In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to ...

An international collaborative research group has developed a new computational method to visualize the electronic states of aperiodic nanomaterials as band structures through first-principles ...

How atoms acquire three-dimensional bulk character is one of the fundamental questions in materials science. Before addressing this question, how atomic layers become a bulk crystal might give a hint ...

Many complex magnetic structures in a high-symmetry lattice can arise from a superposition of well-defined magnetic wave vectors. These “multi-q” structures have garnered much attention because of ...

Bandgap refers to a region of an element’s crystal’s electronic band structure through which electrons can’t pass. Also referred to as an energy gap, bandgap is a concept in solid-state physics and ...
