Hamburg Photon Science Colloquium | Superconductivity without quasiparticle

by Jörg Schmalian (KIT Karlsruhe Institute of Technology, Karlsruhe, Germany)

Friday 20 Jan 2023, 14:00 → 15:30 Europe/Berlin

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.

Coffee, tea and cake will be served at 1:45 pm.
It is recommended to wear a FFP2-mask before, during and after the HHPS colloquium – also at the buffet. Thank you.
