Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, public outreach events such as talks from top scientists using video cameras installed in our lecture theatres.  Perimeter now has 7 formal presentation spaces for its many scientific conferences, seminars, workshops and educational outreach activities, all with advanced audio-visual technical capabilities. 

Recordings of events in these areas are all available and On-Demand from this Video Library and on Perimeter Institute Recorded Seminar Archive (PIRSA)PIRSA is a permanent, free, searchable, and citable archive of recorded seminars from relevant bodies in physics. This resource has been partially modelled after Cornell University's arXiv.org. 

Accessibly by anyone with internet, Perimeter aims to share the power and wonder of science with this free library.

Speaker(s): 

I will discuss how studying the gravitational effects of UV physics on large (astrophysical) scales precludes new mass scales in BSM physics beyond 600 GeV.

Speaker(s): 

We demonstrate that extremely long range correlations may develop in systems that start from equilibrium and are then rapidly cooled (or driven in other ways). Amongst other things, these correlations suggest a collapse of the viscosity data of glass formers. This collapse is found to be obeyed over 16 decades of relaxation times in experimental data on all known types of supercooled fluids.

Speaker(s): 

I outline a configuration in which the Standard Model can be embedded into an asymptotically safe gauge-Yukawa theory. The model can be though of as a minimal UV completion of the SM without gravity. I also discuss the remaining issues that need to be addressed for the scheme to be phenomenologically viable, and outline the different energy scales and possible signatures.

Speaker(s): 

I describe recent progress in classifying 5d N=1 field theories with interacting UV superconformal fixed points (i.e. 5d SCFTs). In the first part of the talk, I review a newly proposed catalog of candidate (simple) gauge theories which captures theories missed by prior field theoretic classification efforts. In the second part of the talk, I discuss a classification program for rank 1 and 2 5d SCFTs in terms of Calabi-Yau 3-folds, along with prospects for its extension to arbitrary rank.

Speaker(s): 

We present fundamental limits of axion and hidden-photon dark matter searches probing the electromagnetic coupling. These limits are informed by constraints on noise in phase-insensitive amplifiers, as well as constraints on impedance matching. We motivate the use of quantum-limited amplifiers for dark matter searches, in particular at low masses/frequencies, where they provide a substantial enhancement due to sensitivity outside of the detector bandwidth. We discuss the role of priors, e.g.

Speaker(s): 

I summarise the state-of-the-art in our understanding of fundamental interactions and will set the stage for present and future studies and phenomenological applications.

Thursday May 31, 2018
Speaker(s): 

I suggest a minimal practical formal structure for a more fundamental theory than the Standard Model + GR and review a mechanism that produces such a structure.  The proposed mechanism has possibilities of producing non-canonical phenomena in SU(2) and SU(3) gauge theories which might allow conditional predictions that can be tested.
