Toward matter dynamics in spin foam quantum gravity
Masooma Ali, Sebastian Steinhaus
Any approach to pure quantum gravity must eventually face the question of coupling quantum matter to the theory. In the past, several ways of coupling matter to spin foam quantum g…
Monte Carlo simulation of cosmologies with dust
Masooma Ali, Syed Moeez Hassan, Viqar Husain
The quantum theory of the Friedmann cosmological model with dust and cosmological constant () is not exactly solvable analytically. We apply Path Integral Monte Carlo (PIMC) tec…
The Universe as an Oscillator
Masooma Ali, Syed Moeez Hassan, Viqar Husain
We apply the idea of using a matter time gauge in quantum gravity to quantum cosmology. For the Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe with dust and cosmological const…
Natural Inflation from Polymer Quantization
Masooma Ali, Sanjeev S. Seahra
We study the polymer quantization of a homogeneous massive scalar field in the early universe using a prescription inequivalent to those previously appearing in the literature. Spe…
Mixmaster dynamics in the dust time gauge
Masooma Ali, Viqar Husain
We study the Hamiltonian dynamics of the dust-Bianchi IX universe in dust time gauge. This model has three physical metric degrees of freedom, with evolution determined by a time-i…
Linearized gravity with matter time
Masooma Ali, Viqar Husain, Shohreh Rahmati +1
We study general relativity with pressureless dust in the canonical formulation, with the dust field chosen as a matter-time gauge. The resulting theory has three physical degrees…
