  1. 1. d-wave Josephson Junctions

    Författare :Tobias Lindström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; high-temperature superconductivity; Andreev states;

    Sammanfattning : The properties of d-wave YBCO Josephson junctions and dc-SQUIDs with high misorientation angles have beenstudied experimentally .The predominant d-wave symmetry of the pairing wavefunction in high-Tc superconductors has, to a large extent, beena hinderance in applications, but it also makes it possible to fabricate devices with novel properties that may be suitablefor applications in the quantum regime; one particulary interesting property is a strong second harmonic component in the current-phase relation ofjunctions with the electrodes oriented in a node-lobe arrangement; so-called 0-45 junctions.

  3. 2. Dynamics of high-angle grain boundary YBCO Josephson junctions

    Författare :Tobias Lindström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes experimental investigations of properties of high-angle YBa2Cu3O7−δ(YBCO)bicrystal Josephson junctions and SQUIDs fabricated on SrTiO3-substrates. The main focus of theinvestigation has been on the effects of the predominant d-wave symmetry of the superconductingwavefunction in YBCO on transport properties and dynamics. LÄS MER

  5. 4. Comforting an orphaned nation : Representations of international adoption and adopted Koreans in Korean popular culture

    Författare :Tobias Hübinette; Staffan Rosén; Lars Lindström; Koen De Ceuster; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Korean studies; international adoption; adopted Koreans; postcolonial studies; cultural studies; nationalism; diaspora; representation; popular culture; reconciliation; Koreanology; Koreanologi;

    Sammanfattning : This is a study of popular cultural representations of international adoption and adopted Koreans in Western countries. The study is carried out from a postcolonial perspective and uses a cultural studies reading of four feature films and four popular songs as primary sources. LÄS MER

  7. 5. Stadens gränsplatser : Kungliga Poliskammaren och vardagens omstridda rum i Stockholm, 1776–1835

    Författare :Tobias Osvald; Dag Lindström; Henrik Ågren; Magnus Linnarsson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Police; policing; borders; Stockholm; urban space; public; private; 18th century; 19th century; contestation; negotiation; everyday life; micro-geographies; homelessness; sleeping rough; keeping pub; sanitation; order; control; social practice theory; flows; transgressions; closure; stabilization; movement; Historia; History;

    Sammanfattning : This dissertation explores the interaction between the inhabitants of Stockholm and the constables of the Royal Police Chamber—Sweden’s first police force—during a period in the city’s history that is associated with stagnation from the perspectives of demography and economy. The aim is to understand how space was negotiated and changed over time through everyday interactions and practices. LÄS MER
