外磁场中N $_f$ = 1 QCD:交错费米子

N$_f$ = 1 QCD in External Magnetic Fields: Staggered Fermions

Paolo Cea, Leonardo Cosmai

摘要:

本文研究了格点上外加磁场的N $_f$ = 1量子色动力学。背景场是通过所谓的薛定谔泛函引入的。我们采用标准交错费米子与恒定裸质量$am = 0.025$和磁场恒定磁通量高达$a^2 e H \simeq 2.3562$。我们发现解禁闭温度和手征对称性恢复温度与外加磁场的强度无关。我们的方法使我们能够容易地研究外部磁场对QCD热力学的影响。我们确定了外加磁场对强相互作用物质的自由能、压强和状态方程的影响。

英文摘要:

We investigate N$_f$ = 1 QCD in external magnetic fields on the lattice. The background field is introduced by means of the so-called Schrodinger functional. We adopt standard staggered fermions with constant bare mass $am = 0.025$ and magnetic fields with constant magnetic flux up to $a^2 e H \simeq 2.3562$. We find that the the deconfinement and chiral symmetry restoration temperatures do not depend on the strength of the applied magnetic field. Our method allow us to easily study the effects of the external magnetic fields on the QCD thermodynamics. We determine the influences of applied magnetic fields to the free energy, pressure, and equation of state of strongly interacting matter.
