Black Remnants from T-Duality
Behnam Pourhassan, Salman Sajad Wani, Mir Faizal
In this paper, we will analyze the physical consequences of black remnants, which form due to non-perturbative string theoretical effects. These non-perturbative effects occur due…
Operator Ordering Ambiguity and Third Quantization
Yoshiaki Ohkuwa, Yasuo Ezawa, Mir Faizal
In this paper, we will constrain the operator ordering ambiguity of Wheeler-DeWitt equation by analyzing the quantum fluctuations in the universe. This will be done using a third q…
Constraints and Horizons for de Sitter with Extra Dimensions
Saurya Das, S. Shajidul Haque, Bret Underwood
In order for spacetimes with static extra dimensions to have 4-dimensional de Sitter expansion they must have at least positive curvature, warping sourced by the 4-d expansion, or…
Quantum corrections to a finite temperature BIon
Behnam Pourhassan, Sanjib Dey, Sumeet Chougule +1
In this paper, we will analyze a finite temperature BIon, which is a finite temperature brane-anti-brane wormhole configuration. We will analyze the quantum fluctuations to this BI…
Low Energy Consequences of Loop Quantum Gravity
Salman Sajad Wani, Behnam Pourhassan, Mir Faizal +1
As the loop quantum gravity is based on polymer quantization, we will argue that the polymer length (like string length) can be several orders larger than the Planck length, and th…
Charged scalar quasi-normal modes for higher-dimensional Born-Infeld dilatonic black holes with Lifshitz scaling
S. Sedigheh Hashemi, Mahdi Kord Zangeneh, Mir Faizal
We study quasi-normal modes for a higher dimensional black hole with Lifshitz scaling, as these quasi-normal modes can be used to test Lifshitz models with large extra dimensions.…
