Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, and public outreach events 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 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.

I will describe a new collider object we have termed emerging jets.

These can arise when there is a confining dark sector connected to the

Standard Model by a TeV scale mediator, a scenario that is well

motivated by dark matter considerations. The signature of an emerging

jet is O(10) displaced vertices inside the jet each with different

impact parameter, and a small number of prompt tracks. I will describe

strategies that can be used to discover emerging jets even if they

Holographic duality is a duality between gravitational systems and non-gravitational systems. In this talk, I will propose a different approach for understanding holographic duality named as the exact holographic mapping. The key idea of this approach can be summarized by two points: 1) The bulk theory and boundary theory are related by a unitary mapping in the Hilbert space. 2) Space-time geometry is determined by the structure of correlations and quantum entanglement in a quantum state. When applied to lattice systems, the holographic mapping is defined by a unitary tensor network.

I will describe a new proposal for defining the holographic

entanglement entropy at subleading orders in N (on the boundary) or

hbar (in the bulk). This involves a new concept of "quantum extremal

surfaces" defined as the surface which extremizes the sum of the area

and the bulk entanglement entropy. This conjecture reduces to

previous conjectures in suitable limits, and satisfies some nontrivial

consistency checks. Based on arXiv:1408.3203
