非紧QED的相(3)

The Phases of Non-Compact QED(3)

Costas Strouthos, John B. Kogut

摘要:

通过计算机模拟研究了非紧三维QED在不同费米子味数N_f下的手征对称性破缺特征。我们考虑费米子场的四分量公式,它是(2+1)维交错费米子结构的连续极限。我们提出的状态方程的理论,在努力了解的性质的手征相变的理论在一个临界数量的费米子口味N_{fc}的初步结果。我们的初步结果表明,N_{fc} ~1.5。

英文摘要:

Non-compact three-dimensional QED is studied by computer simulations to understand its chiral symmetry breaking features for different values of the number of fermion flavors N_f. We consider the four-component formulation for the fermion fields, which arises naturally as the continuum limit of the staggered fermion construction in (2+1) dimensions. We present preliminary results for the equation of state of the theory in an effort to understand the properties of the chiral phase transition of the theory at a critical number of fermion flavors N_{fc}. Our preliminary results indicate that N_{fc}~1.5.
