A study on the dependence of the dimensionless Brans-Dicke parameter on the scalar field and their time dependence
Sudipto Roy, Surajit Chattopadhyay, Antonio Pasqua
The present paper reports a study on the dimensionless parameter in Brans-Dicke theory. Based on a particular choice of scale factor , we have investigated the signature fli…
A Study on Ricci Dark Energy in Bulk-Brane Interaction
Surajit Chattopadhyay
In this work we have investigated the effects of the interaction between a brane universe and the bulk in which it is embedded. Considering the effects of the interaction between a…
A dark energy with higher order derivatives of in the modified gravity
Antonio Pasqua, Surajit Chattopadhyay, Ratbay Myrzakulov
In this paper, we consider a recently proposed model of Dark Energy (DE) which contains three terms (one proportional to the squared Hubble parameter, one to the first derivative w…
Extended holographic Ricci dark energy in chameleon Brans-Dicke cosmology
Surajit Chattopadhyay
In the present work we have studied some features of the generalized Brans-Dicke (BD) model in which the scalar field is allowed to couple non-minimally with matter sector. Extende…
A reconstruction of modified holographic Ricci dark energy in gravity
Antonio Pasqua, Surajit Chattopadhyay, Iuliia Khomenko
In this paper, we consider a recently proposed model of Dark Energy (DE) know as Modified Holographic Ricci DE (MHRDE) (which is function of the Hubble parameter and its first deri…
