Dynamics of Spinning Binaries From an Effective Field Theory Perspective
Speaker: Radu Roiban (Penn State University)Host: Ergin Sezgin
The general relativistic two-body dynamics is a subject of great theoretical and practical interest in light of the ongoing observations of gravitational waves by the LIGO/Virgo observatories. In recent years the classical limit of quantum scattering amplitudes provided a means to establish the state of the art in the weak-field [...]
AMO/IQSE seminar: Time and Quantum Gravity
Speaker: William G. Unruh (Canadian Institute for Advanced Research; University of British Columbia; Institute for Quantum Science and Engineering, Texas A&M University; Hagler Institute for Advanced Study )
The very different roles that time plays in Quantum Mechanics and in Gravity seems to be one of the main impediments to developing a quantum theory of gravity. I will review these and the problems they cause each other. Unfortunately I will not give a solution.
A New Step in Interacting Dark Sector Cosmologies for the Hubble Tension and Large Scale Structure
Speaker: Taewook Youn (University of Texas, Austin)Host: Doojin Kim
In this talk, I propose Stepped Partially Acoustic Dark Matter (SPartAcous), a new class of interacting dark sector models with a qualitatively new cosmological behavior that can simultaneously address the two most important tensions in cosmological data, the H0 and S8 tensions. The defining element of this class of models [...]
Time-reversing a laser: What it means and what it’s good for
Speaker: A. Douglas Stone (Yale University)Host: Alexey Belyanin
Over a decade ago an overlooked symmetry of Maxwell’s equations coupled to matter was discovered. The linear Maxwell wave equation in the presence of a gain medium can describe a laser at threshold. This is the point at which gain balances loss and the system self-organizes to oscillate coherently at [...]
Physics Demonstrations at Boonville Days
Enjoy fun family-friendly physics demonstrations with the Just Add Science students and Dr. Tatiana!

A Case Study in Nuclear Proliferation – The Iran Nuclear Deal and the Responsibility of Physicists
Speaker: Matthias Grosse Perdekamp (University of Illinois Urbana Champaign)Host: Rainer Fries
The first nuclear weapon was tested in Alamogordo, NM, in July 1945. In the following month, Hiroshima and Nagasaki were destroyed through the explosion of two nuclear warheads. These horrifying strikes directly led to the surrender of Japan almost 4 years after its attack on Pearl Harbor. An industrial scale [...]

Boosting Light Dark Matter with Cosmic Rays and Supernovae
Speaker: Christopher Cappiello (Queen's University)Host: Doojin Kim
Direct detection experiments set strong constraints on scattering between dark matter (DM) and nuclei, but rapidly lose sensitivity when the DM mass falls below ~10 GeV. Such light DM traveling at typical halo velocities doesn't carry enough momentum to trigger traditional detectors, so new techniques or low-threshold detectors are needed [...]
