The magic of atomically thin materials The realization of two dimensional (2D) atomically thin layers has made it possible to tune the properties of a material without changing its chemical composition, for example by introducing strain, plucking out atoms, or intentionally stacking the layers in various ways. In particular, by tuning the twist Read More

It has long been believed that three possibilities exist for the gap: Read More

The interfacial Dzyaloshinskii-Moriya interaction in thin magnetic films: a smorgasbord of effects and applications  Dr Karen Livesey, The University of Newcastle Abstract: The Dzyaloshinskii-Moriya interaction (DMI) is an antisymmetric magnetic exchange interaction arising from spin-orbit coupling, discovered in the 1950s in order to understand bulk materials. In the Read More

The fate of quantum impurities in a Fermi sea The scenario of a mobile impurity immersed in a Fermi gas appears in a wide variety of systems ranging from neutron stars to cold atomic gases to the absorption spectra in doped semiconductors. In this case, the impurity attractively interacts with the surrounding fermions and becomes “dressed” by Read More

Speaker: Anton Burkov (University of Waterloo) Topological Metals One of the major themes of the modern condensed matter physics is the study of materials with nontrivial electronic structure topology. Particularly significant progress in this field has happened within the last decade, due to the discovery of topologically nontrivial states of matter, that have a gap Read More
