Phase Dynamics in RF Driven Graphene Josephson Junctions

When
-

Josephson junctions driven by RF excitation can exhibit phase locking - the inverse AC Josephson effect.  This synchronization gives rise to quantized DC voltage plateaus called Shapiro steps that are the basis of modern voltage standards.  While the nonlinear dynamics of conventional Josephson junctions were an intense area of research in the 1980s, this measurement technique has reemerged in the past decade in materials science as a probe for topological states of matter.  In this talk, I will present measurements of graphene Josephson junctions which show unique patt

Quantum measurement dynamics of a driven ensemble of atoms in a QED cavity

When
-
Measurements have played a fundamental role in quantum mechanics since its very beginning. Consequently, they have been a topic of research across various fields, giving rise to e.g., the theory of continuous measurements in quantum optics, or the study of entanglement phase transitions in condensed matter systems.

First Results from the Muon g-2 Experiment at Fermilab’s Muon Campus

When
-

Abstract: The much anticipated initial results from the Muon g-2 experiment at Fermilab’s Muon Campus were released earlier in the year. The new determination of the muon’s anomalous magnetic moment is in good agreement with the intriguing value obtained at Brookhaven National Laboratory 20 years ago. The Muon Campus at Fermilab is a new accelerator facility capable of delivering the intense beams of muons required for the Muon g-2 and Mu2e experiments. This talk will discuss the Muon Campus physics program with an emphasis on the recent Muon g-2 results.
