  • Critical Wess-Zumino models with four supercharges in the functional renormalization group approach 
    Feldmann, Polina; Wipf, Andreas; Zambelli, Luca (College Park : American Physical Society (APS), 2018)
    We analyze the N = 1 supersymmetric Wess-Zumino model dimensionally reduced to the N = 2 supersymmetric model in three Euclidean dimensions. As in the original model in four dimensions and the N = (2, 2) model in two ...
  • Matrix product states and variational methods applied to critical quantum field theory 
    Milsted, Ashley; Haegeman, Jutho; Osborne, Tobias J. (College Park, MD : American Physical Society, 2013)
    We study the second-order quantum phase transition of massive real scalar field theory with a quartic interaction in (1+1) dimensions on an infinite spatial lattice using matrix product states. We introduce and apply a ...
  • Noncommutative multi-instantons on R-2n x S-2 
    Ivanova, Tatiana A.; Lechtenfeld, Olaf (Amsterdam : Elsevier, 2003)
    Generalizing self-duality on R-2 x S-2 to higher dimensions, we consider the Donaldson-Uhlenbeck-Yau equations on R-2n x S-2 and their noncommutative deformation for the gauge group U(2). Imposing SO(3) invariance (up to ...
