oskar Sundberg; [2023]
    Keywords : geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Abstract : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. READ MORE

  3. 2. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Erik Rustas; [2023]
    Keywords : Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : This thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry.

  4. 3. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Filip Gustavsson; [2023]
    Keywords : Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

    Abstract : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. READ MORE

  5. 4. Phenomenological exploration of flavored Grand Unification through high-scale matching and renormalization group flow

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Hector Tiblom; [2023]
    Keywords : Grand Unification; GUT; trinification; spontaneous symmetry breaking; effective field theory; EFT; high-scale matching; renormalization group flow; Physics and Astronomy;

    Abstract : The phenomenological success of the Standard Model (SM), and its unification of the electromagnetic and weak forces has inspired the search for a Grand Unified Theory (GUT), that dynamically reduces to the SM at low energies. In this work, we consider one such GUT, based on the trinification model [SU(3)]³ with an additional local SU(2) family symmetry, that is then broken directly to the gauge symmetry group of the SM.

  6. 5. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Vikramjeet Das; [2023]
    Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE
