帶電dilaton黑洞時(shí)空下的動(dòng)態(tài)疇壁
發(fā)布時(shí)間:2022-01-20 03:35
當(dāng)n維帶電黑洞全空間具有非漸近平坦和非漸近(A)dS的特性,我們研究了這種背景時(shí)空下n-1維疇壁世界的動(dòng)力學(xué)。研究發(fā)現(xiàn)運(yùn)動(dòng)的疇壁世界總是可以穿過黑洞視界。對(duì)于疇壁的運(yùn)動(dòng),dilaton耦合常數(shù)a和壓強(qiáng)密度比w是主要控制參數(shù)。疇壁世界在視界外的運(yùn)動(dòng)類型一般分為五種:一直加速膨脹,減速達(dá)到勻速膨脹,減速膨脹到極大值后塌縮進(jìn)入視界,一次反彈,加速塌縮進(jìn)入視界。但是存在一種多個(gè)參數(shù)調(diào)節(jié)的情況,疇壁世界先減速膨脹到速度極小值后加速膨脹。通過分析運(yùn)動(dòng)疇壁的演化方程和速度圖像,揭示了反彈可以發(fā)生且在本論文的模型中不會(huì)出現(xiàn)疇壁世界的周期性反彈。更進(jìn)一步針對(duì)dilaton場(chǎng)對(duì)于疇壁世界的影響,我們引入了帶電拓?fù)浜诙茨P头治隽诉@種背景時(shí)空下的疇壁世界加速膨脹情形。通過對(duì)比所有時(shí)空背景下的動(dòng)力學(xué)方程,發(fā)現(xiàn)對(duì)于疇壁世界的膨脹,在dilaton場(chǎng)和麥克斯韋場(chǎng)之間的耦合效果或者是抑制或者是促進(jìn)。這種抑制或促進(jìn)膨脹的的選擇依賴于不同的黑洞模型。當(dāng)我們選擇加速膨脹疇壁的狀態(tài)為輻射時(shí)期w=1/3或物質(zhì)時(shí)期w=0,得到了各個(gè)背景時(shí)空下dilaton場(chǎng)和麥克斯韋場(chǎng)的耦合常數(shù)a的范圍。因此,發(fā)現(xiàn)耦合的的強(qiáng)弱依賴于黑洞模型。同...
