Sc. in Mathematics/Physics, The University of Hong Kong, Hong Kong, 2005

研究领域

Yang’s research interests are focused on the field of theoretical condensed matter physics, with particular emphasis on the topological aspects in condensed matter systems. The aim is not only to deepen our understanding of the fundamental physics, but also to enable the application of such understanding for the technological development. Current research interests include: Topological materials such as topological insulators, topological superconductors, topological semimetals etc. Topological materials have revolutionized our understanding of the fundamentals of solids. They are characterized by a special topological ordering and on their surfaces there are topological boundary states which can carry currents with low dissipation. These materials have promising applications in quantum electronics. Physical properties of novel 2D materials like graphene, silicene, transition metal dichalcogenides, 2D electrides etc. The 2D nature makes these materials behave quite differently from usual 3D materials. They hold great potential for constructing novel electronic devices. Spin pumping and spin transfer torque. The interplay between magnetic ordering and carrier transport is an intriguing research topic. Important effects like the GMR have enabled a tremendous increase of the information storage density. The objective here is to understand the fundamental physics and to design nano magnetic devices with new functions and better performance. Various theoretical methods were used in research such as first-principles DFT calculations, semi-classical approach, tight-binding modeling, Green’s function method, non-equilibrium Schwinger-Keldysh technique, scattering approach, and various kinds of numerical techniques.
