Topological classification under nonmagnetic and magnetic point group symmetry: Application of real-space Atiyah-Hirzebruch spectral sequence to higher-order topology
Nobuyuki Okuma, Masatoshi Sato, Ken Shiozaki
We classify time-reversal breaking (class A) spinful topological crystalline insulators with crystallographic non-magnetic (32 types) and magnetic (58 types) point groups. The clas…

Nonreciprocal superposition state in antiferromagnetic optospintronics
Nobuyuki Okuma
The absence of net magnetization, which forbids any stray magnetic fields, is one of the greatest advantages of antiferromagnets in device applications. In conventional antiferroma…
