【摘要】：本文研究了狹義相對論中的變形色散關系,得到了Lorentz破缺和光速變化的關系,分析了量子引力放大效應作用下光速的變化。另外,根據(jù)修正色散關系計算了白矮星的半徑-質量關系式。Camelia等人指出白矮星半徑的變化可能存在一些觀測效應,但他們并沒有討論這些效應的物理根源,本文中結果表明在放大效應或極高密度情況時,白矮星半徑的改變才比較明顯。暗物質是天體物理與粒子物理中的重要研究課題,本文對一類新的暗物質—Q泡暗物質進行研究。通過能量和動量的修正色散關系計算了Q泡在穩(wěn)定狀態(tài)下的能量和半徑,討論了量子時空效應下Q泡能級的躍遷。另外,還分析和比較了擾動情況下Q泡的能級分布和粒子釋放。在廣義相對論和弦引力模型框架中,研究了不同類型的Kerr中子星的表面溫度的分布,即Kerr-Newman-Kasuya,Kerr-Newman-VGM以及Kerr-Sen中子星的極/赤溫度比。本文分別計算了轉動較慢和較快中子星的表面溫差,并分析和比較了溫度分布的物理規(guī)律。結果發(fā)現(xiàn)這些Kerr型中子星的表面溫度分布有一定差別,本文的研究為進一步的天文觀測提供了一種新的思路和方法。本論文中具有創(chuàng)新性工作如下:1、根據(jù)修正的相對論色散關系計算了白矮星半徑的量子引力修正,分析了不同質量和放大指數(shù)白矮星半徑的變化。2、研究了量子時空背景下Q泡暗物質的能量分布,計算了能量修正和動量修正下Q泡的能級分布,還分析了擾動情況下的Q泡能級和粒子釋放。3、研究了Kerr-型中子星的表面溫度分布,計算了K-N-K中子星、K-N-VGM中子星以及K-Sen中子星赤/極的溫差,分析和比較了不同中子星的溫度分布規(guī)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.
