- We propose a dynamical reinterpretation of axion misalignment as an emergent collective phenomenon. Drawing an explicit parallel between axion field dynamics and synchronization in coupled oscillator systems, we show that a macroscopic axion phase can arise dynamically from initially incoherent configurations through gradient-driven ordering in an expanding Universe. In this framework, the misalignment angle is not a fundamental initial condition but a collective variable that becomes well defined only once phase coherence develops. Using a simple lattice model, we illustrate how the collective phase is selected prior to the onset of axion oscillations, providing a dynamical basis for the standard misalignment picture. This perspective offers a new way of organizing axion initial-condition sensitivity, reframes anthropic small-angle arguments in terms of phase-ordering efficiency, and suggests a broader connection between fine-tuning and emergent collective dynamics in the early Universe.
