Causality at the Intersection of Simulation, Inference, Science, and Learning

The sciences are replete with high-fidelity simulators: computational manifestations of causal, mechanistic models. Ironically, while these simulators provide our highest-fidelity physical models, they are not well suited for inferring properties of the model from data. Professor Kyle Cranmer of New York University will describe the emerging area of simulation-based inference and describe how machine learning is being brought to bear on these challenging problems.

EHS Orientation for Wright Lab Shop Users - Spring 2022

Wright Lab will host 1-hour Environmental Health and Safety (EHS) Shop Orientations. The EHS shop orientation is offered each semester and is required to be taken once by anyone who would like to gain access and make use of the research and teaching shops at Wright Lab.
For more information on the shop facilities at Wright Lab see: https://wlab.yale.edu/facilities

WIDG Seminar, Glenn Richardson, Yale, “Charge Reconstruction and Simulation in the nEXO Experiment”

Abstract: nEXO is a proposed tonne scale liquid xenon time projection chamber which plans to search for the neutrinoless double beta decay (0vbb) of Xe-136. 0vbb is a hypothetical nuclear process in which two neutrons decay into two protons and two electrons, with the notable absence of any neutrinos. Discovery of this hypothetical phenomena would help answer several questions concerning the mass of the neutrino, such as their Majorana nature. nEXO’s proposed detector design would allow it to search for this interaction with a half-life sensitivity greater than 10^{28} yrs.

NPA Seminar, Steven Murray, Arizona State University, "Forward Modelling Interferometric Observations of the EoR"

Abstract: 21cm observations of the Cosmic Dawn and Epoch of Reionization, via intensity mapping at z>6, offer a unique and exciting probe into the physics of stellar and galaxy formation and even cosmology. A range of instruments across the globe, including the highly targeted HERA experiment, are currently amassing a wealth of data – in which is buried the signature of the birth of the first stars.

NPA Seminar, Akash Dixit, University of Chicago, "Searching for dark matter with superconducting qubits"

Abstract: Detection mechanisms for low mass bosonic dark matter candidates, such the axion or hidden photon, leverage potential interactions with electromagnetic fields, whereby the dark matter (of unknown mass) on rare occasion converts into a single photon. Current dark matter searches operating at microwave frequencies use a resonant cavity to coherently accumulate the field sourced by the dark matter and a near standard quantum limited (SQL) linear amplifier to read out the cavity signal.

NPA Seminar, Simon Foreman, Perimeter Institute, "Detection of Cosmological 21cm Emission with CHIME"

Abstract: Intensity mapping of redshifted 21cm emission from neutral hydrogen holds great promise for learning about cosmology, as it provides an efficient way to map large volumes of the universe without the need to characterize individual luminous sources. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a cylinder telescope located in Western Canada that was custom-built for this purpose, and that has collected several hundred days’ worth of data since it reached full observational capacity in late 2018.

The Neuroscience of Human Decisions: Mapping as Knowing Lecture Series Virtual Talk

Mariano Sigman is one of the most outstanding neuroscientists in the world, with over 150 publications in the most prestigious scientific journals. He is also passionate about experimentation and has worked with magicians, chess masters, musicians, athletes and visual artists to bring his knowledge of neuroscience to different aspects of human culture and apply it in different contexts. He has participated twice (2016 and 2017) in the TED global events in Vancouver, the second with Dan Ariely.

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.
