Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Kerr-Newman型时空中Majorana费米子的存在性问题
Kerr-Newman型时空 Majorana费米子 存在性
2023/11/29
Dirac方程最初是Dirac为解决Minkowski时空中Klein—Gordon方程的粒子的负几率与负能问题建立的。1980年，Weinberg和Witten证明了引力无法量子化，所以为了将引力引入量子场论中，数学和物理学家将平直时空的Dirac方程推广到弯曲时空的Dirac方程，弯曲时空Dirac方程表示了任一自由费米子物质场在时空背景所应满足的场方程，是宇宙学研究的核心问题。2000年Fi...
