lisions

Lisions are a hypothetical phenomenon in the realm of physics and related disciplines. The term refers to localized, transient exchanges of energy that occur when two oscillating fields or wave packets overlap in space and time, without necessarily resulting in a macroscopic collision or transfer of matter. In the concept's original formulations, lisions are characterized by brief modifications to phase and amplitude within a confined region.

Mechanism: When two coherent field configurations intersect, their superposition can lead to interference patterns whose local energy density temporarily deviates from the sum of the individual fields. Depending on the model, a lision may be elastic, restoring the original states after the interaction, or inelastic, leaving residual excitations in the medium. The duration of a lision is typically short, governed by the overlap time of the interacting structures and the properties of the medium.

Classification: Lisions can be categorized by the type of field involved (electromagnetic, acoustic, matter waves) and by outcome (elastic vs. inelastic; constructive vs. destructive). Some proposals distinguish sign- and amplitude-based lisions to describe the direction of induced energy flow.

Detection and evidence: In simulations, lisions appear as brief localized perturbations in field amplitudes. In experimental thought experiments, observers look for transient phase shifts and energy redistribution in tightly confined regions. There is no consensus on observable criteria, and most discussions remain theoretical or fictional.

Applications and relation: The concept is sometimes used in science fiction and theoretical explorations as a convenient shorthand for short-range interactions without mass transport. See also: interference, collision, soliton.
