  1. 1. The black hole information paradox and holography

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Ona Mola Bertran; [2023]
    Keywords : information paradox; semiclassical physics; holography; AdS CFT correspondence; island formula; entanglement entropy;

    Abstract : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. READ MORE

  3. 2. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  4. 3. Transportation Study of Release from a Space Elevator to Cislunar Space

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Daniel Griffin; [2023]
    Keywords : Space Elevator; Cislunar Space; Mass Transportation; Astronaut Safety; Apex Anchor; Rymdhiss; Cislunar-rymden; Masstransport; Astronautsäkerhet; Apex-ankaret;

    Abstract : To leave Earth’s gravity well and ascend into Cislunar space takes ingenuity, and the engineering feats of many. Now to propel humanity further into space, rockets will need assistance to provide the large requirements of mass to be used for space structures. READ MORE

  5. 4. Constraining the Higgs width in Higgs production associated with a top quark pair

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

    Author : Benjamin Dahlén; [2023]
    Keywords : Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Abstract : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

  6. 5. Beyond Distance: Understanding the Trade Disadvantage of the Sub-Saharan African Landlocked Countries

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Mai Ahrne Bojang; [2023]
    Keywords : Landlocked; Gravity model; Sub-Saharan Africa; European Union; International trade; Business and Economics;

    Abstract : This paper analyses the magnitude of exports of the landlocked countries of Sub-Saharan Africa to the European Union and attempts to find an explanation for the low trade flows of the region. Understanding the cause of the limited trade of landlocked countries in the region is important to enable successful implementation of trade enhancing policies and reforms. READ MORE
