Fermi lune and non-reciprocal transport in rhombohedral multilayer graphene
Researchers discovered a new bulk Fermi surface structure called the "Fermi lune" in rhombohedral multilayer graphene. This structure spontaneously breaks fundamental symmetries, leading to giant intrinsic non-reciprocal transport and a new magnetic state called "transdimensional orbital magnetism." This finding offers insights into novel electronic phenomena in materials exhibiting low symmetry.
