摘要
研究狭义相对论中的变形色散关系,得到Lorentz破缺和光速变化的关系,分析量子引力放大效应作用下光速的变化.另外,根据修正色散关系计算白矮星的半径-质量关系式.文献(Amelino-Camelia G.Living Rev Relati,2013,16(2):7-105.)指出白矮星半径的变化可能存在一些观测效应,但他们并没有讨论这些效应的物理根源,研究结果表明:在放大效应或极高密度情况时,白矮星半径的改变才比较明显.
The deformed dispersion relation in special theory of relativity is studied in this paper,the relation of Lorentz breaking and change of the light speed is obtained,we analyze that change of light speed under the action of quantum gravity magnified effect.In addition,the relation of radius-mass is calculated according to the modified dispersion relation. Literature（ Amelino-Camelia G. Living Rev Relati,2013,16（2） ：7-105.） pointed out that it is possible to exist some observation effects for changing of white dwarf radius,but they did not discuss the physical origin of these effects. The results of this paper show that in the case of amplification effect or extremely high density,the change of white dwarf radius is more obvious.
