HKIQST Colloquium: “More is different: the beauty of multiband in iron-based superconductors” by Prof. DING Hong on Friday, December 13, 2024, 10:30 am LG1 – CYPP3, Chong Yuet Ming Physics Building, HKU

During this talk, the unnoticed beauty of multiband of iron-based superconductors will be highlighted, including i) emerge of topological band which coexists with superconductivity, leading to the discovery of Majorana zero mode; ii) Interplay of multicomponent superconductivity, leading to the discovery of exotic paring with time-reversal symmetry breaking and fractional vortex; iii) Contribution of Hund coupling  towards pairing in this unique class of superconductors.
