— Gray Zone Operations Simulation in U.S.-China Competition (2025–2027)

---

Introduction

This report applies the framework of Quantum Field Theory (QFT) to simulate the roles and potential scenarios of Pacific island chain countries (including Taiwan, Japan, the Philippines, South Korea, Guam, and Australia) in the geopolitical competition between the U.S. and China from 2025 to 2027, with particular focus on China’s gray zone operations targeting Taiwan. Originally a tool from physics used to describe particle interactions, QFT has in recent years been adapted to social sciences, offering new perspectives for analyzing complex systems. In this report, each nation is conceptualized as a “field,” and mathematical equations and visualizations are used to model the dynamics of influence, anchored to a time-stamped reference point (May 23, 2025) to ensure alignment with current realities. While this interdisciplinary method is innovative, its predictions should be interpreted with caution due to the complexity of real-world events and data limitations.

Background and Related Research

Quantum Field Theory (QFT) combines quantum mechanics and relativity to describe particle behavior. Concepts such as entanglement and superposition have recently been applied to economics, psychology, and international relations. For example, Quantum Social Science (Wikipedia, accessed May 23, 2025) notes the “quantum turn” in the social sciences around 2018, showing quantum thinking's influence on diplomatic studies. Alexander Wendt’s Quantum Mind and Social Science (2015) discusses the applicability of quantum theory to social systems, while Quantum Field Theory for Economics and Finance (Cambridge University Press Blog, 2018) demonstrates QFT’s potential for modeling complex economic systems. Danah Zohar (2018) also advocates for quantum perspectives in addressing global issues, indirectly supporting their application to geopolitics.

This report is based on publicly available information as of May 23, 2025 (e.g., CSIS Taiwan war game simulations, military and economic trend data), assuming continued geopolitical trends (U.S.-China tensions, island chain alliance dynamics). Time verification points include short-term (H2 2025), medium-term (2026), and long-term (2027) forecasts to ensure model–reality alignment.

Model Design: Nations as “Fields”

We abstract the geopolitical environment as a “field,” where each country is an energy source emitting military, economic, diplomatic, and informational influence, interacting through attraction or repulsion to shape actions and outcomes.

1. Field Definitions

• U.S. Field (φ_A(x)):

  • Military: Aircraft carriers, Guam bases

  • Economic: U.S. dollar dominance, CHIPS Act

  • Diplomatic: U.S.-Japan-Korea alliance, AUKUS

  • Information: Anti-TikTok legislation, media coalitions

• China Field (φ_C(x)):

  • Military: Navy, missile forces

  • Economic: Belt and Road Initiative (BRI), ASEAN trade

  • Diplomatic: Shanghai Cooperation Organization, coordination with Russia

  • Information: TikTok, AI-driven cognitive warfare

• Island Chain Country Fields (φ_I(x)):

  • I includes Taiwan, Japan, the Philippines, South Korea, Guam, Australia — each field reflects national defense, economy, and political orientation

Field Strength Calculation:

Φ(Country, t) = α × Military + β × Economy + γ × Diplomacy + δ × Information

• α, β, γ, δ: Weights representing importance (e.g., α = 0.4 for military, β = 0.3 for economy)

• x: Spacetime coordinates (2025–2027, Pacific Island Chain)

Field Interaction:

F(A→B) = k × [Φ(A) × Φ(B)] / d²

• k: Coupling constant (e.g., k_AC = 0.5 for U.S.–China rivalry)

• d: Geographical/cultural distance (e.g., Taiwan–China distance is low → strong interaction)

---

2. Field Equations

The system is described by the Lagrangian density L:

• Free Field (domestic dynamics):

L_free = Σ_k=A,C,I [½(∂_μ φ_k)² − ½ m_k² φ_k²]

• ∂_μ: Temporal/spatial derivative

• m_k: Field "mass," representing resistance to change (e.g., U.S. has high m_A due to global stability)

• Interaction Field (inter-country influence):

L_int = −k_AC φ_A φ_C − Σ_I k_AI φ_A φ_I − Σ_I k_CI φ_C φ_I

• Equation of Motion:

□ φ_I + m_I² φ_I = k_AI φ_A − k_CI φ_C

Where □ = ∂_μ ∂^μ, representing the influence on island countries from U.S. support (k_AI φ_A) and Chinese pressure (k_CI φ_C)

3. Baseline Data: May 23, 2025

3.1 U.S.–China Field Characteristics

• China:

  • Military: Normalized patrols to the third island chain, 2–3 Taiwan drills/month

  • Economy: BRI at investment peak, 35% of trade with ASEAN

  • Diplomacy: Expanded SCO, new energy agreements with Russia

  • Information: Over 2 billion TikTok users, enhanced AI deepfake warfare

• United States:

  • Economy: Friend-shoring policies in effect, CHIPS Act reshapes supply chain

  • Diplomacy: Strengthened QUAD, new U.S.-Philippines base agreement

  • Information: Anti-TikTok law passed, enhanced democratic media collaboration

3.2 Island Chain Field Alignment

• First Island Chain:

  • Taiwan: High but unstable field strength, domestic political division (2025 poll: 37.5% believe U.S. will intervene)

  • Japan: Core U.S. ally, accelerating military normalization

  • Philippines: Shifting toward U.S., South China Sea tensions rising

  • South Korea: Balancing U.S.–China, focused on North Korea

• Second Island Chain:

  • Guam: Stable upward trend, key U.S. military hub

  • Australia: Deep AUKUS involvement, clear anti-China stance

• Third Island Chain:

  • Hawaii: U.S. Pacific Command HQ, strategic value unchanged

Simulation: China’s Gray Zone Operations Against Taiwan

Assumption: From 2025–2027, China employs gray zone strategies (actions between peace and war) to weaken Taiwan through military pressure, economic inducement, information warfare, and diplomatic isolation.

---

4. Field Model for Gray Zone Operations

Gray Zone Equation (as interference term):

ΔΨ_gray(t) = η_M·ψ_M(t) + η_E·ψ_E(t) + η_I·ψ_I(t) + η_D·ψ_D(t)

• ψ_M(t): Military coercion field (e.g., 2–3 air incursions per month, reduced to median line by 2026)

• ψ_E(t): Economic manipulation (e.g., selective openness to Taiwanese business, internal fragmentation)

• ψ_I(t): Information ops (e.g., AI deepfakes influence opinion, +20% misinformation in 2025)

• ψ_D(t): Diplomatic isolation (e.g., increased frequency of blocking Taiwan from international orgs)

• η: Efficiency coefficients for each action, time-dependent

Counter-Equation:

Ψ_counter(t) = f[Intelligence Sharing, Military Deterrence, Economic Sanctions, Diplomatic Support]

• U.S.: Arms sales (e.g., anti-ship missiles), intelligence sharing

• Japan: 30% increase in joint drills, logistics support

• Philippines: Base cooperation, low-profile stance

• South Korea: Intelligence sharing, limited involvement

5. Charts and Visualization

The following bar charts show national influence dynamics from 2025–2027, based on gray zone scenario assumptions and the May 23, 2025 baseline data.

Chart Analysis

United States (Blue): 2025 influence at 7, slightly reduced by domestic politics (new administration's "America First" policies); increases to 8 by 2026-2027 due to military deployments (AUKUS nuclear submarines, Guam upgrades).

China (Red): 2025 influence at 8, leveraging naval scale (360 vessels) and economic pressure; reaches 9 by 2027 through military modernization.

Taiwan (Green): 2025 influence at 5, affected by China's gray zone pressure (trade restrictions), drops to 4.5 in 2026; recovers to 5.5 in 2027 with enhanced US support.

Japan (Yellow): 2025 influence at 6, constrained by pacifist constitution and economic dependence on China; gradually increases to 6.5 by 2026-2027 through US-Japan alliance strengthening.

Philippines (Purple): 2025 influence at 4, maintains low profile due to weak military capabilities and economic dependence on China; slight increase to 4.2 by 2027 (US-Philippines alliance support).

South Korea (Orange): 2025 influence at 5.5, focused on Korean Peninsula with limited Taiwan Strait involvement; slight increase to 5.7 by 2027 (stable US-ROK alliance).

Temporal Validation: Based on May 23, 2025 baseline, assuming no major conflicts (public reports show no Taiwan Strait war), China employs gray zone strategies. Data reflects quantum field theory model from the report: Chinese pressure (g_CI φ_C) intensifies annually, while US and allied support (g_AI φ_A) attempts to maintain balance.

Conclusion

This report uses quantum field theory to conceptualize China, the U.S., and First Island Chain countries as interacting “fields,” simulating geopolitical dynamics from 2025 to 2027, especially focusing on China's gray-zone operations toward Taiwan. Using equations (e.g., Φ = α × Military + β × Economy), visualizations, and timeline-based validation (baseline: May 23, 2025), the model provides a testable predictive framework. Despite the complexity of real-world events and data limitations, this approach opens a new path that integrates science with strategic intuition for decision-making and academic research. In the future, it can be further enhanced by incorporating real-time data streams and coupling with AI models, leading to a cross-disciplinary “predictive field computation” system.

Quantum Field Equations and Country-Specific Models

1. United States Field Ψ_US

• Equation:
  Ψ_US = α₁ × Military + β₁ × Economic + γ₁ × Diplomatic + δ₁ × Domestic
  (Interaction term with Taiwan: λ × Ψ_US × Φ_TW)

• Interpretation:
  The U.S. exhibits strong inertia in security field momentum but displays high volatility in the domestic political field.
  In this model, Ψ_US affects Taiwan’s field intensity through the coupling term λ × Ψ_US × Φ_TW.

---

2. China Field Ψ_CN

• Equation:
  Ψ_CN = α₂ × Military + β₂ × Economic + γ₂ × Diplomatic + ε₂ × Nationalism
  (Interaction term with Taiwan: κ × Ψ_CN × Φ_TW)

• Interpretation:
  China’s field is characterized by centralized action and strong long-range projection capability.
  It influences Taiwan through the κ × Ψ_CN × Φ_TW coupling term, with gray-zone pressure being a non-linear component.

---

3. Taiwan Field Φ_TW

• Equation:
  Φ_TW = μ × National Defense + ν × Resilience + ξ × International Support
  (Interaction terms: λ × Ψ_US × Φ_TW + κ × Ψ_CN × Φ_TW)

• Interpretation:
  Taiwan’s field is sensitive to external coupling.
  A key indicator is its internal coherence and responsiveness under pressure.

---

4. Japan, Philippines, Australia (Allies) Fields Φ_JP, Φ_PH, Φ_AU

• Equations:
  Φ_i = σ × Bilateral Alliance + τ × Regional Engagement
  (i = JP, PH, AU; interaction with Ψ_US via strategic coherence)

• Interpretation:
  These states act as subfields within the Indo-Pacific structure, enhancing collective field strength through resonance.
  Their coherence depends on U.S. field frequency and phase matching.

---

5. ASEAN Composite Field Φ_ASEAN

• Equation:
  Φ_ASEAN = θ × Economic Gravity + ω × Strategic Ambiguity – χ × External Pressure

• Interpretation:
  The ASEAN field shows collective inertia and resistance to polarization.
  Its alignment depends on the balance of economic gravity (toward China) and security concern (toward the U.S.).

Spatiotemporal Simulation Design

• Time Axis:
  May 2025 – December 2027 (30-month frame)

• Field Interaction Map:

  • Ψ_CN and Ψ_US exert long-range pressure on Φ_TW

  • Φ_JP and Φ_PH form stabilizing subfields

  • Φ_ASEAN fluctuates near a local equilibrium

• Potential Function V(Φ):
  The Taiwan Strait potential resembles a double-well structure:
  one stable basin for "peaceful ambiguity" and another for "escalatory bifurcation."

---

Vacuum Expectation Value (VEV) and Stability Criteria

• VEV Definition:
  ⟨Φ_TW⟩ = average field state under low-pressure conditions

• Stability Condition:
  d²V/dΦ² > 0 at ⟨Φ_TW⟩ ensures local minimum
  If perturbations (ΔΨ_CN or ΔΨ_US) exceed critical threshold, symmetry breaking may occur.
