The laboratory develops theoretical tools for calculating polymer nanostructures since 2009. It focuses on predicting and analyzing experimental results. The lab has conducted research using Self-Consistent Field Theory (SCFT) to calculate the statistical physics properties of polymers using mean-field theory. Currently, it focuses on developing and applying Langevin Field-Theoretic Simulation (L-FTS), a more precise simulation tool that includes fluctuation effects. The lab applies deep learning techniques to analyze soft materials and accelerate simulations and welcomes students interested in traditional statistical physics, deep learning, and AI.

본 연구실에서는 2009년부터 고분자 나노구조 계산에 필요한 다양한 이론적 도구를 개발하고 실험 결과 예측 및 분석을 통해 연구를 수행한다. 고분자의 통계물리학적 성질을 평균장 이론으로 계산하는 자체일관 장이론(SCFT)을 이용한 연구를 수행해 왔으며, 최근에는 요동 효과를 포함하는 랑쥬뱅 장이론 시뮬레이션(L-FTS) 개발과 응용에 주력한다. 딥러닝 기법을 이용한 연성물질 해석 및 시뮬레이션 가속화 연구를 수행하며, 통계물리학, 딥러닝, AI 등에 관심 있는 학생들의 참여를 환영한다.
