5/9/2018 1:30 PM 340 West Hall - Dark Matter: A theory status report

Aaron Pierce, Leinweber Center for Theoretical Physics (LCTP)

The identity of the Dark Matter that dominates the matter density of the universe remains a mystery. Increasingly sophisticated experiments have begun to probe some of the best motivated models of dark matter. I will review the theoretical status of one such paradigm, so-called Weakly Interacting Massive Particle (WIMP) Dark Matter, with particular emphasis on the implications of direct detection experiments. We will see that while the paradigm is alive and well, it is under non-trivial pressure, particularly in specific implementations, such as supersymmetry. This warrants searches for other types of Dark Matter. Time permitting, I will very briefly discuss a few such searches.

5/16/2018 12:00 PM 340 West Hall - Multidimensional Spectroscopy of Color Centers in Diamond

Matt Day, Physics

Color centers in diamond are a broad class of optically accessible physical systems which, by virtue of being embedded crystal defects in the diamond lattice, are relatively isolated from the macroscopic environment. This makes them promising candidates for a variety of applications from precision metrology to quantum information processing. One key to realizing these applications is a detailed understanding of the electron dynamics that govern the opto-electronic properties of color centers. I will present our recent work studying silicon–vacancy centers with multidimensional coherent spectroscopy, discuss the implications of these results for proposed silicon–vacancy center applications, and mention a few exciting new directions of study in the world of color center spectroscopy.

5/23/2018 12:00 PM 340 West Hall - Eigenstate Thermalization Hypothesis in Spinor Condensates

Ceren Dag, Physics

Thermalization of isolated quantum systems is a long-standing fundamental problem where different mechanisms are proposed over time. Eigenstate thermalization hypothesis (ETH) is one of the most well-known of these mechanisms. I will start my talk by introducing the problem of quantum thermalization and ETH as a possible route to thermalization. Then I will switch gears and turn to the topic of spinor Bose-Einstein condensates. Eventually the aim of the talk is to answer the question of "Could spinor condensates be another test-bench for testing eigenstate thermalization hypothesis besides widely used quantum many-body systems?". I will show the experimental advantages of spinor condensates to observe ETH and the possible limits of this model. Finally, it seems possible to draw a relation between the thermalization and localization properties of the eigenstates via studying spinor condensates.
