TOPIC
▸　Nickelate Superconductivity: a New Paradigm of High-Temperature Superconductivity

❝　The materialization of superconductivity at technologically relevant temperatures has been a longterm pursuit since the discovery of superconductivity in mercury. So far only a very few materials families of “high-temperature” superconductors have been discovered: the cuprates in 1986 ^[1], iron pnictides and chalcogenides in 2008 ^[2], super-hydrides in 2015 ^[3], and very recently, nickelates in 2023 ^[4]. In this talk, I will briefly review the phenomenology of high-temperature superconductivity, discuss the common features shared by these materials, and highlight the outstanding problems and research opportunities in this field. An emphasis will focus on the latest member to this select materials club: the layered nickelates.　❞

❝　Dr. Hsu received his BSc in Materials Science and Engineering from National Tsing Hua University in Taiwan, MS in Materials Physics from Linköping University in Sweden, and PhD in Physics from Cambridge University in the UK. In 2018 he moved to the High Field Magnet Laboratory at Radboud University in Nijmegen, the Netherlands as a postdoc researcher, and he is currently a research scientist at Radboud University working with Prof. Nigel Hussey. In 2024 he joined NTHU Physics as an Assistant Professor and start his own group. His current research interests include complex oxides, unconventional superconductivity, anomalous metallicity, and high-sensitivity experiments under high magnetic fields.　❞
