                     Universality and scaling in physical, biological, and social systems

报告摘要:

The objective of statistical physics is to understand macroscopic behavior of a many-body system from the interactions of the constituents of that system. When many-body systems reach critical states, simple universal and scaling behaviors appear. In this talk, I first introduce the concepts of universality and scaling in critical physical systems [1,2].  I then briefly review some examples of universal and scaling behaviors in physical, biological, and social systems including universal mechanism for critical behavior of lattice systems [3,4], universal finite-size scaling functions of percolation [5] and Ising model [6], universal critical exponents and amplitude ratios [7,8], universal ratio of volume to surface area of proteins [9], universal mechanism for protein aggregation [10], glassy behavior of polymers and proteins [10,11], universal crossover behavior of stock returns [12], etc. Finally, I mention some interesting problems for further studies.
