Understanding thermal nature of de Sitter spacetime via inter-detector interaction
Wenting Zhou, Shijing Cheng, Hongwei Yu
The seminar discovery by Gibbons and Hawking that a freely falling detector observes an isotropic background of thermal radiation reveals that de Sitter space is equivalent to a th…
Probing long-range properties of vacuum altered by uniformly accelerating two spatially separated Unruh-DeWitt detectors
Shijing Cheng, Wenting Zhou, Hongwei Yu
In a quantum sense, vacuum is not an empty void but full of virtual particles (fields). It may have long-range properties, be altered, and even undergo phase transitions. It is sug…
Quantum thermal field fluctuation induced corrections to the interaction between two ground-state atoms
Shijing Cheng, Wenting Zhou, Hongwei Yu
We generalize the formalism proposed by Dalibard, Dupont-Roc, and Cohen-Tannoudji [the DDC formalism] in the fourth order for two atoms in interaction with scalar fields in vacuum…
Interatomic interaction of two ground-state atoms in vacuum: contributions of vacuum fluctuations and radiation reaction
Wenting Zhou, Shijing Cheng, Hongwei Yu
We generalize the formalism proposed by Dalibard, Dupont-Roc and Cohen-Tannoudji [the DDC formalism] to the fourth order of the coupling constant, which can be used to study the in…
Spontaneous excitation of an accelerated atom coupled with quantum fluctuations of spacetime
Shijing Cheng, Jiawei Hu, Hongwei Yu
A direct consequence of quantization of gravity would be quantum gravitational vacuum fluctuations which induce quadrupole moments in gravitationally polarizable atoms. In this pap…
Quantum fluctuations of spacetime generate quantum entanglement between gravitationally polarizable subsystems
Shijing Cheng, Hongwei Yu, Jiawei Hu
There should be quantum vacuum fluctuations of spacetime itself, if we accept that the basic quantum principles we are already familiar with apply as well to a quantum theory of gr…
