Vacuum fluctuation force on a rigid Casimir cavity in de Sitter and Schwarzschild-de Sitter spacetime
Xiang Chen
We investigate the net force on a rigid Casimir cavity generated by vacuum fluctuations of electromagnetic field in three cases, de Sitter spacetime, de Sitter spacetime with weak…
Charged black holes in nonlinear massive gravity
Yi-Fu Cai, Damien A. Easson, Caixia Gao +1
We find static charged black hole solutions in nonlinear massive gravity. In the parameter space of two gravitational potential parameters we show that below the Compton w…
Qubits and oriented matroids in four time and four space dimensions
J. A. Nieto
We establish a connection between 4-rebits (real qubits) and the Nambu-Goto action with target `spacetime' of four time and four space dimensions ((4+4)-dimensions)). We motivate t…
Emergent Universe Scenario via Quintom Matter
Yi-Fu Cai, Mingzhe Li, Xinmin Zhang
The emergent universe scenario provides a possible alternative to bouncing cosmology to avoid the Big Bang singularity problem. In this paper we study the realization of the emerge…
IR Divergence in Inflationary Tensor Perturbations from Fermion Loops
Kaixi Feng, Yi-Fu Cai, Yun-Song Piao
We estimate fermion loop corrections to the two-point correlation function of primordial tensor perturbations in a slow-roll inflationary background. We particularly compute an exp…
Towards a Nonsingular Bouncing Cosmology
Yi-Fu Cai, Damien A. Easson, Robert Brandenberger
We present a nonsingular bouncing cosmology using single scalar field matter with non-trivial potential and non-standard kinetic term. The potential sources a dynamical attractor s…
