Bianchi IX and VIII Quantum Cosmology with a Cosmological Constant, Aligned Electromagnetic Field, and Scalar Field
Daniel Berkowitz
We investigate the quantum cosmologies of the Bianchi IX and VIII models when a cosmological constant, aligned electromagnetic field and free scalar field are present. The conserve…
Infrared Generalized Uncertainty Principles Applied To LRS Bianchi I Quantum Cosmology
Daniel Berkowitz
We propose two higher order generalized uncertainty principles(GUPs) which predict a minimum uncertainty in momentum and apply the deformations that they entail of the Heisenberg a…
Towards Uncovering Generic Effects Of Matter Sources In Anisotropic Quantum Cosmologies Via Taub Models
Daniel Berkowitz
We solve the Wheeler DeWitt equation for the Taub models in closed form when both a cosmological constant and an electromagnetic field are present. In doing so, we examine the 'exc…
Bianchi II and VII Models Revisited Via The Euclidean-Signature Semi Classical Method
Daniel Berkowitz
We apply in a novel fashion a modified semi-classical method to the Bianchi II and VII models when a cosmological constant, aligned electromagnetic field and stiff matter a…
Closed Form Solutions For The Quantum LRS Bianchi IX and VIII Wheeler DeWitt Equations For An Arbitrary Hartle-Hawking Ordering Parameter
Daniel Berkowitz
In this paper we present the quantum LRS Bianchi IX models or, as they may be better known, the Taub-NUT models in addition to the quantum LRS Bianchi VIII models, both coupled to…
New Solutions To The Bianchi VIII Wheeler DeWitt Equation And Leading Order Solutions For 0 And A Primordial Magnetic Field
Daniel Berkowitz
New non trivial solutions to the Lorentzian-signature symmetry reduced Bianchi VIII Wheeler DeWitt equation for Hartle Hawking ordering parameters are obtained u…
