标题： Compact QED under scrutiny: it's first order

摘要： 我们报告了关于具有威尔逊作用量的4维紧致纯U(1)规范理论有限尺寸标度分析的新结果。 在Borgs-Kotecky有限尺寸标度方案中研究了环路能量的几个累积量，我们发现了强烈的一阶相变证据，并给出了热力学极限下临界耦合的高精度值。 显示英文摘要

摘要： We report new results from our finite size scaling analysis of 4d compact pure U(1) gauge theory with Wilson action. Investigating several cumulants of the plaquette energy within the Borgs-Kotecky finite size scaling scheme we find strong evidence for a first-order phase transition and present a high precision value for the critical coupling in the thermodynamic limit.
