Energy conditions in new model of loop quantum cosmology
Gaoping Long, Yunlong Liu, Xiangdong Zhang
Recently, a de-Sitter epoch has been found in the new model of loop quantum cosmology which is governed by the scalar constraint with both of Euclidean and Lorentz terms. The singu…
Collision of spinning particles near BTZ black holes
Xulong Yuan, Yunlong Liu, Xiangdong Zhang
We study the collision property of spinning particles near a Bañados-Teitelboim-Zanelli (BTZ) black hole. Our results show that although the center-of-mass energy of two ingoing pa…
Maximal efficiency of the collisional Penrose process with spinning particles in Kerr-Sen black hole
Yunlong Liu, Xiangdong Zhang
We study the collision of two uncharged spinning particles around an extreme Kerr-Sen black hole and calculate the maximal efficiency of the energy extraction from the Kerr-Sen bla…
Kerr-de Sitter and Kerr-anti-de Sitter black holes as accelerators for spinning particles
Songming Zhang, Yunlong Liu, Xiangdong Zhang
It is shown that the Kerr black hole could act as accelerators for spinning particles. In principle, it could obtain arbitrarily high energy for extremal Kerr black hole. In this p…
