The Casimir force on a piston in the spacetime with extra compactified dimensions
Hongbo Cheng
A one-dimensional Casimir piston for massless scalar fields obeying Dirichlet boundary conditions in high-dimensional spacetimes within the frame of Kaluza-Klein theory is analyzed…
The circular loop equation of a cosmic string with time-varying tension
Hongbo Cheng, Yunqi Liu
The equation of circular loops of cosmic string with time-dependent tension is studied in the Minkowski spacetime and Robertson-Walker universe. We find that, in the case where the…
The circular loop equation of a cosmic string with time-varying tension in de Sitter spacetimes
Yunqi Liu, Hongbo Cheng
In this work the equation of circular loops of cosmic string possessing time-dependent tension is studied in the de Sitter spacetime. We find that the cosmic string loops with init…
The asymptotic behavior of Casimir force in the presence of compactified universal extra dimensions
Hongbo Cheng
The Casimir effect for parallel plates in the presence of compactified universal extra dimensions within the frame of Kaluza-Klein theory is analyzed. Having regularized and discus…
On the Casimir effect for parallel plates in the spacetime with one extra compactified dimension
Hongbo Cheng
In this paper, the Casimir effect for parallel plates in the presence of one compactified universal extra dimension is reexamined in detail. Having regularized the expressions of C…
The evolution of cosmic string loops in Kerr-de Sitter spacetimes
Zhengyan Gu, Hongbo Cheng
The equation of cosmic string loops in Kerr-de Sitter spacetimes is derived. Having solved the equation numerically, we find that the loops can expand and exist except for too smal…
