Dimensionally Restricted Causal Sets
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...

Hydrodynamics and (Pre)Thermalization in Floquet Systems
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)...

milliQan - a new experiment for heavy milli-charged particles at the LHC
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...

Docker and Singularity
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...

Entanglement and extended conformal field theory
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...

New probes of fundamental physics: Utilising small-scale signatures in the Universe.
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...

Relativity, Particle localizability, and Entanglement
Can a relativistic quantum field theory be consistently described as a theory of localizable particles? There are many well-known obstructions to such a description. Here, we trace exactly how such...

Numerical approach to infrared conformality and associated dualities in 2+1 dimensions
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...

What is the landscape of natural language? Insights from a random language model
Many complex systems have a generative, or linguistic, aspect: life is written in the language of DNA; protein structure is written in a language of amino acids, and human endeavour...

Perimeter participates in #STRIKE4BLACKLIVES
On June 10, researchers and staff at Perimeter participated in the global science strike to support the ongoing Black Lives Matter movement and efforts to combat racism against Black, Indigenous...
