【摘要】：本文研究了狭义相对论中的变形色散关系,得到了Lorentz破缺和光速变化的关系,分析了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了白矮星的半径-质量关系式。Camelia等人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,本文中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。暗物质是天体物理与粒子物理中的重要研究课题,本文对一类新的暗物质—Q泡暗物质进行研究。通过能量和动量的修正色散关系计算了Q泡在稳定状态下的能量和半径,讨论了量子时空效应下Q泡能级的跃迁。另外,还分析和比较了扰动情况下Q泡的能级分布和粒子释放。在广义相对论和弦引力模型框架中,研究了不同类型的Kerr中子星的表面温度的分布,即Kerr-Newman-Kasuya,Kerr-Newman-VGM以及Kerr-Sen中子星的极/赤温度比。本文分别计算了转动较慢和较快中子星的表面温差,并分析和比较了温度分布的物理规律。结果发现这些Kerr型中子星的表面温度分布有一定差别,本文的研究为进一步的天文观测提供了一种新的思路和方法。本论文中具有创新性工作如下:1、根据修正的相对论色散关系计算了白矮星半径的量子引力修正,分析了不同质量和放大指数白矮星半径的变化。2、研究了量子时空背景下Q泡暗物质的能量分布,计算了能量修正和动量修正下Q泡的能级分布,还分析了扰动情况下的Q泡能级和粒子释放。3、研究了Kerr-型中子星的表面温度分布,计算了K-N-K中子星、K-N-VGM中子星以及K-Sen中子星赤/极的温差,分析和比较了不同中子星的温度分布规律。
[Abstract]:In this paper, we study the relation of deformed dispersion in special relativity, obtain the relationship between the Lorentz breaking and the variation of the speed of light, and analyze the variation of the speed of light under the effect of quantum gravitational amplification. In addition, according to the modified dispersion relation, the radius-mass relation of white dwarf is calculated. Camelia et al point out that there may be some observational effects in the variation of white dwarf radius, but they do not discuss the physical origin of these effects. The results show that the change of the radius of white dwarf is more obvious in the case of amplification effect or extremely high density. Dark matter is an important research topic in astrophysics and particle physics. The energy and radius of Q bubble in stable state are calculated by the modified dispersion relation of energy and momentum, and the transition of Q bubble energy level under quantum space-time effect is discussed. In addition, the energy level distribution and particle release of Q bubble under disturbance are analyzed and compared. In the framework of the general relativistic and chord gravity model, the surface temperature distributions of different types of Kerr neutron stars, namely, Kerr-Newman-Kasuya,Kerr-Newman-VGM and Kerr-Sen neutron stars, are studied. In this paper, the surface temperature difference of slow rotating neutron stars and fast neutron stars are calculated, and the physical laws of temperature distribution are analyzed and compared. The results show that there are some differences in surface temperature distribution of these Kerr neutron stars. The present study provides a new way of thinking and method for further astronomical observation. The innovative work in this thesis is as follows: 1. Based on the modified relativistic dispersion relation, the quantum gravitational correction of the radius of white dwarf star is calculated. The variation of radius of white dwarf star with different mass and amplification index is analyzed. The energy distribution of Q bubble dark matter under the background of quantum space-time is studied. The energy level distribution of Q bubble is calculated under energy correction and momentum correction. The Q bubble energy level and particle release. 3 are analyzed. The surface temperature distribution of Kerr- neutron star is studied. The temperature difference of K-N-K neutron star K-N-VGM neutron star and K-Sen neutron star is calculated. The temperature distribution of different neutron stars is analyzed and compared.
