  • Kaminski, Matthias; Landsteiner, Karl; Mas, Javier; Shock, Jonathan P.; Tarrío, Javier (2010-02-04)
    We provide a framework for calculating holographic Green’s functions from general bilinear actions and fields obeying coupled differential equations in the bulk. The matrix-valued spectral function is shown to be independent ...
  • Amado, Irene; Kaminski, Matthias; Landsteiner, Karl (2009-05-06)
    We study the poles of the retarded Green functions of a holographic superconductor. The model shows a second order phase transition where a charged scalar operator condenses and a U(1) symmetry is spontaneously broken. ...
  • Kaminski, Matthias; Landsteiner, Karl; Pena-Benitez, Francisco; Erdmenger, Johanna; Greubel, Constantin; Kerner, Patrick (2010-03-25)
    We present an analysis and classification of vector and scalar fluctuations in a D3/D7-brane setup at finite temperature and baryon density. The system is dual to an N = 2 supersymmetric Yang-Mills theory with SU(Nc) ...
