Based on Dyson- Schwinger Equations of quark propagator, we calculate quark-gluon mixed vacuum condensates 〈0|∶g_sσ_ μν G_ μν q∶|0〉 and quark vacuum condensates 〈0|∶q∶|0〉 which are not only related to virtuality of quark in vacuum state but also characterize the space width of quark distribution in the vacuum.
基于夸克传播子的DysonSchwinger方程,计算了夸克胶子混合真空凝聚和夸克真空凝聚。

It is shown that the vacuum condensates of d=6 operators still have notable effects.
在势模型的框架下,通过粲夸克偶素及底夸克偶素能谱的计算,研究了由高维夸克胶子凝聚描述的非微扰QCD效应结果表明:六维算符真空凝聚仍有明显的贡献;单圈微扰修正在散射和湮灭过程中的贡献几乎相同,但与同一级的非微扰QCD的贡献符号相反

By solving the Gap equation, we found that the contribution of the modification to quark-antiquqrk condensation is obvious, though the main results of vacuum condensation remain.
通过计算 ,发现这种对大r行为的修改虽然能够使真空凝聚保持在r2 关联核下的主要性质 ,但它的影响仍然是显著的 。

The Wilson fermion condensates in the lattice Schwinger model is calculated by using improved Hamiltonian and variational method.
用改进的哈密顿量和变分法计算格点(1+1)维QED(Schwinger模型)中Wilson费米子真空凝聚<>,结果(同使用未改进的哈密顿量的计算结果相比较)与Wilson参数r的依赖关系明显地减小了。

补充资料:BCS凝聚能(BCScondensationenergy)
BCS凝聚能(BCScondensationenergy)
一般将T=0K时的超导基态能量Es(0)与正常态费米球分布能量En(0)之差称BCS凝聚能。由BCS理论给出:
Es(0)-En(0)=-N(0)Δ2(0)/2
由此可知,Es(0)<En(0),能隙2Δ(0)的出现,系统将从正常态转入超导态而发生超导相变。
