Phenomenology of a massive quantum field in a cosmological quantum spacetime
Saeed Rastgoo, Yaser Tavakoli, Julio C. Fabris
We revisit the quantum theory of a massive, minimally coupled scalar field, propagating on the Planck-era isotropic cosmological quantum spacetime which transitions to a classical…
Constraint Lie algebra and local physical Hamiltonian for a generic 2D dilatonic model
Alejandro Corichi, Asieh Karami, Saeed Rastgoo +1
We consider a class of two dimensional dilatonic models, and revisit them from the perspective of a new set of "polar type" variables. These are motivated by recently defined varia…
Polymer quantization and the saddle point approximation of partition functions
Hugo A. Morales-Técotl, Daniel H. Orozco-Borunda, Saeed Rastgoo
The saddle point approximation of the path integral partition functions is an important way of deriving the thermodynamical properties of black holes. However, there are certain bl…
The Structurally Dynamic Cellular Network and Quantum Graphity Approaches to Quantum Gravity and Quantum Geometry - A Review and Comparison
Manfred Requardt, Saeed Rastgoo
Starting from the working hypothesis that both physics and the corresponding mathematics and in particular geometry have to be described by means of discrete concepts on the Planck…
