相互作用磁场和扭转场的约束势

Confining potential from interacting magnetic and torsion fields

Patricio Gaete, José A. Helaÿel-Neto

摘要:

采用规范不变但依赖于路径的变量形式,研究了有背景电磁场存在时扭转场与光子的耦合。我们明确地表明,在恒定的电场强度的期望值的情况下,静态电位仍然库仑,而在恒定的磁场强度的期望值的情况下,得到一个限制电位。这一结果与存在外部磁场的情况下轴状粒子与光子的通常耦合有显着的定性偏离。

英文摘要:

Adopting the gauge-invariant but path-dependent variables formalism, we study the coupling of torsion fields with photons in the presence of an external background electromagnetic. We explicitly show that, in the case of a constant electric field strength expectation value, the static potential remains Coulombic, while in the case of a constant magnetic field strength expectation value a confining potential is obtained. This result displays a marked qualitative departure from the usual coupling of axionlike particles with photons in the presence of an external magnetic field.
