John Q Xiao (University of Delaware)17/06/2015, 08:45Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)Invited Speaker / Conférencier invitéSpin-orbital coupling driven toques have been observed in magnetic bilayers consisting of a ferromagnet (FM) and heavy metal (HM) or topological insulator (TI). It has been demonstrated that the spin-orbit torques driven by an in-plane current can switch magnetization, manipulate magnetic domains and excite magnetization auto-oscillation. However, the microscopic mechanism for the spin-orbit...Go to contribution page

Mr Bradley Hauer (University of Alberta)17/06/2015, 09:15Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)Since its inception in the early 1900s, the theory of quantum mechanics has provided an excellent model for very small objects, such as single atoms or molecules. However, as we move to larger and larger systems, we eventually return to the classic realm, where Newtonian mechanics takes over. In order to probe this quantum-to-classical crossover, we propose an experiment by which we can...Go to contribution page

When coupled to optical cavities, these resonators become an attractive means for investigating the limits of quantum mechanics, as well as powerful tools for building hybrid quantum...Go to contribution page

Callum Doolin (University of Alberta)17/06/2015, 09:45Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)Optical microdisks are intriguing devices due to their small size, compatibility with standard planar micro/nano-fabrication techniques, and ability to support high-Q whispering gallery modes. We fabricate and explore the use of thin (130 nm) Si$_3$N$_4$ disks with diameters of 15 - 30 μm as refractive index sensors, using a dimpled-tapered fiber to couple with the optical modes under water....Go to contribution page
