标题： Lyapunov exponents in Minkowskian U(1) gauge theory

摘要： U(1)规范场在从禁闭相到库仑相的相变过程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，单极子场具有与原始U(1)场相同的李雅普诺夫指数。 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 that the monopole field carries the same Lyapunov exponent as the original U(1) field. Evidence is found that monopole fields stay chaotic in the continuum whereas the photon fields are regular.
