excitationssuch

Excitationssuch is a term encountered in some interdisciplinary discussions to denote the systematic search for excited states and their properties in a physical system. It is not a standardized term in physics or chemistry, and its usage varies by author. In practice, it can be understood as a workflow or methodological stance focusing on identifying, classifying, and understanding excitations such as electronic, vibrational, magnetic, or polaritonic modes.

The term can be seen as a compound of "excitations" and the phrase "such as" in some bilingual discussions, or as a portmanteau in other contexts. Because it is not widely codified, definitions differ and it often appears in introductory or speculative discussions rather than in formal manuals.

Conceptually, excitationssuch emphasizes the processes that generate and detect excitations, including experimental techniques (time-resolved spectroscopy, pump-probe, inelastic scattering) and theoretical tools (quantum chemistry, many-body perturbation theory, lattice dynamics). The goal is to map the landscape of accessible excitations and to understand their lifetimes, couplings, and roles in material properties.

Applications include the study of photovoltaic materials, light-emitting devices, quantum materials, and chemical reaction dynamics, where excited states play a central role. Challenges include transient lifetimes, many-body effects, and the need for integrated experimental and computational approaches.
