Fysischionisch

Fysischionisch is a proposed interdisciplinary framework in the physical sciences that centers on the role of ions in determining the properties and behavior of physical systems. Proponents envision a synthesis of solid-state physics, electrochemistry, and plasma science in which ions are treated as active agents—not only as charge carriers but as drivers of transport, polarization, and phase phenomena. This approach emphasizes the coupling between ionic motion, lattice dynamics, electronic structure, and external fields, applying across solids, ionic liquids, interfaces, and plasmas.

Origin and status: The term appears in a small body of theoretical discussions and conference papers, and its use is not standardized. It is not an established discipline, nor is there a unified methodology or governing body. In practice, researchers working on related topics often operate within traditional fields such as solid-state physics, electrochemistry, or ionics, sometimes using an ion-centric vocabulary without adopting a separate label.

Methods and questions: Work associated with fysischionisch would rely on first-principles calculations (quantum chemistry, density functional theory), molecular dynamics, and advanced spectroscopy, alongside experimental techniques like impedance spectroscopy, neutron and X-ray scattering, and ultrafast measurements. Major questions include how ionic ordering and transport couple to phase transitions, how ions influence electronic and phononic spectra, and how interfaces mediate ion-driven phenomena in energy storage, sensors, and plasmas.

Relation to existing fields: Fysischionisch overlaps with solid-state physics, electrochemistry, ionic liquids research, and plasma physics. Critics argue that the term offers limited practical value unless it provides a clear theoretical framework or predictive power distinct from established disciplines. As of now, fysischionisch remains a niche or exploratory label rather than a formal field.
