各向异性格点上强耦合格点量子色动力学的规范修正

Gauge Corrections to Strong Coupling Lattice QCD on Anisotropic Lattices

Jangho Kim, Marc Klegrewe, Wolfgang Unger

摘要:

具有交错费米子的格点量子色动力学可以用对偶变量形式来描述有限重子密度符号问题。在过去,我们已经进行了模拟强耦合制度,包括领先的秩序规范修正。为了改变固定$β$的温度,必须引入裸各向异性。在这次演讲中,我们将扩展我们的工作,包括从物理各向异性$a_σ$ / $a_τ= ξ(γ, β)$,这是必要的明确定位的临界端点和一阶线的手征过渡的非微扰测定的结果。

英文摘要:

Lattice QCD with staggered fermions can be formulated in dual variables to address the finite baryon density sign problem. In the past we have performed simulations in the strong coupling regime, including leading order gauge corrections. In order to vary the temperature for fixed $β$ it was necessary to introduce a bare anisotropy. In this talk we will extend our work to include results from a non-perturbative determination of the physical anisotropy $a_σ$/$a_τ= ξ(γ, β)$, which is necessary to unambiguously locate the critical end point and the first order line of the chiral transition.
