Topological Axion States in the Magnetic Insulator with the Quantized Magnetoelectric Effect
D Zhang, M Shi, T Zhu, D **, and chiral hinge states in crystalline insulators
We extend the theory of dipole moments in crystalline insulators to higher multipole
moments. As first formulated in Benalcazar et al.[Science 357, 61 (2017) SCIEAS 0036-8075 …
