Vacuum stress tensor of spinor fields in de Sitter space
Xuan Ye, Yang Zhang
We study the regularized vacuum stress tensor of spinor fields in de Sitter space and its possible contribution to the cosmological constant. Using adiabatic regularization, we sho…

The Conserved Effective Stress Tensor of Gravitational Wave
Yang Zhang, Xuan Ye
We present a detailed study of the effective stress tensor of gravitational wave (GW) as the source for the background Einstein equation and examine three candidates in literature.…
