具有非静态共形对称性的经典电子模型

Classical electron model with non static conformal symmetry

I. Radinschi, F. Rahaman, M. Kalam, K. Chakraborty

摘要:

洛伦兹提出了一个经典的电子模型,其中电子被假定为只有“电磁质量”。我们将电子模型化为荷电各向异性的理想流体球,承认非静态共形对称性。注意到压力和密度在原点处不是正则的,但有效引力质量处处正则,在极限r->0处为零,即它不必容忍奇异性问题。进一步,我们将内部度规与外部(Reissner-Nordström)度规相匹配,并确定了球对称带电物体(即电子)的质量、电荷和半径的函数中的参数k和r_0的值。

英文摘要:

Lorentz proposed a classical model of electron in which electron was assumed to have only 'electromagnetic mass'. We modeled electron as charged anisotropic perfect fluid sphere admitting non static conformal symmetry. It is noticed that the pressure and density fail to be regular at the origin but effective gravitational mass is regular everywhere and vanishes at the limit r->0 i.e. it does not have to tolerate the problem of singularity. Further, we have matched interior metric with exterior (Reissner-Nordström) metric and determine the values of the parameters k and r_0 (occurring in the solutions) in functions of mass, charge and radius of the spherically symmetric charged objects i.e. electron.
