Kimball Smith Series: The Science and Ethics of Autonomous Warfare

Join us for a moderated panel followed by small group discussions on the topic of autonomy and artificial intelligence in warfare. The panel will feature Ian Abraham (Assistant Professor of Mechanical Engineering & Materials Science at Yale and leader of the Intelligent Autonomy Lab) and Michael Butera (Policy Advisor in the Bureau of Political-Military Affairs at the U.S. Department of State).

From Cross Campus to West Campus to Science Hill: The Yale Ancient Pharmacology Program

Building upon two decades of edge-finding archaeological research, the Yale Ancient Pharmacology Program continues to refine a transdisciplinary approach that seamlessly blends ethnography, materiality, and technology. Nucleating at the Yale Peabody Museum has allowed YAPP to work across its divisions and vast collections to push our knowledge of ancient organic materials through the fusion of ethnohistory, phytochemistry, and data science.

Dissertation Defense: Tong Liu, Yale University, "Inclusive Hadron Yield Analysis in Small and Mid-sized Collision Systems at sqrt(s_NN)=200 GeV at STAR"

At extremely high temperature and energy density, the quarks and gluons form a novel state of matter called the Quark-Gluon Plasma (QGP). The QGP has been widely studied via relativistic heavy ion collisions in large collision systems like Au+Au and Pb+Pb. However, whether the QGP exists in small systems like p+Au, and the dependence of QGP production on the collision system size are still open questions. One way to study the QGP properties is by using proxies of high energy partons, which are created in the initial stages of the collisions, and fragment into hadrons in the final state.

Dissertation Defense: Sumita Ghosh, Yale University, "Harnessing HAYSTAC for Hidden Photons and Advancing Rydberg Atom-based Axion Detection"

Dark matter is the name that we give to the 85% of matter in the universe that interacts via gravity but negligibly with any of the other known forces. One compelling model for dark matter is the axion, as it simultaneously solves the existence of dark matter and the strong CP problem in QCD. Axions can interact with a strong magnetic field through the Primakoff effect, wherein the axion can spontaneously convert into a photon in the presence of a strong magnetic field.

Book Launch: Steve Lamoreaux, Yale, "The Historical and Physical Foundations of Quantum Mechanics: A Brief Tour with Comments on the History of the Atomic Theory"

Given that a search on Amazon.com for books on ‘quantum theory’ returns over 10,000 hits while searching for ‘quantum physics’ returns over 20,000, one might wonder if the world needs yet another book on the subject. These numbers correspond to one book a day for 30 years, ranging from advanced mathematical treatises to books without a single equation, from deep philosophical debates between authors with different understandings of the subject, to textbooks teaching the methodology and various applications.

NPA Seminar, Wouter van de Pontseele, MIT, "Quantum technologies for neutrino measurements"

Superconducting technologies have been developed and employed with great success by the quantum information science community. More and more, these technologies show promise for fundamental physics. I want to sketch some of their possible advantages in the context of the Ricochet and Project 8 neutrino experiments.

Special Seminar: Ken Bloom, University of Nebraska-Lincoln, "How to do Particle Physics in a Climate Emergency?"

The pursuit of particle physics, or any kind of discovery-driven research, requires a stable and prosperous society. Today, our society is increasingly threatened by global climate change. Human-influenced climate change has already impacted weather patterns, and global warming will only increase unless deep reductions in emissions of CO2 and other greenhouse gases are achieved.

NPA Seminar, Trevor Wright, University of Colorado, Boulder "A New Bound on the Electron's Electric Dipole Moment"

The Standard Model cannot explain the dominance of matter over anti-matter in our universe, which indicates the existence of undiscovered time-reversal (T) symmetry violation. Proposed particle physics theories predict new particles that violate T-symmetry, which generically induce an electric dipole moment in the electron (eEDM). I will present the most precise measurement of the eEDM to date using electrons confined inside molecular ions, subject to a huge intra-molecular electric field, and evolving coherently for up to three seconds.

NPA Seminar, Yikun Wang, Caltech, “Axion Detection with Optomechanical Cavities”

In this talk, I will present our recent proposal of searching for axion dark matter with an optomechanical cavity filled with a material such as superfluid helium. Axion absorption converts a pump laser photon to a photon plus a phonon. The axion absorption rate is enhanced by the high occupation number of coherent photons or phonons in the cavity, allowing our proposal to largely overcome the extremely small axion coupling. The axion mass probed is set by the relative frequency of the photon produced in the final state and the Stokes mode.
