PPPL intern Joseph Labrum helped build components for a “zero knowledge” system that may have applicability to future nuclear arms control agreements

Joseph Labrum spent his summer internship building components to upgrade an experiment that successfully compared physical objects without learning anything about the objects themselves. Such a “zero-knowledge protocol” system is a promising first step toward a technique that could possibly be used in future disarmament agreements, pending the results of further development, testing, and evaluation. While important questions remain, it might have potential application to verify that nuclear warheads are in fact true warheads without revealing classified information.

COLLOQUIUM: Better Cities Through Imaging

With millions of interacting people and hundreds of governing agencies, urban environments are the largest, most dynamic, and most complex macroscopic systems on Earth. The interaction between the three fundamental components of that system (human, natural, and built) can be studied much like any physical system, with observation and application of physical principles to the collection and analysis of that data.

COLLOQUIUM: Pilot-wave hydrodynamics

A decade ago, Yves Couder and coworkers discovered that droplets walking on a vibrating fluid bath exhibit several features previously thought to be exclusive to the microscopic, quantum realm. These walking droplets propel themselves by virtue of a resonant interaction with their own wavefield, and so represent the first macroscopic realization of a pilot-wave system of the form proposed for microscopic quantum dynamics by Louis de Broglie in the 1920s.
