Abstract:   The origin of cosmic acceleration remains an open question: is it caused by a dark energy and if so, what are its properties? Or is our theory of gravity incomplete on the largest scales? These questions have driven...

Abstract:   I will talk about GammaTPC, a new MeV-GeV gamma-ray instrument based on liquid argon time projection chamber (TPC) technology.  The MeV sky in particular is poorly measured, largely due to instrumental challenges. A transformative instrument in this energy...

Abstract:   The promise of quantum is real, and we are beginning to see where this technology can have the greatest impact. Decades of quantum research and development point to one primary class of practical application for quantum computing next...

Abstract: The first fractions of a second after the Big Bang likely involved physics operating at energy scales orders of magnitude above those accessible to terrestrial experiments. This epoch — known as inflation — played a crucial role in cosmic...

Abstract: A high-luminosity high-energy polarized electron-hadron collider will be built at Brookhaven National Laboratory (BNL) in partnership with Thomas Jefferson National Accelerator Facility (TJNAF) and will start operation in the middle of the next decade. The EIC will be capable...

No Colloquium on 03/23 - Stanford Spring Break. We will resume the regular series soon.

Abstract:   Neutrinos are elusive particles with unique properties that offer key insights into the fundamental structure of matter and the cosmic sources that produce them. The Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation, 20-kiloton liquid scintillator detector, the...

No Colloquium on 03/09.   We will resume the regular series soon.

Abstract:   Quantum electrodynamics (QED) is a well-established physical theory and its predictions have been confirmed experimentally in various regimes and with extremely high accuracy. However, there are still areas of QED that deserve theoretical and experimental investigation, especially when...
