Abstract:
Classical dynamical systems consisting more than three objects are often chaotic. However, there are some many body systems, such as spin chains, having enough many conserved quantities, making it integrable. Unfortunately there are no general rule to determine whether a dynamical many body systems is integrable. In this talk, I will introduce a class of integrable systems that are represented by chessboard-like graphs, whose conserving Hamiltonians are represented by geometric paths on the graph, and how to quantize these system.
