Geodesic Congruences in the Palatini f(R) Theory
Fatimah Shojai, Ali Shojai
We shall investigate the properties of a congruence of geodesics in the framework of Palatini f(R) theories. We shall evaluate the modified geodesic deviation equation and the Rayc…
f(R) Quantum Cosmology
Ali Shojai, Fatimah Shojai
We have quantized a flat cosmological model in the context of the metric f(R) models, using the causal Bohmian quantum theory. The equations are solved and then we have obtained ho…
Causal loop quantum cosmology in momentum space
Ali Shojai, Fatimah Shojai
We shall show that it is possible to make a causal interpretation of loop quantum cosmology using the momentum as the dynamical variable. We shall show that one can derive Bohmian…
On the Green's function and iterative solutions of Loop Quantum Cosmology
Fatimah Shojai, Ali Shojai
Here we shall find the green's function of the difference equation of loop quantum cosmology. To illustrate how to use it, we shall obtain an iterative solution for closed model an…
Variational Methods in Loop Quantum Cosmology
Fatimah Shojai, Ali Shojai
An action functional for the loop quantum cosmology difference equation is presented. It is shown that by guessing the general form of the solution and optimizing the action functi…
Static Einstein's Universe as a Quantum Solution of Causal Quantum Gravity
A. Shojai, F. Shojai, N. Dadhich
We shall in the framework of Bohmian quantum gravity show that it is possible to find a {\it pure} quantum state which leads to the static Einstein universe whose classical counter…
