Transient de Sitter and Quasi de Sitter States in SO(32) and E_8 x E_8 Heterotic String Theories
Keshav Dasgupta, Suddhasattwa Brahma, Bohdan Kulinich +3
One of the long-standing puzzles in string theory has been on the existence of a four-dimensional de Sitter and quasi de Sitter configurations, the latter being defined with a temp…
Constrained Dynamics on an Ellipse
Akshay Chaturvedi, Pichai Ramadevi
We first review the application of Dirac's method to the dynamics of a classical particle constrained to a circle and its subsequent quantization. Then, we extend the analysis to a…
Colored Jones Polynomials and the Volume Conjecture
Mark Hughes, Vishnu Jejjala, P. Ramadevi +2
Using the vertex model approach for braid representations, we compute polynomials for spin-1 placed on hyperbolic knots up to 15 crossings. These polynomials are referred to as 3-c…
de Sitter Excited State in Heterotic E_8 x E_8 Theory
Suddhasattwa Brahma, Keshav Dasgupta, Bohdan Kulinich +3
We devise a novel duality sequence to study late-time cosmology in the heterotic E_8 x E_8 setup of Horava and Witten with dynamical walls that are moving towards each other. Surpr…
