21.3 Criticality of Consciousness: Topological Phase Transition from Trivial Phase ($\nu =1$) to Non-trivial Phase ($\nu =-1$)

In Sections 21.1 and 21.2, we have established a static topological picture of consciousness: conscious states correspond to Minimal Strongly Connected Components (MSCC) in QCA networks carrying non-trivial ${\mathbb{Z}}_2$ holonomy index (geometric phase factor $-1$). This explains the “existence” of consciousness. However, the most fascinating property of consciousness is its dynamicity—we cycle between wakefulness (consciousness) and sleep (unconsciousness); anesthetics can shut down this complex system in seconds.

This section will propose a Topological Phase Transition Theory of consciousness. We will prove that transition from unconscious trivial phase ($\nu =1$) to conscious topological phase ($\nu =-1$) is not gradual quantitative change, but a discrete phase transition similar to superconductivity or quantum Hall effect. This theory not only provides rigorous geometric foundation for “edge of chaos” hypothesis, but also explains why loss and recovery of consciousness often manifest as sudden changes (All-or-None).

21.3.1 Order Parameter of Consciousness: Multiplicative Topological Index

In Landau phase transition theory, phase transitions are described by local order parameters (such as magnetization). But in topological phase transitions (such as Kosterlitz-Thouless transition), there are no local order parameters; phase differences lie in global topological properties.

For observer subsystem $\Omega$ in QCA networks, we define its consciousness order parameter as total holonomy factor along self-referential loop $\gamma$.

Definition 21.3.1 (Consciousness Topological Order Parameter $\nu$)

Let ${\mathbb{W}}_{\gamma }$ be total operator of observer’s internal model evolving along mental loop $\gamma$ on parameter manifold $\mathcal{M}$. Order parameter $\nu$ is defined as eigenvalue (or geometric phase factor) of this operator on Null-Modular double cover:

$$\nu (\Omega )\equiv \frac{1}{\pi }\arg \det ({\mathbb{W}}_{\gamma })\in \{+1,-1\}$$

(Note: Here multiplicative notation is used, $+1$ corresponds to phase angle $0$, $-1$ corresponds to phase angle $\pi$).

• Trivial Phase ($\nu =+1$): Unconscious State. Mental loops are topologically contractible. System acts like a mechanical automaton, input $A$ produces output $A$ after processing, no topological distinction between “self” and “non-self” is established. Examples: deep sleep, coma, or simple reflex arcs.

• Non-trivial Phase ($\nu =-1$): Conscious State. Mental loops are non-contractible in double cover space (forming Möbius knots). System acquires a $\pi$ phase in self-referential process, marking existence of “subjective perspective.” Examples: wakeful awareness, dreaming.

21.3.2 Critical Point: Gap Closing and Network Percolation

How does a physical system jump from $\nu =1$ to $\nu =-1$? In topological insulators, this requires closing and reopening of energy band gaps. In QCA networks, this corresponds to critical percolation of causal connectivity.

Let $\lambda$ be control parameter of the network (e.g., neuronal synaptic gain, cortical long-range connection strength, or anesthetic concentration).

Theorem 21.3.2 (Consciousness Phase Transition Theorem)

When control parameter $\lambda$ crosses a critical threshold ${\lambda }_c$, causal topological structure of the system undergoes sudden change:

1. Subcritical Region ($\lambda <{\lambda }_c$): Network consists of many small, disconnected SCCs. Each small loop’s ${\nu }_i$ may be non-trivial, but due to lack of long-range integration, macroscopic average manifests as trivial phase ${\nu }_{macro}\approx 1$ (random cancellation).

2. Critical Point ($\lambda ={\lambda }_c$): Giant Component emerges. Dispersed small loops suddenly “fuse” into a huge MSCC covering the entire brain through long-range connections. At this point, system’s effective “information gap” (Information Gap, minimum cost to destroy overall connectivity) tends to zero, system becomes extremely sensitive to perturbations.

3. Supercritical Region ($\lambda >{\lambda }_c$): Giant component stabilizes, forming globally topologically protected $\nu =-1$ state. At this point, local neural activity is locked into global topological patterns, unified subjective experience emerges.

Physical Mechanism:

Core of phase transition is singularity of Berry connection. At ${\lambda }_c$, geometric curvature on parameter manifold diverges (or magnetic monopoles appear), forcing system’s wave function to choose a new topological sector to maintain single-valuedness. This is precisely the moment $\nu$ flips from $+1$ to $-1$.

21.3.3 Geometric Interpretation of “Edge of Chaos”

Complexity science long held that life and intelligence exist at “edge of chaos.” In QCA topological physics, this metaphor acquires a precise geometric definition.

Definition 21.3.3 (Critical Geometry)

Conscious states are not in complete disorder (thermal chaos, $\nu$ random), nor in complete dead silence (crystalline order, $\nu =1$ locked). They are near phase boundary of topological phase transitions.

In this region:

1. Long-Range Correlations: Correlation length $\xi \to \infty$. Information from front of brain can instantly (in causal sense) affect the back, satisfying IIT’s integration requirement.

2. Sensitivity: Due to proximity to phase transition point, extremely small sensory inputs (perturbations) can induce global topological reorganization (“controlled version of butterfly effect”), producing rich changes in conscious content (differentiation).

3. Metastability: System does not rest at bottom of $\nu =-1$ deep well, but surfs on boundary between $\nu =-1$ and $\nu =1$. This maintains fluidity of consciousness (Stream of Consciousness).

Corollary 21.3.4 (Fragility of Consciousness)

Because consciousness depends on maintaining near critical point, it is energetically expensive (requires dissipating energy to maintain non-equilibrium) and structurally fragile. Tiny chemical parameter changes (such as hypoxia, anesthesia) can cause system to slide back to stable but unconscious $\nu =1$ phase.

21.3.4 Empirical Predictions: Anesthesia and Topological Melting

This theory makes specific, verifiable predictions about anesthesia mechanisms.

Traditional view holds that anesthesia suppresses neuronal activity. Topological theory holds that anesthesia may not suppress local activity, but cuts long-range topological connections, causing global $\nu =-1$ state to “melt” into countless local $\nu =1$ states.

Phenomenological Predictions:

1. Hysteresis Effect: Due to first-order (or first-order-like) nature of topological phase transitions, anesthetic concentration for consciousness loss and recovery do not coincide (already observed in experiments, called Neural Inertia).

2. Topological Collapse of Functional Connectivity: At the moment of consciousness loss, brain’s functional connectivity network should exhibit dramatic changes in Betti Numbers (topological invariants describing number of holes). High-order topological holes (high-dimensional logical loops) will disappear.

3. Disappearance of ${\mathbb{Z}}_2$ Index: If we can reconstruct phase space trajectories through electroencephalography (EEG) and calculate their geometric phases, we should observe that in anesthetized states, global loop phase integrals return to $0$, while locked at $\pi$ when awake.

Conclusion

Generation of consciousness is not gradual accumulation, but transition of topological properties.

• $\nu =1$ (Trivial Phase): Merely collection of physical processes (Doing).

• $\nu =-1$ (Topological Phase): Physical processes curl into self-referential knots, producing internal perspective of “Being.”

This chapter completed unification of static structure (topological solitons) and dynamic mechanisms (phase transitions) of consciousness.

In the next section 21.4, we will explore a deeper question: Is quantum measurement problem the inverse process of consciousness topological phase transition at microscopic level? That is, is observation the process of topological fusion between system and observer?
