Title: Surface Science on the Nanoscale and Optical Analogs of 2D-NMR Abstract: To be discussed are two new directions in our research group that have emerged from a decade of work on ultrafast exciton dynamics in semiconductor nanocrystals. In both cases we connect classical ideas in physical chemistry to new opportunities in materials science: By virtue of their small size, these semiconductor nanocrystals also have pronounced surface effects.
Title: Cavity Spintronics Abstract: Cavity spintronics (also known as spin cavitronics) is a newly developing, interdisciplinary field that brings together microwave and optical communities with researchers in spintronics and magnetism. The field started around 2014 when it was found that ferromagnets in cavities hybridize with both microwaves and light by light-matter interaction [1]. Since then, the emergence of cavity spintronics has attracted broad interest from groups studying quantum electrodynamics, cavity polaritons, optomechanics, superconductivity, plasmonics, and phononics.
Title: An Idiosyncratic Journey Through Academia into Art and Creative Technology Abstract: I share my academic journey from physics into art and design, and describe the projects I created along the way. My change in direction started while I was teaching physics at the University of North Carolina in Charlotte, at which time I started creating a body of work in figurative sculpture. I moved to Toronto for an MFA at OCAD University to pursue this interest, with a thesis that explored the uncanny through puppets, animatronics, and quirky algorithms.
Title: Wet, Wiggly, Weird, and Wonderful – New Discoveries in Nanofluidics Abstract: About 25 years ago, pioneers began to borrow fabrication techniques from the semiconductor industry to make tiny fluidic circuits on chips. That field of research became known as microfluidics, because the chips featured tubes that were smaller than a millimeter.
Title: Ground State Selection in Quantum Pyrochlore Magnets Abstract: The pyrochlore lattice, a network of corner-sharing tetrahedra, is one of the most pervasive crystalline architectures in nature that supports geometrical frustration. We and others have been interested in a family of rare earth pyrochlore magnets with local XY anisotropy, that can display quantum S=1/2 magnetism on such a lattice. I will discuss up to three such magnets, Yb2Ti2O7, Er2Ti2O7 and Er2Pt2O7.

Title: Chiral Gold Nanorod and Nanocage Structures Abstract: Multistrand 7-1 helical Au24, Au32, and Au40 structures with three, four, and five gold atoms in the central strand and 21, 28, and 35 gold atoms in the coaxial tube are investigated using relativistic density functional theory.
