Numerical approach to infrared conformality and associated dualities in 2+1 dimensions
Nikhil Karthik - Brookhaven National Laboratory
QFTs in 2+1 dimensions are powerful systems to understand the emergence of mass-gap and particle spectrum in QCD-like theories that describe our 3+1 dimensional world. Recently, these 2+1 dimensional systems have attracted even more attention due to conjectured dualities between seemingly very…
New probes of fundamental physics: Utilising small-scale signatures in the Universe.
Selim Hotinli - Perimeter Institute for Theoretical Physics
The influx of new and high-quality cosmological data from upcoming cosmic microwave background (CMB) and large-scale structure surveys will provide unique and exciting opportunities to study the fundamental constituents of the Universe in the upcoming few years. In particular, measurements of second…
Entanglement and extended conformal field theory
Gabriel Wong - Harvard University
Defining entanglement in a continuum field theory is a subtle challenge, because the Hilbert space does not naively factorize into local products. For gauge theories, the problem arises from the gauss law constraint, and it can be resolved by an extension of the Hilbert space which introduces edge…
milliQan - a new experiment for heavy milli-charged particles at the LHC
Andrew Haas - New York University (NYU)
milliQan is a proposed search for milli-charged particles produced at the LHC with expected sensitivity to charges of between 0.1e and 0.001e for masses in 0.1 - 100 GeV range. The proposed detector is an array of 4 stacks of 60 cm long plastic scintillator arrays read out by PMTs. It will be…
Docker and Singularity
Dustin Lang - Perimeter Institute for Theoretical Physics
Docker provides "containerization" for software -- a way to package up a piece of software and all its dependencies, so that it can run the same way on different computers. It is a promising technology for scientists, both for reproducibility, ease of collaboration, and for running software on…
Hydrodynamics and (Pre)Thermalization in Floquet Systems
Roger Mong - University of Pittsburgh
A tremendous amount of recent attention has focused on characterizing the dynamical properties of periodically driven many-body systems. Here, we use a novel numerical tool termed ‘density matrix truncation’ (DMT) to investigate the long-time dynamics of large-scale Floquet systems. By implementing…
Dimensionally Restricted Causal Sets
William Cunningham - Perimeter Institute for Theoretical Physics
We study dimensionally restricted non-perturbative causal set quantum dynamics in two and three spacetime dimensions with non-trivial global spatial topology. The causal set sample space is generated from causal embeddings into latticisations of flat background spacetimes with global spatial…
3D Mirror Symmetry and HOMFLY-PT Homology
Tudor Dimofte - University of Edinburgh
A recent construction of HOMFLY-PT knot homology by Oblomkov-Rozansky has its physical origin in “B-twisted” 3D N=4 gauge theory, with adjoint and fundamental matter. Mathematically, the construction uses certain categories of matrix factorization. We apply 3D Mirror Symmetry to identify an A…
Real-time dynamics of plasma balls in a confining background
Pau Figueras - Queen Mary University of London
Black holes in the background of the AdS soliton are, according to the gauge/gravity correspondence, dual to droplets of deconfined plasma surrounded by a confining vacuum. In this talk I will present, for the first time, the real time dynamics of finite energy black holes in these backgrounds. We…

Toy Models of Holographic Duality between local Hamiltonians
Tamara Kohler - Complutense University of Madrid
Holographic quantum error correcting codes (HQECC) have been proposed as toy models for the AdS/CFT correspondence, and exhibit many of the features of the duality. HQECC give a mapping of states and observables. However, they do not map local bulk Hamiltonians to local Hamiltonians on the boundary…
