  1. 1. Queering the Normal? : An intersectional study of gender identities and roles in the Late Iron Age cemeteries at Lovö, Sweden

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Leticia Tate; [2024]
    Keywords : Archaeology; Gender Studies; Queer Theory; Cemeteries; Burials; Iron Age; Scandinavia; Grave Goods; Intersectionality; Lovö; Identity; Arkeologi; genusvetenskap; queerteori; kyrkogårdar; begravningar; järnåldern; Skandinavien; gravgods; intersektionalitet; Lovö; identitet;

    Abstract : The purpose of this thesis is to analyse the relationship between grave goods and the identity of buried individuals. The interpretation of sex and gender, as well as gendered grave goods in Late Iron Age Scandinavia, is of a particular focus. READ MORE

  3. 2. Negotiating Unwanted Outsider Status- A study of Gang Subculture among Rohingya Refugees in Bangladesh

    University essay from Lunds universitet/Sociologi; Lunds universitet/Sociologiska institutionen

    Author : Sourav Das; [2023]
    Keywords : Rohingya; Rohingya Refugees; Gangs; Refugee Gang; Deviant Subculture; Gang Subculture; Moral Panic; Folk devils; Law and Political Science; Cultural Sciences; Social Sciences;

    Abstract : The emergence of the refugee gang subculture has changed its focus from being a regional to a worldwide problem, drawing on the findings of previous studies. Many past studies suggest that the massive influx of Rohingya refugees from Myanmar has not only amplified existing socioeconomic challenges but has also fueled concerns within the host population in Bangladesh regarding organized gang violence.

  4. 3. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

  5. 4. First Principles Studies Of 2D Magnets

    University essay from

    Author : Yahya Fayazi; Linus Jacobsson; Folke Gustafsson; [2022]
    Keywords : 2D material; ab initio; magnet; Quantum Espresso; Density Functional Theory; DFT; CrCl3; CrBr3; CrI3; 2D material; 2 dimensionella material; två dimensionella material;

    Abstract : The aim of this project is to examine the electric and magneticproperties of three monolayer chromium trihalides when doped withdifferent transitions metals, that is CrXY_6, where X=(Mn,Fe,Co,Ni,V)and Y=(Cl,Br,I). The calculations were made using the software programQuantum Espresso that used density functional theory to solveSchrödinger’s equation. READ MORE

  6. 5. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects

    University essay from Lunds universitet/Matematisk fysik

    Author : Josefin Reftlér; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. READ MORE
