A moiré pattern appears when you stack and rotate two copies of an image with regularly repeating shapes, turning simple patterns of squares or triangles into a groovy wave pattern that moves across ...

Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These ...

Phasons, low-temperature quasiparticles found in crystal lattices, help interlayer excitons move at ultra-low temperatures, offering insights for materials science and potential boosts to quantum tech ...
