반응형 Market Physics (시장 물리학)19 1966 Kubo Paper Review: Why History Matters in the Generalized Langevin Equation and Memory Kernels. 요약 및 제언 본 글은 Ryogo Kubo의 1966년 논문 "The fluctuation-dissipation theorem"을 기반으로, 기억 커널(Memory Kernel)을 포함한 일반화된 랑주뱅 방정식(GLE)의 물리적 의미와 그 응용을 심층 분석했습니다. 고전적인 백색 잡음(White Noise) 가정의 한계를 지적하고, 시스템의 과거 이력이 현재의 저항(마찰)에 미치는 영향을 수학적으로 규명했습니다. 특히 요동-산일 정리(FDT)가 미시적 요동과 거시적 산일 과정을 어떻게 연결하는지, 그리고 이것이 비마르코프(Non-Markovian) 시스템 해석에 어떤 통찰을 제공하는지를 재해석했습니다. Discover the profound link between thermal.. 2026. 1. 25. Decoding Einstein (1905): The Physics Behind the Black-Scholes Model Key Insight: 5. Einstein Brownian Motion Diffusion Coefficient. This post dissects Einstein's 1905 paper to reveal the true origin of market volatility models and why blind reliance on the square root of time rule creates "fake volatility." To be honest, looking at the modern financial markets recently, I have often felt a sense of stifling suffocation. We are bombarded with news .. 2026. 1. 23. Are We Living on a Sandpile? SOC Theory and Systemic Risk Key TakeawayWhy do markets crash and sandpiles collapse? We dive deep into the seminal 1987 paper by Bak, Tang, and Wiesenfeld to uncover the secret of "Self-Organized Criticality." This is the physics of how stability creates instability.We live in a world that craves stability. We build systems, portfolios, and lives hoping they will remain standing forever. But have you ever felt that the saf.. 2026. 1. 21. Robert Zwanzig: How to Thaw a Frozen Market (Glass Transition) Core Takeaway We conduct an in-depth analysis of quantitative strategies to navigate the market's liquidity trap through the lens of Robert Zwanzig's Nonequilibrium Statistical Mechanics. We aim to read macroscopic flows from microscopic movements, sense the market's temperature beyond complex equations, and seek the wisdom to transform crises into opportunities. We ar.. 2026. 1. 19. Why Glass Never Relaxes: Parisi, RSB, and Effective Temperature 'Replica Symmetry Breaking & Effective Temperature' Why does a glass never truly relax? Discover the deep connection between Giorgio Parisi's Replica Symmetry Breaking (RSB), the hierarchical structure of complex landscapes, and the Cugliandolo-Kurchan concept of Effective Temperature. This is the alpha you need to understand complexity.Let’s be honest. Most people think "disorder" just means a .. 2026. 1. 13. Fat Tails and Lévy Distributions: How Normal Distributions Ruin Your Account The Dangerous Liaison Between Physics and FinanceWe seek order within the chaos of the market through the 'Spin Glass Theory,' the bible of complex systems physics, and 'Econophysics,' which interprets financial markets through science. We dive deep into how Parisi's theory might just be what saves your portfolio.To be honest, the stock market charts we look at every day often feel like pure cha.. 2026. 1. 11. 이전 1 2 3 4 다음 반응형
