摘要
Unconventional superconductivity and topological quantum phenomena are two frontier research directions of condensed matter physics. In this special topic, we collect several works covering important progress in these two directions. Superconductivity was discovered in Hg in 1911 by the group of Kamerling Onnes in Leiden （Holland）.
