我们研究了Dyson气体在满足Toda格层次的一组可积统计力学可观测量下的平衡热力学。我们证明了在热力学极限下，这些可积可观测量是满足一组闭式代数状态方程的状态函数，这些方程通过对Toda格层次在连续极限下的直接积分获得。随后，我们通过蒙特卡洛模拟探讨了状态函数的正则性与临界行为同Dyson气体粒子统计之间的联系。我们表明，可积可观测量的性质，如正则性、多值性、尖点奇异性，携带着宏观粒子统计及其定性变化的信息，但存在一些局限性。
英文摘要
We investigate the equilibrium thermodynamics of a Dyson gas in connection with a set of integrable statistical mechanical observables satisfying the Toda Lattice hierarchy. We prove that in the thermodynamic limit, the integrable observables are state functions satisfying a set algebraic equations of state in closed form, obtained from direct integration of the Toda Lattice hierarchy in the continuum limit. We then explore the connection between regularity and critical behaviour of the state functions and the Dyson gas particle statistics via Monte Carlo simulations. We show that the properties of the integrable observables, such as regularity, multivaluedness, cusp singularities, carry information on the macroscopic particle statistics and its qualitative changes but with some limitations.
