摘要:

通过改变费米子的时间边界条件,研究了有限温度格点量子色动力学。我们开发的淬火情况下的研究中出现的物理行为,并随后提出了第一个结果的完全动力学计算比较合奏以下和以上的相变。我们表明,低温光谱量的狄拉克运营商是不敏感的边界条件,而在deconfined阶段的非平凡的响应变化的边界条件集。

英文摘要:

Finite temperature lattice QCD is probed by varying the temporal boundary conditions of the fermions. We develop the emerging physical behavior in a study of the quenched case and subsequently present first results for a fully dynamical calculation comparing ensembles below and above the phase transition. We show that for low temperature spectral quantities of the Dirac operator are insensitive to boundary conditions, while in the deconfined phase a non-trivial response to a variation of the boundary conditions sets in.
