“Quanta of the Third Kind: Anyons”

For many years physicists divided the world of quantum particles into two kingdoms – bosons and fermions. Anyons are particles with a sort of memory, that fall outside those kingdoms. In recent decades theorists have produced an enormous literature about the possible occurrence and properties of anyons. It is only in the last few months, however, that clear experimental confirmation has appeared. I will review the theoretical background and describe the breakthrough experiments. Anyons will be central in a new and promising method of information processing: topological quantum computing.

“Unmasking Black Holes with the Event Horizon Telescope”

Black holes are, without question, one of the most bizarre and mysterious phenomena predicted by Einstein’s theory of general relativity. They correspond to infinitely dense, compact regions in space and time, where gravity is so extreme that nothing, not even light, can escape from within. And, their existence raises some of the most challenging questions about the nature of space and time. Over the past few decades, astronomers have identified numerous tantalizing observations that suggested that black holes are real. This past April, the search for confirmation changed dramatically with the publication of the first image ever taken of a black hole, rendering tangible what was previously only the purview of theory and science fiction. I will describe how these observations were made, how the images were generated, how quantitative measurements were obtained, and what they all mean for gravity and black hole astronomy.

“Cancer and Light: How optical sciences and engineering impact cancer research and patient care”

The multiple interactions of light with biomolecules, cells and tissues enable established and emerging techniques and technologies used in cancer research and patient care. These approaches range from simple, point-of-care devices to complex, multifunctional platforms combined with complementary non-optical methods, including nanotechnologies, robotics, bioinformatics and machine learning. This seminar will use specific examples from current research to illustrate the biophysical and biological principles underlying the emerging fields of “onco-photonics” or “photo-oncology”.

“Leveraging Local Symmetry Breaking to Engineering Novel Materials”

The 20^th century has been dominated by the realization that symmetry and symmetry breaking influence the forces that govern our universe and are keys to much of the novel phenomena observed in materials today. Recently it has been realized that, even if the global symmetry of a system is retained, a local symmetry breaking can still drive a variety of novel fascinating behaviors. In this talk I will present the effect that local breaking of inversion, translational and rotational symmetry can have in defining fundamental properties of matter from topological phases to superconductivity and how it can be used as a tuning parameter to control novel properties in van der Waals heterostructures.

“The Right to Know and Love the Night Sky”

In this talk, I will argue that treating the marginalization of certain groups in science as a workforce problem ignores the deeper issue: that wondering about the universe is a fundamental right. I will discuss what it means to create the conditions in which we all have a chance to know and love the night sky and all of the particles that populate it.
