Quintessence model in the late Universe
L. K. Duchaniya, Jackson Levi Said, B. Mishra +1
Scalar fields have shown great potential in inducing tailored modifications compared to cosmic evolution in the CDM model. We investigate a quintessence model with five physical…
Accelerating Unruh-DeWitt detectors coupled with a spinor field
Dawei Wu, Shan-Chang Tang, Yu Shi
The behavior of accelerating Unruh-DeWitt detectors coupled with a spinor field in (3+1)-dimensional spacetime is investigated. For a single point-like detector with Gaussian switc…
Exact conditions for antiUnruh effect in (1+1)-dimensional spacetime
Dawei Wu, Ji-chong Yang, Yu Shi
Exact conditions for antiUnruh effect in (1+1)-dimensional spacetime are obtained. For detectors with Gaussian switching functions, the analytic results are similar to previous one…
Birth and death of entanglement between two accelerating Unruh-DeWitt detectors coupled with a scalar field
Dawei Wu, Shan-Chang Tang, Yu Shi
We consider two accelerating Unruh-DeWitt detectors coupled linearly or quadratically with a scalar field. We show that entanglement can be created by acceleration, and is divergen…
Kinetic Spin Decoherence in a Gravitational Field
Yue Dai, Yu Shi
We consider a wave packet of a spin-1/2 particle in a gravitational field, the effect of which can be described in terms of a succession of local inertial frames. It is shown that…
