Asymptotic Symmetries at Spatial Infinity
Sharad Mishra, Kinjal Banerjee, Jishnu Bhattacharyya
We describe asymptotic symmetries at spatial infinity of asymptotically flat spacetimes within the context of a generalization of the Beig-Schmidt-Ashtekar-Romano-framework. We dem…
Constructing Viable Interacting Dark Matter and Dark Energy Models: A Dynamical Systems Approach
Ashmita, Kinjal Banerjee, Prasanta Kumar Das
We study the evolution of FLRW cosmological models for two interacting Dark Matter-Dark Energy Models using dynamical system analysis. Since we are interested in late time e…
de Sitterization via Kerr-Schild
Aditya Sharma, Kinjal Banerjee, Jishnu Bhattacharyya
Spatially homogeneous cosmological spacetimes, evolving in the presence of a positive cosmological constant and matter satisfying some reasonable energy conditions, typically appro…
Connection dynamics of a gauge theory of gravity coupled with matter
Jian Yang, Kinjal Banerjee, Yongge Ma
We study the coupling of the gravitational action, which is a linear combination of the Hilbert-Palatini term and the quadratic torsion term, to the action of Dirac fermions. The s…
Hamiltonian Analysis of Action
Jian Yang, Kinjal Banerjee, Yongge Ma
We study a gravitational action which is a linear combination of the Hilbert-Palatini term and a term quadratic in torsion and possessing local Poincare invariance. Although this a…
Introduction to Loop Quantum Cosmology
Kinjal Banerjee, Gianluca Calcagni, Mercedes Martín-Benito
This is an introduction to loop quantum cosmology (LQC) reviewing mini- and midisuperspace models as well as homogeneous and inhomogeneous effective dynamics.
Some Aspects of Holst and Nieh-Yan Terms in General Relativity with Torsion
Kinjal Banerjee
We explore the relation of the Holst term with the Nieh-Yan term in terms of metric variables. We show that the Holst term indeed affects the classical equations of motion in the p…
Semiclassical environment of collapsing shells
Kinjal Banerjee, Aseem Paranjape
We explore in detail the semiclassical environment of collapsing shells of matter, and determine the semiclassical flux measured by a variety of observers. This study is a prelimin…
Loop Quantization of Polarized Gowdy Model on : Kinematical States and Constraint Operators
Kinjal Banerjee, Ghanashyam Date
In this second paper on loop quantization of Gowdy model, we introduce the kinematical Hilbert space on which appropriate holonomies and fluxes are well represented. The quantizati…
Loop Quantization of Polarized Gowdy Model on : Classical Theory
Kinjal Banerjee, Ghanashyam Date
The vacuum Gowdy models provide much studied, non-trivial midi-superspace examples. Various technical issues within Loop Quantum Gravity can be studied in these models as well as o…
Discreteness Corrections to the Effective Hamiltonian of Isotropic Loop Quantum Cosmology
Kinjal Banerjee, Ghanashyam Date
One of the qualitatively distinct and robust implication of Loop Quantum Gravity (LQG) is the underlying discrete structure. In the cosmological context elucidated by Loop Quantum…
