Thermal nature of de Sitter spacetime and spontaneous excitation of atoms
Zhiying Zhu, Hongwei Yu
We consider, in de Sitter spacetime, both freely falling and static two-level atoms in interaction with a conformally coupled massless scalar field in the de Sitter-invariant vacuu…

Fulling-Davies-Unruh effect and spontaneous excitation of an accelerated atom interacting with a quantum scalar field
Zhiying Zhu, Hongwei Yu
We investigate, from the point of view of a coaccelerated frame, the spontaneous excitation of a uniformly accelerated two-level atom interacting with a scalar field in a thermal s…
