Precision beta decay experiments require high order QED corrections including the (very large) effects of the nuclear Coulomb field. In this talk I will present new work that explains how to construct a low-energy effective field theory for long-distance QED effects in beta decay. I will explain how:
Our knowledge of the fundamental interactions governing the universe relies on our ability to accurately investigate the behavior of elementary particles. Whether they are electrons, photons or else, all particles walk their path in both time and space simultaneously, leaving behind a unique signature. In this seminar, I will review the most advanced methods to detect these spatio-temporal signatures using an old ally: the silicon crystal.

Over 50 years ago, it was predicted that it is possible to split an atom with a neutrino interaction, but there has never been a concerted experimental effort to confirm this phenomenon. The existence of this process would inform nuclear astrophysics, nuclear reactor monitoring and give a vantage into a process that bridges both the weak and strong fundamental interactions. This would add the neutrino to the selective group of particles confirmed to induce nuclear fission.
The quantum Zeno effect refers to the freezing of the time evolution of a quantum system subjected to repeated
measurements. In this talk we try to answer the question, as to whether the Zeno effect can stop stochastic decay events like a photon jump from a cavity. There is a time scale governing the rate at which the

Join the Kimball Smith Series for a moderated panel followed by small group discussions regarding quantum technologies and their relevance to international affairs.
The panel will feature Mark Ritter (Chair of Physical Science Council at IBM Research) and Robert Schoelkopf (Sterling Professor of Applied Physics and Professor of Physics; Director of Yale Quantum Institute). Both panelists are members of the U.S. National Quantum Initiative Advisory Committee.
We magnetically levitate microdiamonds in vacuum, and the microdiamonds we have made contain single nitrogen-vacancy centres with the longest spin coherence times. We aim to use this setup to put a microdiamond into a macroscopic quantum superposition of being in two places at once. But what is the gravitational effect of a mass in such a superposition? Sougato Bose has proposed a way to probe this question experimentally: if gravity is quantum then it could entangle two microdiamonds that are each in spatial superpositions.
Speaker: Professor Holden Thorp, Editor-in-Chief of the Science Family of Journals and a Professor of Chemistry and Medicine at George Washington University.
