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 ...

In the left two figures, the isolated band can be formed through increasing the orbital energy difference or decreasing the orbital overlap between M and X elements. In the right, according to this ...

Quantum materials, defined by their photon-like electrons, are opening new frontiers in material science. Researchers have synthesized organic compounds that display a universal magnetic behavior tied ...

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 ...
