论文摘要

夸克冷凝物的基本形式是使用限制的场方程得出的外部磁场和温度的任意值。表明,手性冷凝物的结果表达与单点$ q \ bar q $基态波函数($ | ϕ_0(0)|^2 $)成正比。对于没有磁场的光夸克,冷凝物与$σ^{3/2} $成正比($σ$是字符串张力)。数值结果在5个表中显示,并显示与晶格数据非常吻合,既适用于非零磁场$ eb $ and温度$ t $ $ 0 <t <t <t <120 $〜mev,〜$ 0 <eb <4 $ 〜gev $^$^2 $。

The basic form of the quark condensate for arbitrary values of external magnetic field and temperature, is derived using the field equations with account of confinement. The resulting expression of the chiral condensate is shown to be proportional to square of the singlet $q\bar q$ ground state wave function at origin, $|ϕ_0(0)|^2$. For light quarks without magnetic field the condensates are proportional to $σ^{3/2}$ ($σ$ is the string tension). Numerical results are presented in 5 Tables and shown to be in good agreement with the lattice data, both for nonzero magnetic field $eB$ and temperature $T$ in the range $0 <T < 120$~MeV,~ $0 <eB <4$~GeV$^2$.
