Probing string theory through cosmological observations?

Robert Brandenberger McGill University - Department of Physics

November 08, 2007
PIRSA:07110053

Quantum Gravity

If string theory is the correct theory which unifies gravity with the other forces of nature at a quantum level, it should determine the evolution of the earliest stages of the universe. I will discuss how stringy signatures of this early phase may be visible in current cosmological observations.

Particle Physics

"International researchers at the Large Hadron Collider (LHC), in Geneva, Switzerland, will soon embark on one of science's greatest adventures. With its very high energy, previously seen only in cosmic rays, the particle collider will probe the inner structure of matter at distances ten times smaller than any previous experiments. The LHC will address many of the mysteries surrounding the smallest particles of matter. It may also pierce secrets that the Universe has hidden since the early stages of the Big Bang, such as the nature of dark matter and the origin of matter itself. This will be the largest scientific experiment ever attempted and the complex international efforts to bring the 27km-long machine to life, including Canada’s involvement, will also be explained."

About John EllisBorn in London on July 1st, 1946, Ellis grew up in Potters Bar, a suburb that some Londoners used to regard as the northern boundary of civilization. It was there, at around the age of 12, he decided to become a physicist – largely due to the interesting science books he read at the local library. Ellis obtained his BA and PHD from Cambridge University where he studied mathematics and theoretical physics. Following a year at the Stanford Linear Accelerator Center and an additional year at the California Institute of Technology as a research associate, Ellis joined CERN in 1973 and became leader of the Theory Division for six years. Currently, he is a senior staff member. Ellis is also an advisor on CERN’s relations with non-Member States.Ellis has published over 700 scientific articles in particle physics and related areas of cosmology and astrophysics. His research interests include the possible experimental consequences and tests of new theoretical ideas such as gauge theories of strong and electroweak interactions, grand unified theories, supersymmetry, and string theory. He was elected a Fellow of the Royal Society in 1985, and was awarded the Dirac Medal of the Institute of Physics in 2005. Ellis is also responsible for popularizing the term “Theory of Everything” in an article published in the journal Nature in 1986.

About Robert S. OrrProfessor Orr was born in Iran, and grew up in Scotland and South Wales. His father and uncles were all engineers in the ship building industry. His interest in physics was sparked early in his childhood by trying to make sense of his father’s textbooks. “Ever since I was a child, I took things apart to see how they worked” says Orr. “Doing that with matter is the ultimate challenge."

At present he is a Professor in the Department of Physics at the University of Toronto. He was NSERC Principal Investigator for ATLAS Canada from 1994 to 2007. ATLAS is a detector within the LHC at CERN. Orr earned his B.Sc. and Ph.D. at Imperial College, University of London, UK, and was a Post Doctoral Researcher at Rutherford Laboratory, also in the UK, as well as at the University of Wisconsin, Madison, USA. From 1974 to 1981 he was a CERN Fellow and Staff Physicist. He came to Canada in 1981 as an Institute of Particle Physics Research Scientist, and became a member of the faculty at the University of Toronto in 1989. Orr has worked at many of the world’s particle physics labs in the USA, Germany and Japan. He has a particular interest in the application of large scale computing clusters in this field, and in the development of new finds of detection devices.
Phenomenology of Discrete Space: Possible Tests

Quantum Gravity

I will discuss possible tests of the grainularity of space including modified dispersion relations in the formation of white dwarfs and neutron stars and constraints on a stochastic direction field from atomic system tests.
Symmetry and global independence in classical and quantum theories

Quantum Information

Renner\'s global quantum de Finetti theorem establishes that if the state of a quantum system is invariant under permutations of its systems, then almost all of its subsystems are almost in the same state and independent of each other. Motivated by this result, we show that the most straightforward classical analogue of Renner\'s theorem is false. Joint work with Matthias Christandl (Cambridge).
Gravitational collapse in quantum gravity

Viqar Husain University of New Brunswick

November 07, 2007
PIRSA:07110050

Quantum Gravity

I will describe work aimed at understanding the dynamics of gravitational collapse in a fully quantum setting. Its emphasis is on the role played by fundamental discreteness. The approach used suggests modifications of a black hole\'s mass loss rate and thermodynamical properties. Numerical simulations of collapse with quantum gravity corrections indicate that black holes form with a mass gap.
Topological Quantum Computation: anyons, quantum symmetries and topological order

Sander Bais Universiteit van Amsterdam

November 07, 2007
PIRSA:07110002

This will be an introductory talk about Topological Quantum Computation. TQC is attractive because it is intrinsicaly decoherence free. We introduce the basic notions, such as non abelian anyons, quantum symmetries and topological order. A topologically ordered phase is a gapped phase in which the basic degrees of freedom are of a topological nature (denoted as anyons), charactetized by their fusion and braiding properties. If time permits possible implementations based on Quantum Hall systems will be discussed as well.

Phenomenology of black holes in particle colliders and cosmic ray showers

Marco Cavaglia University of Mississippi

November 06, 2007
PIRSA:07110047

Quantum Gravity

If large extra dimensions exist, microscopic black holes may be created in TeV particle colliders and in Earth\'s atmosphere by the collisions of ultrahigh-energy cosmic rays with atmospheric nuclei. The decay of these black holes could soon be observed at the Large Hadron Collider or the Pierre Auger Observatory. Monte Carlo codes have been developed to simulate these events. In this talk I will introduce two of these codes (CATFISH for the LHC and GROKE for the PAO), and discuss how mini black holes can be distinguished from standard model or susy events.
Towards a Phenomenology of Quantum Gravity?

John Ellis European Organization for Nuclear Research (CERN)

November 06, 2007
PIRSA:07110046

Quantum Gravity

This talk will review proposed tests of ideas about quantum gravity, including searches for quantum decoherence, probes of the possible energy-dependence of the velocity of light, and the nature of vacuum energy. Motivations will be drawn from a non-critical string theory framework.
