초 록
Superconductivity has been surprising the physics community by continuously adding new types of superconductors. For the past decades, superconductivity research has been particularly fruitful thanks to the employment of the concept of topology. In this talk, I will briefly survey two possible topological superconductors that are attracting significant attention. First, I will introduce the youngest heavy-fermion superconductor UTe2 which is believed to realize a spin-triplet Cooper pairing. In the second half, I will talk about a completely new class of superconductivity, so-called high-spin superconductivity, which was proposed for unconventional superconductivity in topological semimetal YPtBi.
