  1. 41. Order in Strongly Correlated Quasi-One-Dimensional Systems : Solving Higher-Dimensional Systems Combining Matrix-Product-State Methods and Mean-Field Theory

    Författare :Gunnar Bollmark; Adrian Kantian; Annica M. Black-Schaffer; Fabian Heidrich-Meisner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; strongly correlated systems; matrix-product states; quasi-one-dimensional; Hubbard model; mean-field theory; first-principles calculations.; Fysik; Physics;

    Sammanfattning : Since their discovery the understanding of unconventional superconductors (USCs) has posed a great challenge in condensed matter physics. One central problem, both of theory and experiment, lies in determining the microscopic origin of electron pairing in such systems. LÄS MER

  3. 42. Understanding Intergenerational Mobility : Inequality, Student Aid and Nature-Nurture Interactions

    Författare :Gunnar Brandén; Mikael Lindahl; Björn Öckert; Erik Lindqvist; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intergenerational mobility; inequality; student aid; adult education; difference-in-differences; propensity scores; Economics; Nationalekonomi;

    Sammanfattning : Essay I: A body of evidence has emerged in the literature on intergenerational mobility documenting that unequal countries experience less social mobility: a relationship known as the Great Gatsby Curve. In this paper I estimate the Great Gatsby Curve within Sweden across 125 commuting zones and 20 cohorts, exploiting both cross-sectional and longitudinal variation. LÄS MER
