Maxwell field with gauge fixing term in de Sitter space: exact solution and stress tensor
Yang Zhang, Xuan Ye
The Maxwell field with a general gauge fixing (GF) term is nontrivial, not only the longitudinal and temporal modes are mixed up in the field equations, but also unwanted consequen…

A massless scalar field in Robertson-Walker spacetimes: Adiabatic regularization and Green's function
Yang Zhang, Bo Wang, Xuan Ye
We study adiabatic regularization of a coupling massless scalar field in general spatially flat Robertson-Walker (RW) spacetimes. For the conformally-coupling, the 0th-order regula…

Adiabatic regularization and Green's function of a scalar field in de Sitter space: Positive energy spectrum and no trace anomaly
Yang Zhang, Xuan Ye, Bo Wang
In the conventional adiabatic regularization the vacuum ultraviolet divergences of a quantum field in curved spacetime are removed by subtracting the -mode of the stress tensor…
