Cross-domain structural pattern
Local ergodicity in subsystems, rather than global ergodicity, enables thermalization. Subsystem dynamics appear pseudorandom due to local interactions. Statistical properties of observables emerge from this effective local randomization without requiring the entire system to be ergodic.
view paper→Qualitative phase transition via spectral condensation at criticality. Progressive reentrant coupling drives system toward infrared critical regime where extensive band of slow collective modes emerges (spectral condensation), reorganizing dynamics qualitatively. Creates emergent capabilities absent at subcritical regime - transition in kind not degree, regardless of system scale.
