August 1, 2009 and Beyond Statement of Objectives for Next Year and Future 53-54 1 Statement of Objectives Introduction In 2008-9, the Institute achieved many important objectives of its mandate, which is to advance pure research in specific areas of theoretical physics, and to provide high quality outreach programs that educate and inspire the Canadian public, particularly young people, about the importance of basic research, discovery and innovation. Full details are provided in the body of the report below, but it is worth highlighting several major milestones. These include: In October 2008, Prof. Neil Turok officially became Director of Perimeter Institute. Dr. Turok brings outstanding credentials both as a scientist and as a visionary leader, with the ability and ambition to position PI among the best theoretical physics research institutes in the world. Throughout the last year, Perimeter Institute‘s growing reputation and targeted recruitment activities led to an increased number of scientific visitors, and rapid growth of its research community.

Dark Matter with Density-dependent Interactions Abstract The decay and annihilation cross sections of dark matter particles may depend on the value of a chameleonic scalar field that both evolves cosmologically and takes different values depending on the local matter density. This possibility introduces a separation between the physics relevant for freeze-out and that responsible for dynamics and detection in the late universe. We investigate how such dark sector interactions might be implemented in a particle physics Lagrangian and consider how current and upcoming observations and experiments bound such dark matter candidates. A specific simple model allows for an increase in the annihilation cross section by a factor of 106 between freeze-out and today, while more complicated models should also allow for scattering cross sections near the astrophysical bounds. -
Exotic Acceleration Mechanisms
Exotic Acceleration Mechanisms Mark Trodden U.Penn/Syracuse University Stanford Linear Accelerator Center SLAC Summer Institute 8/11/2008 Outline • Introduction. • A Disclaimer • Topological Defects (I’ll focus on these) - Overview - Classification and Formation - Dynamics - Examples - cusps, superconducting strings, cosmic necklaces • Superheavy Dark Matter (Briefly) - Generation - Preheating - Annihilations and Decays • Lorentz Violations (Even more briefly) • Summary and Conclusions Mark Trodden, U.Penn/Syracuse University SLAC Summer Institute Exotic Acceleration Mechanisms Stanford Linear Accelerator Center, 8/11/2008 Disclaimer • I am not a cosmic ray physicist! • I don’t write papers on this topic! • I really am not a cosmic ray expert in any way! • Honestly! But ... • My particular topic isn’t really about cosmic rays. • It is really about the types of beyond the standard model physics, (both particle physics and cosmology) that can give rise to tremendously high particles in today’s universe. • I do know a bit about that. • Hopefully! Mark Trodden, U.Penn/Syracuse University SLAC Summer Institute Exotic Acceleration Mechanisms Stanford Linear Accelerator Center, 8/11/2008 Main Point We seek extremely high energy particles in today’s universe There are really two broad ways in which one can imagine getting these • Astrophysics: Interacting matter in today’s universe conspires to accelerate particles to high velocities. • Cosmology: Here there is a problem - the universe cools! No simple equilibrium process leads to high energy particles being produced cosmologically in today’s universe. • To get around this need to somehow “preserve” some of the early, high-energy universe, and then persuade it to give up its energy as highly-accelerated particles today. -

Causal Sets Dynamics: Review & Outlook
NEB 15 – Recent Developments in Gravity IOP Publishing Journal of Physics: Conference Series 453 (2013) 012023 doi:10.1088/1742-6596/453/1/012023 Causal Sets Dynamics: Review & Outlook Petros Wallden 1. University of Athens, Physics Department, Nuclear & Particle Physics Section, Panepistimiopolis 157-71, Ilissia Athens, Greece 2. Technological Educational Institute (TEI) of Chalkida, General Science Department, Psahna-34400, Greece E-mail: [email protected], [email protected] Abstract. Causal sets is an approach to quantum gravity, where spacetime is replaced by a causal set. It is fundamentally discrete, and the causal relations between spacetime elements is the only structure that remains. A complete theory should have (i) kinematics (ii) dynamics and (iii) phenomenology. In this contribution we will explore the dynamical part of the theory, focusing on recent developments. We will analyse (a) classical dynamics of the causal set, (b) quantum dynamics of matter and fields on a classical causal set and finally (c) quantum dynamics of the causal set. 1. Motivation Constructing a quantum theory of gravity, consistent, widely accepted and confirmed by experiments is probably the most important open problem in current theoretical physics. The mathematical and conceptual difficulties that arise, suggest we may need to abandon some of the a-priori assumptions we make about nature. This is essentially done in all approaches to quantum gravity. In this contribution, we examine the causal sets approach (first appeared in [1] while in [2] some reviews can be found). It is the nature of spacetime as a differential manifold with a Lorentzian metric on it that is questioned in this approach.
