Hidden Moir'e Topology of Low-Symmetry Weyl Surfaces
The study investigates how low-symmetry surfaces, like NdAlSi's (103) facet, create a hidden moiré pattern that links bulk and surface states. By using a Least Common Multiple (LCM) framework, the authors show this mismatch is not a failure of physics but rather due to incomplete bulk projection. This reveals momentum-space moiré as the key mechanism governing boundary states.
