Dissertation Defense: David Stewart, Yale University, "Jet to Event Activity Correlations in Small System Collisions at STAR"

Heavy ion collisions at the LHC and RHIC produce a quark gluon plasma (QGP), in which quarks and gluons are deconfined into an extended medium. This “fourth phase” of matter is also believed to have been the first material phase of the universe following the Big Bang. In experiment, high energy partons scatter at short time scales and may subsequently lose energy, or are “quenched”, via interactions with the QGP.

"I Prove a Theorem and the House Expands: Geometry and Poetry," Virtual Talk by Jordan Ellenberg

We are delighted that famed author and mathematician Jordan Ellenberg will be joining us for a virtual talk this semester. In his words, our speaker wrote a book about geometry and found himself, surprisingly, constantly talking about poetry.

Inference Project Talk and Discussion: The Inference of Nature: Cause and Effect in Molecular Biology

Theoretical approaches have always played an important role in biology, dating back to Mendel’s peas. In today’s era of genomics and big data in biology, statistical and computational tools are even more vital for biologists seeking to infer causation in living systems. To illustrate the range of methods, from modelling to machine learning, and how they contribute to understanding biological mechanisms, Dr. Teichmann will pick examples from some of the core problems her lab has been investigating as case studies.

Inference Project Talk: "No Cause for Concern: Indefinite Causal Ordering as a Tool for Understanding Entanglement"

Understanding the sorts of explanations and inferences that causal processes countenance is of course of great interest to philosophers and physicists (among others). But what can be said about physical processes that fail to exhibit classical causal structure? Indefinite causal ordering among events made possible by quantum correlations has become a fruitful arena of study recently, yielding new insights for quantum computing and communication, approaches to quantum gravity, and even for foundational issues in quantum mechanics.
