Dynamics of interacting phantom scalar field dark energy in Loop Quantum Cosmology
Xiangyun Fu, Hongwei Yu, Puxun Wu
We study the dynamics of a phantom scalar field dark energy interacting with dark matter in loop quantum cosmology (LQC). Two kinds of coupling of the form (case I)…

Brownian motion of a charged test particle driven by vacuum fluctuations near a dielectric half-space
Hongwei Yu, Xiangyun Fu, Puxun Wu
We study the Brownian motion of a charged test particle driven by quantum electromagnetic fluctuations in the vacuum region near a non-dispersive and non-absorbing dielectric half-…

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…
