WIDG Seminar, London Cooper-Troendle, Yale, “Extraction of an Inclusive Muon Neutrino Charged Current Differential Cross Section at MicroBooNE”

The MicroBooNE detector is a Liquid Argon Time Projection Chamber (LArTPC) located along the Booster Neutrino Beam (BNB) at Fermilab. One of its key physics goals is the measurement of neutrino-Argon interaction cross sections. Due to the detector’s fully active volume as well as its capability to offer a high-efficiency neutrino event selection, MicroBooNE is well suited produce the first ever triple-differential neutrino-Argon cross section.

Particle Theory Seminar: Pedro Liendo, DESY, “Bootstrapping holographic defect correlators”

We apply analytic bootstrap techniques to study correlators of local operators in the presence of an extended object or “defect”. After reviewing the general setup, we focus on N=4 SYM at strong coupling.

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.

Condensed Matter Theory Seminar: Xiaochuan Wu, UCSB, “A construction of exotic metal and metal-insulator transition”

Abstract: The charge resistivity/conductivity can take universal values in various scenarios of two-dimensional condensed matter systems. Well-known examples of universal resistivity include 2+1d quantum critical points, (fractional) quantum Hall effects, the criterion of two-dimensional “bad metal”, and the universal resistivity jump predicted at the interaction-driven metal-insulator transition.

Condensed Matter Theory Seminar: Yves Kwan, University of Oxford, “Kekulé spirals in twisted bilayer graphene"

Abstract: Intense experimental efforts over the past few years have uncovered a rich phenomenology in magic-angle twisted bilayer graphene (TBG). The search for a unifying theoretical framework is complicated by the variability of observations between different samples, which is often attributed to perturbations beyond the pristine limit. Among these is strain, which has been demonstrated via scanning tunnelling experiments to be ubiquitous in TBG devices.

Condensed Matter Theory Seminar: Benjamin Remez, University of Cambridge, “Collective Phenomena in Excitonic Matter”

Abstract: Bound electron-hole pairs, known as excitons, let us realize a plethora of bosonic correlated phases in the solid state. In recent years, the ability to manipulate excitonic states of matter has advanced significantly thanks to novel materials, most notably transition metal chalcogenides such as Ta2NiSe5, TiSe2, and WS2/MoS2 heterobilayers, providing us new access to this rich phase diagram.

The Kimball Smith Series, Sasha Brown, Marynel Vázquez, Wendall Wallach, "AI Ethics on the Global Stage"

AI Ethics on the Global Stage
Join us on Tuesday, November 30th, 2021 at 4 PM in Watson Center (WTS) A74 for a moderated panel followed by small group discussions about artificial intelligence in the contemporary global climate.
The panel will feature experts Wendall Wallach (Interdisciplinary Center for Bioethics), Sasha Brown (World Fellows Program) and Marynel Vázquez (Interactive Machines Group).
Attendees will learn about how AI works and is applied, key recent innovations, current ethical questions, and AI’s impact on the global economy and politics.

WIDG Seminar, Roberto Soleti, Lawrence Berkeley National Laboratory, “DuNE Near Detector”

In-person attendance will be capped at 20 people on a first-come, first-served basis, according to the current Yale policies.

Inference Project Virtual Talk: "Bias in Algorithms"

Artificial algorithms are increasingly being deployed to inform, endorse, and govern various aspects of today’s society. Their reach includes the domains of hiring, lending, medicine, criminal justice, insurance, allocation of public services, social and business interactions, and the dissemination of information and news.

Particle Theory Seminar: Hirosi Ooguri, California Institute of Technology, "Symmetry in QFT and Gravity"

Speaker: Hirosi Ooguri (Caltech)
Title: Symmetry in QFT and Gravity
Abstract: I will review aspects of symmetry in quantum field theory and combine them with the AdS/CFT correspondence to derive constraints on symmetry in quantum gravity. The quantum gravity constraints to be discussed include the no-go theorem on global symmetry, the completeness of gauge charges, and the decomposition of high energy states into gauge group representations.
