A new unified framework merges Lie algebra with the Foldy-Wouthuysen transformation to quantify "catability"—a measure of quantum superposition coherence—in relativistic systems of any spin, addressing long-standing challenges in relativistic quantum mechanics. The study introduces a phase-sensitive catability operator, enabling precise analysis of quantum interference and coherence effects in relativistic dynamics, particularly for high-energy states where traditional methods fail. Applied to Dirac spin-½ particles, the framework reveals how spinorial structures and symmetry generators influence fermionic catability, offering insights into relativistic quantum behavior beyond classical limits. The generalized approach extends to arbitrary spin-s fields, providing a consistent algebraic structure to study higher-spin relativistic states, unifying fermionic and bosonic systems under one theoretical umbrella. This work establishes a foundational platform for exploring relativistic quantum coherence, superposition, and algebraic symmetries, with potential applications in quantum field theory and high-energy physics.

Quantum Physics arXiv:2605.08248 (quant-ph) [Submitted on 7 May 2026] Title:Generalized Catability of Relativistic Quantum States Measurement in a Unified Lie-Algebraic Foldy-Wouthuysen (FW) Framework Authors:Abdelmalek Bouzenada View a PDF of the paper titled Generalized Catability of Relativistic Quantum States Measurement in a Unified Lie-Algebraic Foldy-Wouthuysen (FW) Framework, by Abdelmalek Bouzenada View PDF HTML (experimental) Abstract:In this work, a unified Lie-algebraic formulation of catability is constructed for relativistic quantum systems with arbitrary spin within this framework. In this case, the analysis starts with constructing catability as a quantitative measure for superposed coherent states, where coherence structure and quantum interference properties are studied using algebraic representations in this framework. Also, a generalized Foldy-Wouthuysen transformation is formulated within a Lie algebraic framework, delivering a systematic procedure for block-diagonalization of relativistic Hamiltonians and separation of positive- and negative-energy components in this framework. Within this formalism, a phase-sensitive catability operator is introduced to study phase correlations and coherence effects in the relativistic quantum dynamics framework. The approach is applied to Dirac spin-$1/2$ particles, where relativistic fermionic catability is analyzed in relation to spinorial structures and symmetry generators framework. The formalism is extended through a unified geometric and Lie-algebraic treatment, establishing a consistent description of catability in a relativistic quantum mechanics framework. In this context, the generalized framework is constructed for arbitrary spin-$s$ fields, enabling investigation of higher-spin relativistic quantum states within the same algebraic structure framework. In this context, the obtained results show a generalized theoretical platform for investigating relativistic quantum coherence, superposition effects, and algebraic symmetries in the framework of fermionic and bosonic systems.
