摘要:

平面 Thirring 模型被认为在单味费米子情形下具有一个强耦合临界点。我们考察该临界区域内双线性凝聚的计算,以及通过状态方程对其进行表征。由于该计算在数值上具有挑战性,我们研究了改进的 Dirac 算符。我们给出了采用有理混合 Monte Carlo 方案的不同计算方法的结果,以及双线性凝聚、状态方程和相关临界指数的计算。文中考虑了 Overlap 和 domain wall Dirac 算符及其变体。

英文摘要:

The planar Thirring model is thought to have a strongly coupled critical point for a single flavour of fermion. We look at the calculation of the bilinear condensate in this critical region, and its characterisation via an equation of state. Since the computation is numerically challenging we investigate improved Dirac operators. We present findings on different methods of calculation using a rational hybrid Monte Carlo scheme, and calculations of the bilinear condensate, an equation of state, and the associated critical exponents. Overlap and domain wall Dirac operators, and variants therein are considered.
