Colloquia typically take place on Mondays in the Dorothy Vernon Room, adjacent to the dining hall of the New Dorm.
Dinner 5:30-6:30 p.m., followed by the colloquium 6:30-7:30 p.m. Meal tickets will be provided for those not on the meal plan.

Looking at the universe, both big & small, and hot & cold: life on the frontiers of physics
Understanding something often requires getting a fresh perspective on it. The same is true in physics – in order to understand our universe, we must move beyond what we can see with our eyes. In this talk we will describe two very different tools for observing and investigating new physics. Gamma ray telescopes allow us to probe one of the hottest unsolved problems in astrophysics, the origins and acceleration mechanisms of cosmic rays – charged particles from space. The Scanning Tunneling Microscope (STM) allows us to measure the behavior of electrons around individual atoms, and has been used to investigate the biggest questions in condensed matter physics, such as the onset of superconductivity in materials at very low temperatures. In addition to discussing these techniques and the very different corners of physics they reveal, we will also share our experiences and thoughts on the life of physicists from grad school through tenure and beyond.

What do white dwarf stars, thermonuclear fusion, and ultracold plasmas have in common?
Plasmas comprise the vast majority of the known universe and exist over a wide range of temperatures and densities. Most plasmas form from energetic collisions between particles in a hot gas which result in the liberation of one or more electrons. However, using tools from experimental atomic physics, researchers are able to create "ultracold plasmas," which exist at temperatures close to absolute zero. Due to their large electrical potential energies and comparatively small kinetic energies, ultracold plasmas fall into a regime of plasma systems which are called “strongly coupled,” giving them properties similar to certain astrophysical systems and fusion-class plasmas. In this talk I will give an overview of the field of ultracold plasmas, provide details about some of our recent work, and show how some of this work relates to high energy-density plasmas.
