Abstract
The interplay between density wave (DW) and superconductivity (SC) has been one of the most intriguing and extensively studied phenomenon in condensed matter physics, as SC is often found to develop on the background of a DW order. However, despite an extensive research effort, the relation between DW ordering and SC is not yet elucidated. Titanium-based pnictide oxides, sharing similarities in both crystal and band structures with cuprates and Fe-based superconductors, also exhibit DW ordering in the normal state and thus are considered as another great platform for seeking unconventional superconductors. In this review, we comprehensively summarize the recent progress and essential aspects of the normal and superconducting state in superconducting titanium-based pnictide oxides, together with the topological state in them. We examined the nature of DW, the mechanism for SC, and analyzed the relationship between DW and SC from both theoretical and experimental results reported so far. In addition, similarities and differences between titanium-based pnictide oxides and cuprates/iron-based superconductors are discussed in terms of crystal structure, physical property, and band topology.
