We then transform the problem into a second-order ordinary differential equation and thereby obtain the corresponding propagator. The result of ordinary quantum mechanics is recovered for vanishing minimal length parameter. 1. Introduction Inourpaper,wearegoingtocombinethesetwosubjects.

Proton lifetime, the main associated phenomenology of the noncommutative virtual black holes, has been studied: first in 4 dimensional spacetime and then generalized to D dimensions. The lifetime depends on θ and the number of spacetime dimensions such that it emphasizes on the measurement of proton lifetime as a potential probe for the micro-structure of spacetime.

Box 43, Egypt 4 Department of Physics, Faculty of Science, Benha University, Benha 13518, Egypt Received 16 November 2013; accepted 18 January 2014 Abstract: Recently, Verlinde proposed that gravity is an emergent phenomenon which originates from an entropic force. In this work, we extend Verlinde’s proposal to accommodate generalized uncertainty principles (GUP), which are suggested by some approaches to quantum gravity such as string theory, black hole physics and doubly special relativity (DSR). Using Verlinde’s proposal and two known models of GUPs, we obtain modifications to Newton’s law of gravitation as well as the Friedmann equation. Our modification to the Friedmann equation includes higher powers of the Hubble parameter which is used to obtain a cor- responding Raychaudhuri equation. Solving this equation, we obtain a leading Planck-scale correction to Friedmann-Robertson-Walker (FRW) solutions for the p = ωρ equation of state.

    ASPECTS OF QUANTUM GRAVITY AHMED FARAG ALI Master of Science, Benha University, 2008 A Thesis Submitted to the School of Graduate Studies of the University of Lethbridge in Partial Fulfilment of the Requirements for the Degree DOCTOR OF PHILOSOPHY Department of Physics and Astronomy University of Lethbridge LETHBRIDGE, ALBERTA, CANADA c Ahmed Farag Ali, 2012 Dedication To Ebtesam, Ibrahim, and my parents. iii Abstract We propose a Generalized Uncertainty Principle(GUP) consistent with String Theory, Black Hole Physics and Doubly Special Relativity. This modifies all quantum mechan- ical Hamiltonians and predicts quantum gravity corrections. We compute corrections to the Lamb shift, simple harmonic oscillator, Landau levels, and the tunneling cur- rent. When applied to an elementary particle, it suggests that the space must be quantized, and that all measurable lengths are quantized in units of a fundamental length. We investigated whether GUP can explain the violation of the equivalence principle at small length scales that was observed experimentally. We investigated the consequences of GUP on Liouville theorem. We examined GUP effect on post inflation preheating, and show that it predicts an increase or a decrease in parametric resonance and a change in particle production. The effect of GUP on the creation of black holes is investigated to justify the experimental results from the Large Hadron Collider. iv Acknowledgements First and foremost, I would like to express about my deep gratitude for my supervisor Dr. Saurya Das whose expertise and attention to both detail and the big picture, provided invaluable guidance for my research, all the while being so friendly and straightforward during our discussions.

    Challenges for ΛCDM : An update L. Perivolaropoulos1, ∗ and F. Skara1, y 1Department of Physics, University of Ioannina, 45110 Ioannina, Greece (Dated: May 20, 2021) A number of challenges of the standard ΛCDM model has been emerging during the past few years as the accuracy of cosmological observations improves. In this review we discuss in a unified manner many existing signals in cosmological and astrophysical data that appear to be in some tension (2σ or larger) with the standard ΛCDM model as defined by the Planck18 parameter values. In addition to the major well studied 5σ challenge of ΛCDM (the Hubble H0 crisis) and other well known tensions (the growth tension and the lensing amplitude AL anomaly), we discuss a wide range of other less discussed less-standard signals which appear at a lower statistical significance level than the H0 tension (also known as 'curiosities' in the data) which may also constitute hints towards new physics. For example such signals include cosmic dipoles (the fine structure constant α, velocity and quasar dipoles), CMB asymmetries, BAO Lyα tension, age of the Universe issues, the Lithium problem, small scale curiosities like the core-cusp and missing satellite problems, quasars Hubble diagram, oscillating short range gravity signals etc. The goal of this pedagogical review is to collectively present the current status of these signals and their level of significance, with emphasis to the Hubble crisis and refer to recent resources where more details can be found for each signal. We also briefly discuss possible theoretical approaches that can potentially explain the non-standard nature of some of these signals.
