Refined symmetry indicators for topological superconductors in all space groups
Seishiro Ono, Hoi Chun Po, Haruki Watanabe
Topological superconductors are exotic phases of matter featuring robust surface states that could be leveraged for topological quantum computation. A useful guiding principle for…
Geometric orbital magnetization in adiabatic processes
Luka Trifunovic, Seishiro Ono, Haruki Watanabe
We consider periodic adiabatic processes of gapped many-body spinless electrons. We find an additional contribution to the orbital magnetization due to the adiabatic time evolution…
Difficulties in operator-based formulation of the bulk quadrupole moment
Seishiro Ono, Luka Trifunovic, Haruki Watanabe
Electric multipole moments are the most fundamental properties of insulating materials. However, the general formulation of bulk multipoles has been a long standing problem. The so…
Symmetry indicators for topological superconductors
Seishiro Ono, Youichi Yanase, Haruki Watanabe
The systematic diagnosis of band topology enabled by the method of "symmetry indicators" underlies the recent advances in the search for new materials realizing topological crystal…
