"More is different: the beauty of multiband in
iron-based superconductors"
Prof. Hong Ding
(TD Lee Institute SJTU)
Abstract:
During this talk, I will highlight the
unnoticed beauty of multiband of iron-based superconductors, including:
1) Emergence of topological band which
coexists with superconductivity,
leading to the discovery of Majorana zero mode;
2) Interplay of multicomponent
superconductivity, leading to the discoveries of
exotic paring with time-reversal symmetry breaking and fractional
vortex;
3) Contribution of Hund coupling towards
pairing in this unique class of
superconductors.
About the Speaker:
Hong Ding, a chair professor of Tsung-Dao
Lee Institute, Shanghai Jiao Tong
University. He obtained BS degree in
physics from Shanghai Jiao Tong University
in 1990 and PhD degree in physics from
University of Illinois at Chicago in 1995.
He was a Postdoctoral Fellow in Argonne
National Laboratory from 1996 to 1998.
He was a faculty member of Department of
Physics at Boston College during 1998 –
2008. He was a Chief Scientist at the
Institute of Physics, Chinese Academy of
Sciences (CAS) during 2008 - 2022. He has
made several significant scientific
achievements, including discovery of
pseudogap in cuprate superconductors,
observation of s-wave superconducting gap
in iron-based superconductors,
discovery of Weyl fermions in solids, and
discovery of Majorana zero modes in
iron-based superconductors. He has
published more than 300 papers with total
citations over 20000. He received Sloan
Research Fellowship Award in 1999,
was elected as American Physical Society
Fellow in 2011, received Outstanding
Science and Technology Achievement Prize
of CAS in 2020, selected as New
Cornerstone Investigator in 2022, and
elected as an academician of CAS in 2023.
