題目:Living on the edge:Black Holes as Quantum Gravity Lampposts (懸于一線:黑洞作為量子引力探索的燈塔)
時間:2024.6.25 15:00-17:00
地點:4號科研樓C區(qū)(物理樓)567會議室
內(nèi)容介紹:“We live in an era marked by the LIGO Laboratory discovery of gravitational waves, emitted when two black holes coalesce, and the Event Horizon Telescope imaging of black holes. While these amazing discoveries crystallise Einstein’s theory of general relativity they also beg for a fresh look at the problem of unifying gravity and quantum field theory. These two theories constitute our current understanding of Nature but are notoriously at odds with each other. I will first review basic facts about black holes and then argue in favour of a recent approach that aims at shortcutting the problem of the absence of a theory of quantum gravity. This will be achieved by introducing a quantum gravity model independent approach focussed on effective metric descriptions of quantum black holes. We believe that our findings will herald novel ways to explore quantum corrections to black hole dynamics with impact for our understanding of the fabric of space-time.”

桑尼諾教授因開創(chuàng)性地進行了規(guī)范理論共形結構的分析和數(shù)值研究而廣受認可,這些理論是基本相互作用的理論。他還構建了標準模型的最小復合擴展,并最近發(fā)現(xiàn)了四維漸近安全理論。近期,他還應用并發(fā)展了源于理論物理學的數(shù)學工具,以描述人類和病毒層面上傳染病的演變。他的工作跨越了粒子物理學和宇宙學的多個領域,從標準模型的明亮和黑暗擴展,到膨脹宇宙學,再到基本相互作用理論的數(shù)學基礎。
