Sixfold excitations in electrides

In high-energy physics, PoincarĂ© symmetry puts strong constraints on the standard model, leading to only three different types of fermions, i.e., Dirac, Weyl, and Majorana fermions. Although several kinds of particles (such as protons) are confirmed to be Dirac fermions, the signature of Weyl and Majorana fermions is still lacking in particle physics experiments. In […]

Opportunities and Challenges in Twisted Bilayer Graphene: A Review

Two-dimensional (2D) materials exhibit enhanced physical, chemical, electronic, and optical properties when compared to those of bulk materials. Graphene demands significant attention due to its superior physical and electronic characteristics among different types of 2D materials. The bilayer graphene is fabricated by the stacking of the two monolayers of graphene. The twisted bilayer graphene (tBLG) […]
