Frontiers Science Forum 94: Probing the superconducting gap of iron-based superconductors through photoelectrons – a path towards a unified paradigm of high-Tc superconductivity (Pro. Ding Hong, Nov.06, 2012)

Frontiers Science Forum 94

Title: Probing the superconducting gap of iron-based superconductors through photoelectrons – a path towards a unified paradigm of high-Tc superconductivity

Speaker: Prof. Ding Hong, Institute of Physics, CAS

Time and place: 15:00-16:00pm, Nov. 06, 2012, Room 111, Physics Building

 

Abstract:

In this talk, I will present our angle-resolved photoemission spectroscopy (ARPES) results on iron-based superconductors, mainly focus on high-resolution measurements of their superconducting gaps. All gaps observed can be well described simple local pairing functions, which can be fully determined by local antiferromagnetic (AF) exchange interactions and Fermi surface (FS) topology. We argue the same is true for the high-Tc CuO-based superconductors, whose high critical temperatures and d-wave gap function are also the consequences of their large nearest-neighboring AF superexchange and FS topology. Thus we believe that strong local AF exchanges and collaborative FS topology is a possible unified paradigm of high-Tc superconduct
