存在相互作用场时(1 + 1)de Sitter空间的不稳定性

Instability of (1+1) de sitter space in the presence of interacting fields

Myron Bander

摘要:

研究了由相互作用场引起的二维(1 + 1)de Sitter空间的不稳定性.对于平坦闵可夫斯基空间,几种相互作用费米子模型可以转化为自由玻色子模型,反之亦然。结果表明,相互作用费米子理论不会导致任何不稳定性,而相互作用玻色子sine-Gordon模型会导致de Sitter对称性的破坏和S矩阵真空期望值的消失.

英文摘要:

Instabilities of two dimensional (1+1) de Sitter space induced by interacting fields are studied. As for the case of flat Minkowski space, several interacting fermion models can be translated into free boson ones and vice versa. It is found that interacting fermion theories do not lead to any instabilities, while the interacting bosonic sine-Gordon model does lead to a breakdown of de Sitter symmetry and to the vanishing of the vacuum expectation value of the S matrix.
