deltaihases
Deltaihases are a term used in theoretical studies to describe transient or metastable states produced by delta-like perturbations in dynamical systems. The concept sits at the intersection of phase-transition theory and impulse-response analysis, referring to states that resemble phases but arise from abrupt inputs rather than gradual parameter changes.
Etymology: the name combines delta, denoting a sudden change or impulse, with phase, reflecting a state of
Characteristics: deltaihases are typically rapid to onset and short-lived, with configurations that differ qualitatively from neighboring
Occurrence: the idea appears in models of impulsive control, electrical networks with kick-like injections, materials under
Relationship to conventional phases: deltaihases are not equilibrium phases; they are perturbation-induced transients that can bridge
