New Horizons In Fundamental Physics
This course is an introduction to some of the most exciting ideas in fundamental physics. The topics are chosen to represent areas of research currently conducted at Perimeter Institute. Each topic will be discussed for one or two weeks and will be lectured by a leading young researcher in each field. From deep conceptual issues on the meaning of quantum theory, passing through very sophisticated theories like string theory and loop quantum gravity all the way to cosmology and quantum information theory, this course is a challenging intellectual adventure. -
Special Topics in Physics
This course will provide an introduction to current research on the problem of time in quantum gravity and cosmology. This is one of the key problems that any successful quantum theory of gravity must solve. Different approaches to quantum gravity assume different answers to fundamental questions such as whether time is emergent or not, whether causality is emergent or not, and what is an observable in a theory of gravity. These problems have aspects which are technical as well as conceptual and philosophical aspects and we will discuss them all as well as their inter-relations. The course will begin with an introduction to the canonical formulation of general relativity and related dynamical systems. We will then study the standard material on the Hamiltonian quantization of general relativity and related time reparametrization invariant systems. This gives us the technical setting in which the problem of time is usually encountered in the contemporary literature on quantum gravity and quantum cosmology. Following this physical introduction we will read the key texts from the history of physics and philosophy concerning the meaning of time, such as Newton, Leibniz, Mach, Einstein etc. This will be followed by readings of papers and books from contemporary sources on this issue by physicists and philosophers. We will focus on two opposite views, the idea that time is emergent in quantum cosmology and the opposing idea that time is fundamental and is perhaps the only aspect of our macroscopic reality that is not emergent. -

Quantum Information Theory in Quantum Gravity - 2007
December 8-10, 2007 Canadian Mathematical Society Meeting, London, Ontario (December 8) Perimeter Institute (December 9,10) There is presently a high level of interest towards quantum information theory, and related fields such as quantum computing and cryptography. While there remain many key issues to overcome, these fields have the potential for far-reaching applications. One set of fundamental applications that has recently emerged is to quantum gravity. There is now a variety of different connections that have been explored. Researchers in this area come from different backgrounds and the primary purpose of the workshop is to meet and learn of each other's work and foster discussions. Some of the connections between quantum gravity and quantum information theory have now risen to a more formal mathematical level. Reflecting this, Day 1 of the workshop (Saturday, December 8) will be held as a Special Session at the Winter 2007 Meeting of the Canadian Mathematical Society in London, Ontario (http://www.cms.math.ca/Events/winter07/). Seth Lloyd will deliver a plenary address to the CMS Meeting on that day. The schedule of Days 2 and 3 at the Perimeter Institute will allow plenty of time for discussions in an informal setting. Some of the topics we will discuss are: causality and quantum dynamics in quantum gravity, quantum reference frames, topological order in quantum gravity, information bounds and information loss in quantum gravity. -
