Superconductivity without quasiparticles

Charlista: Prof. Joerg Schmalian, Karlsruhe Institute of Technology

Resumen: Superconductivity is abundant near quantum-critical points, where fluctuations suppress the formation of Fermi liquid quasiparticles and the Bardeen-Cooper-Schrieffer theory no longer applies. Holographic superconductivity, rooted in the duality of quantum field theory and gravity theory, has been proposed to describe such systems. We derive holographic superconductivity in form of a gravity theory with emergent space-time from a quantum many-body Hamiltonian.
