2836. Spacetime from bits and cosmology from black holes

Mark Van Raamsdonk (UBC)

04/06/2019, 10:45

Theoretical Physics / Physique théorique (DTP-DPT)

Invited Speaker / Conférencier(ère) invité(e)

In this talk, I will discuss two applications of holographic duality for CFTs with boundaries (BCFTs). First, I will discuss how to describe smooth spacetimes via
multipart entangled states of many non-interacting BCFT systems. As a second
application, I will describe the construction of certain black hole
microstates for which the behind-the-horizon geometry can be deduced
explicitly. The...

2732. Boundary conditions, zero modes, and spacetime entropy

James Sully (University of British Columbia)

Theoretical Physics / Physique théorique (DTP-DPT)

Invited Speaker / Conférencier(ère) invité(e)

How do we describe the local Hilbert space of a continuum field theory? And does this have lessons to each us about the emergence of spacetime in AdS/CFT? I will describe how to define the Hilbert space of an interval in a CFT without turning to abstruse mathematics. For CFTs with a gravitational dual, this leads to a theory of gravitational membranes and new insights for understanding...

2487. Towards an Asymptotically Safe Standard Model

Dr Zhi-Wei Wang (University of Waterloo)

Theoretical Physics / Physique théorique (DTP-DPT)

Oral (Non-Student) / Orale (non-étudiant(e))

In this talk, I will discuss how to realize an asymptotically safe Standard Model by using the large number of flavours (N_f) techniques. This framework also opens the way to various safe extensions of the Standard Model. The first asymptotically safe Pati-Salam model and trinification model will also be discussed.

2501. Dark matter from Kalb-Ramond gauge symmetry

Oral (Non-Student) / Orale (non-étudiant(e))

We point out that the Kalb-Ramond field of string theory can induce electroweak dipole dark matter, although the dark matter constituents of the dipoles do not carry weak charges. We also show that the model is compatible with direct search constraints from electron recoils. However, the recoil cross sections are above the neutrino floor and should be testable in future experiments.
