Temperature effect on the power spectrum in inflation
Shaoyu Yin, Bin Wang, Ru-Keng Su
We examine the effect of the thermal vacuum on the power spectrum of inflation by using the thermal field dynamics. We find that the thermal effect influences the CMB anisotropy at…
Hawking radiation in a -dimensional static spherically-symmetric black Hole surrounded by quintessence
Songbai Chen, Bin Wang, Rukeng Su
We present a solution of Einstein equations with quintessential matter surrounding a -dimensional black hole, whose asymptotic structures are determined by the state of the quin…
Influence of Lorentz violation on Dirac quasinormal modes in the Schwarzschild black hole spacetime
Songbai Chen, Bin Wang, Rukeng Su
Using the third-order WKB approximation and monodromy methods, we investigate the influence of Lorentz violating coefficient (associated with a special axial-vector field…
Thermodynamic Geometry and Critical Behavior of Black Holes
Jianyong Shen, Rong-Gen Cai, Bin Wang +1
Based on the observations that there exists an analogy between the Reissner-Nordström-anti-de Sitter (RN-AdS) black holes and the van der Waals-Maxwell liquid-gas system, in which…
An alternative explanation of the conflict between 1/R gravity and solar system tests
Cheng-Gang Shao, Rong-Gen Cai, Bin Wang +1
Recently the 1/R gravity has been proposed in order to explain the accelerated expansion of the universe. However, it was argued that the 1/R gravity conflicts with solar system te…
Dirac Cosmology and the Acceleration of the Contemporary Universe
Cheng-Gang Shao, Jianyong Shen, Bin Wang +1
A model is suggested to unify the Einstein GR and Dirac Cosmology. There is one adjusted parameter in our model. After adjusting the parameter in the model by using the…
Slowly rotating proto strange stars in Quark mass density- and temperature- dependent model
Jianyong Shen, Yun Zhang, Bin Wang +1
Employing the Quark Mass Denisity- and temperature- dependent model and the Hartle's method, We have studied the slowly rotating strange star with uniform angular velocity. The mas…
Quasinormal modes in time-dependent black hole background
Cheng-Gang Shao, Bin Wang, Elcio Abdalla +1
We have studied the evolution of the massless scalar field propagating in time-dependent charged Vaidya black hole background. A generalized tortoise coordinate transformation were…
Numerical simulation of Quasi-Normal Modes in time-dependent background
Li-Hui Xue, Zai-Xiong Shen, Bin Wang +1
We study the massless scalar wave propagation in the time-dependent Schwarzschild black hole background. We find that the Kruskal coordinate is an appropriate framework to investig…
Geometry and topology of two kinds of extreme Reissner-Nordstrm-anti-de Sitter black holes
Bin Wang, Elcio Abdalla, Ru-Keng Su
Different geometrical and topological properties have been shown for two kinds of extreme Reissner-Nordstrm-anti-de Sitter black holes. The relationship between the geome…
Entropy, topology of two-dimensional extreme black holes
Bin Wang, Ru-Keng Su
Through direct thermodynamic calculations we have shown that different classical entropies of two-dimensional extreme black holes appear due to two different treatments, namely Haw…
Quantum entropy of two-dimensional extreme charged dilaton black hole
Bin Wang, Ru-Keng Su, P. K. N. Yu
By using Hawking's treatment as well as Zaslavskii's treatment respectively and the brick wall model, two different values of classical entropy and quantum entropy of scalar fields…
Two kinds of extreme black holes and their classification
Bin Wang, Ru-Keng Su
According to different topological configurations, we suggest that there are two kinds of extreme black holes in the nature. We find that the Euler characteristic plays an essentia…
Can nonextremal Reissner-Nordstrom black hole become extremal by assimilating infalling charged particle and shell?
Bin Wang, Ru-Keng Su, P. K. N. Yu +1
By using the gedanken experiments suggested by Bekenstein and Rosenzweig, we have shown that nonextremal Reissner-Nordstrom black hole cannot turn into extremal one by assimilating…
Geometry of the extreme Kerr black holes
Bin Wang, Ru-Keng Su, P. K. N. Yu
Geometrical properties of the extreme Kerr black holes in the topological sectors of nonextreme and extreme configurations are studied. We find that the Euler characteristic plays…
A possible explanation of the clash for black hole entropy in the extremal limit
Ru-Keng Su, Bin Wang, P. K. N. Yu +1
It is shown that the classical entropy of the extremal black hole depends on two different limits procedures. If we first take the extremal limit and then the boundary limit, the e…
