Geometric frustration in Mott insulators permits perturbative electron fluctuations controlled by local spin configurations [1]. An equilateral triangle ("trimer") of spins with S=1/2 is the simplest example, in which low-energy degrees of freedom consist of built-in magnetic and electric dipoles arising from the frustrated exchange interaction. Such trimers can be weakly coupled to make multiferroics by design [2].

The neutrino burst from core collapse supernovae represents a tremendous opportunity to observe physical processes in the heart of an exploding star. The interactions of neutrinos with the matter in and around the proto-neutron star which powers the supernova provides an in-situ probe of the explosion. Details regarding the core compactness, neutron matter equation of state, shock behavior, nucleo-synthetic products, explosion time scale, fundamental neutrino properties and more may be detectable, in principle.

The burst of neutrinos created by core collapse supernovae releases some ~10^58 particles over the course of the first few tens of seconds of the explosion. Proposed next generation neutrino experiments will receive thousands to tens of thousands of events from a galactic supernova explosion. While this seems to be an embarrassment of riches compared to the 17 events observed from Supernova 1987a, I will be discussing the difficulties experimenters will face in extracting information from the signal.

Mean field games theory is a recent research area, at the frontier between applied mathematics, social sciences, and physics. It was initiated a decade ago by Pierre-Louis Lions and Jean-Michel Lasry as a tool to model certain social phenomena involving a significant number of actors - through a game theory approach - while maintaining a reasonable level of simplicity thanks to the concept of mean-field imported from physics.

Duke Physics Colloquium

"LIGO and the Detection of Gravitational Waves"

Einstein predicted the existence of gravitational waves 100 years ago. They have been recently observed from pairs of merging Black Holes by the Laser Interferometer Gravitational-wave Observatory (LIGO). The physics of gravitational waves, the detection technique, the observations, including latest results, and implications will all be discussed.
