On Dark Energy and Quantum Gravity
Per Berglund, Tristan Hubsch, Djordje Minic
Realizing dark energy and the observed de Sitter spacetime in quantum gravity has proven to be obstructed in most every usual approach. We argue that additional degrees of freedom…
Dark Energy and String Theory
Per Berglund, Tristan Hübsch, Djordje Minic
A radiatively stable de Sitter spacetime is constructed by considering an intrinsically non-commutative and generalized-geometric formulation of string theory, which is related to…
Spekkens' Toy Model, Finite Field Quantum Mechanics, and the Role of Linearity
Lay Nam Chang, Djordje Minic, Tatsu Takeuchi
We map Spekkens' toy model to a quantum mechanics defined over the finite field . This allows us to define arbitrary linear combinations of the epistemic states in th…
On Stringy de Sitter Spacetimes
Per Berglund, Tristan Hübsch, Djordje Minic
We reexamine a family of models with a 3+1-dimensional de Sitter spacetime obtained in the standard tree-level low-energy limit of string theory with a non-trivial anisotropic axio…
