Thick accretion disk configurations around a compact object in the brane-world scenario
《Communications in Theoretical Physics》2023年第11期76-83,共8页Yunzhu Wei Songbai Chen Jiliang Jing 
supported by the National Natural Science Foundation of China under Grant Nos.12275078,11875026,12035005 and 2020YFC2201400.
We have studied the equipotential surfaces of a thick accretion disk around a Casadio-Fabbri-Mazzacurati compact object in the brane-world scenario,which possesses a mass parameter together with a parameterized post-N...

Bouncing scenario of general relativistic hydrodynamics in extended gravity
《Communications in Theoretical Physics》2021年第2期96-101,共6页A Y Shaikh B Mishra 
In this paper,we have framed bouncing cosmological model of the Universe in the presence of general relativistic hydrodynamics in an extended theory of gravity.The metric assumed here is the flat Friedmann–Robertson...

A view of compact configurations from the R+γe^xT scenario
《Communications in Theoretical Physics》2020年第3期38-45,共8页Aisha Siddiqa 
This paper presents a picture of compact structures for the f(R,T)model of the form R+γe^χT,withγandχbeing parameters.The poly tropic equation of state and the MIT bag model reflect the pressure density relation f...

Anisotropic Inflationary Scenario Via Generalized Chaplygin Gas Model
《Communications in Theoretical Physics》2016年第5期653-658,共6页Abdul Jawad Shamaila Rani 
We investigate generalized chaplygin gas for warm inflationary scenario in the context of locally rotationally symmetric Bianchi type I universe model.We assume two different cases of dissipative coefficient,i.e.,cons...

Phantom-Like Effects on Warped DGP Brane
《Communications in Theoretical Physics》2010年第10期773-780,共8页Kourosh Nozari Tahereh Azizi 
We study phantom-like effect on the DGP brane embedded in a five-dimensional AdS bulk. We show that this effect can be realized without phantom matter on this warped DGP brahe. We investigate the role played by the bu...

An Interacting Two-Fluid Scenario for Quintom Dark Energy被引量：2
《Communications in Theoretical Physics》2005年第4X期762-768,共7页ZHANG Xin 
国家自然科学基金
The Quintom dark energy is a proposal that explains the recent observations that mildly favor the equation of state of dark energy ω crossing -1 near the past. The Quintom model is often constructed by two scalar fie...

Statefinder Parameters for Coupled Quintessence Scenario in a Power Law Case
《Communications in Theoretical Physics》2005年第3X期573-576,共4页ZHANG Xin 
国家自然科学基金
We investigate a coupled quintessence scenario, which can provide a natural solution to the cosmic coincidence problem. We assume that the mass of dark matter particles depends on a power law function of the scalar fi...

Exact Solution in the New Inflation Scenario with Induced Gravity被引量：1
《Communications in Theoretical Physics》2001年第10期509-512,共4页WANG Wen-Fu 
Taking the Hubble parameter directly as a function of the scalar field instead of as a function of time,H = H( ), we present a new exact solution in the new inflation model with induced gravity. This includes solution...
