Non-minimally Coupled Tachyon and Inflation
Yun-Song Piao, Qing-Guo Huang, Xinmin Zhang +1
In this paper, we consider a model of tachyon with a non-minimal coupling to gravity and study its cosmological effects. Regarding inflation we will show that for a specific coupli…
General Relativistic Effects on Quantum Interference and the Principle of Equivalence
K. K. Nandi, Yuan-Zhong Zhang
Using a novel approach, we work out the general relativistic effects on the quantum interference of de Broglie waves associated with thermal neutrons. The unified general formula i…
Analog of the Fizeau Effect in an Effective Optical Medium
K. K. Nandi, Yuan-Zhong Zhang, P. M. Alsing +2
Using a new approach, we propose an analog of the Fizeau effect for massive and massless particles in an effective optical medium derived from the static, spherically symmetric gra…
Assisted Tachyonic Inflation
Yun-Song Piao, Rong-Gen Cai, Xinmin Zhang +1
The model of inflation with a single tachyon field generates larger anisotropy and has difficulties in describing the formation of the Universe . In this paper we consider a model…
Gravity In A Model Of Multi Branes Alternated Between Minkowski And AdS Spacetime In The Fifth Dimension
Yun-Song Piao, Xinmin Zhang, Yuan-Zhong Zhang
We construct in this paper a multi-brne model with Minkowski and AdS spacetime alternated in the fifth dimension and study the gravity on the brane of our universe. We will show th…
Chern-Simons Term for BF Theory and Gravity as a Generalized Topological Field Theory in Four Dimensions
Han-Ying Guo, Yi Ling, Roh-Suan Tung +1
A direct relation between two types of topological field theories, Chern-Simons theory and BF theory, is presented by using ``Generalized Differential Calculus'', which extends an…
