Electronically polarized systems are physical systems in which the electronic charge distribution is displaced relative to the nuclei, producing a net electric polarization that can be static, induced, or dynamic. This polarization arises from external electric fields, internal crystal fields, broken inversion symmetry, interfaces, or collective electronic instabilities, and is described microscopically by changes in electronic wavefunctions and macroscopically by a polarization vector field. Such systems include dielectrics, ferroelectrics, polar semiconductors, and heterostructures where bound or itinerant electrons respond anisotropically, strongly influencing dielectric response, excitations, screening, charge transport, and nonlinear optical properties central to condensed-matter and materials physics.
With the rapid spread of cloud computing, artificial intelligence and data centers, global energy consumption is rising to new heights. A promising way to reduce this burden is to develop memory devices that store information ...
