Holographic superconductors and the effect of back-reaction

Oct. 21 - 14:30 - 2014

SPEAKER: Betti Hartmann (Jacobs University)


ABSTRACT: The AdS/CFT correspondence suggests that strongly coupled Conformal Field Theories (CFT) in d dimensions are dual to gravity theories in (d+1)-dimensional Anti-de Sitter (AdS) space-time and as such constitutes a realization of the holographic principle.
The question remains whether this duality can be tested and verified.
One suggestion is to use the correspondence to make predictions about the experimentally observed phenomenon of high-temperature superconductivity for which - up to now - no consistent microscopic theory in condensed matter physics exists.
In this talk, I will mainly discuss holographic superconductors away from the probe limit, i.e. taking back-reaction of  the space-time into account by solving the full set of coupled matter and gravity equations.
I will demonstrate that this leads to some important changes in the qualitative and quantitative features as compared to the probe limit with a fixed space-time background.
