标题： Monopoles and Lyapunov Exponents in U(1) Lattice Gauge Theory

摘要： U(1)规范场在从约束相到库仑相的相变中被分解为单极子部分和光子部分。 我们分析了由量子蒙特卡洛模拟初始化的此类规范场构型的领先李雅普诺夫指数。 我们观察到单极子密度的大小与李雅普诺夫指数之间存在强烈关系。 有证据表明，单极子场在连续极限下仍保持混沌，而光子场则是规则的。 显示英文摘要

摘要： U(1) gauge fields are decomposed into a monopole and photon part across the phase transition from the confinement to the Coulomb phase. We analyze the leading Lyapunov exponents of such gauge field configurations on the lattice which are initialized by quantum Monte Carlo simulations. We observe a strong relation between the sizes of the monopole density and the Lyapunov exponent. Evidence is found that monopole fields stay chaotic in the continuum whereas the photon fields are regular.
