Optimal estimation of parameters for scalar fields in expanding universe exhibiting Lorentz invariance violation
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We address the optimal estimation of quantum parameters, in the framework of local quantum estimation theory, for a massive scalar quantum field in the expanding Robertson-Walker u…

Radiative process of two entanglement atoms in de Sitter spacetime
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We investigate the radiative processes of a quantum system composed by two identical two-level atoms in the de Sitter spacetime, interacting with a conformally coupled massless sca…
