Charge density wave

ID: charge-density-wave

A charge density wave (CDW) is a phenomenon observed in some materials, particularly in low-dimensional systems, where the electronic charge density becomes modulated in a periodic manner. This modulation effectively induces a spatial structure in the distribution of charge carriers, leading to regions of higher and lower charge density over specific distances. CDWs are often associated with materials that exhibit strong electron-electron interactions and can result in collective state behaviors, similar to those seen in other ordered phases such as superconductivity or magnetism.
