Econophysics

Econophysics applies the statistical mechanics and complexity tools of theoretical physics to financial markets and economic systems. Rather than assuming rational equilibrium, researchers treat markets as out-of-equilibrium many-body systems exhibiting power-law distributions, phase transitions, and avalanche dynamics. The discipline originated in the mid-1990s when physicists noticed that the fat-tailed return distributions and volatility clustering of stock prices looked uncannily like critical phenomena in condensed matter. Key deliverables include early-warning signals for market crashes, entropy-based portfolio risk measures, and network models of systemic banking contagion. Hedge funds and central banks are the primary industry draws, and the typical practitioner holds a physics PhD but publishes in both physics and economics journals.
