Topological Kerr effects in two-dimensional magnets with broken inversion symmetry
The whorls of localized moments in chiral magnetic structures, such as skyrmions, lead to a quantized topological charge, which may make them useful as next-generation information bits. So far, the most reliab...

A new C=C embedded porphyrin sheet with superior oxygen reduction performance
C2 is a well-known pseudo-oxygen unit with an electron affinity of 3.4 eV. We show that it can exhibit metal-ion like behavior when embedded in a porphyrin sheet and form a metal-free two-dimensional material wi....
