Unconventional topological phase transition of the Hopf insulator
Sunje Kim, Ysun Choi, Hyeongmuk Lim +1
The topological phase transition between two band insulators is mediated by a gapless state whose low-energy band structure normally contains sufficient information for describing…

Linking structures of doubly charged nodal surfaces in centrosymmetric superconductors
Sunje Kim, Dong-Choon Ryu, Bohm-Jung Yang
In topological semimetals and nodal superconductors, band crossings between occupied and unoccupied bands form stable nodal points/lines/surfaces carrying quantized topological cha…
