报告介绍 报告摘要：　　In this talk I will review experimental and theoretical progress on charge and spin-based quantum computing schemes in semiconductor quantum dots. I will focus primarily on single spin and singlet triplet qubits, and discuss initialization, manipulaiton and readout of individual qubits, as well as entanglement of neighbouring qubits. I will also discuss known decoherence and dephasing ...

报告介绍 报告摘要： 　　We study 2D electronic systems whose Fermi surfaces have type-II van Hove saddle points, defined as saddle points residing at time-reversal-noninvariant momenta in Brillouin zone. We propose that triplet pairing is generically favored in such 2D systems with weak repulsive interactions. This is argued quite generally from a renormalization group treatment of these systems. Such triple...

报告介绍 报告摘要　　The Centre for Molecular and Materials Science (CMMS) at TRIUMF provides intense beams of spin-polarized muons and radioactive ions for Canadian and international researchers to probe materials at the molecular level. Material properties are determined using a series of magnetic resonance techniques known as μSR (muon spin rotation, relaxation and resonance) and βNMR (beta-­d...

报告介绍 Abstract:　　Grafting a layer of chains on a surface to form a polymer brush has been considered as an effective approach to make it antibiofouling (i.e., less adsorption of proteins). It has been proposed or generally believed that it is the hydration of such a polymer brush with a layer of immobile water molecules that avoids the protein adsorption. If this is the only reason, one should ask a num...

报告介绍 报告摘要： Unexpected and often exciting phenomena could be observed at the oxide interface, and we show that they could be understood and controlled. Oxide interfaces are home for many exciting novel phenomena. In this talk, I will show two examples on how one can engineer oxide thin films and interfaces with atomic precision, and understand their properties with transport and in situ angle resolve...

报告介绍 报告摘要： 　　This talk will highlight our recent study of nanoparticle (NP) crossing oil/water interfaces. By anchoring stimuli-responsive polymer brushes on their surfaces, NPs can readily transfer between water and oil across oil/water interfaces in response to the environmental change in ionic strength, pH, and temperature for instance. This NP crossing interfaces is obviously associated with t...

报告介绍  Abstract：In this talk, I will introduce our progress on engineering quantum anomalous Hall effect (QAHE) in graphene systems. Graphene itself is a nonmagnetic material. Through external means (doping 3d metal atoms, or using a substrate), graphene can become magnetized and its spin-orbit coupling can be greatly enhanced. We show that the synergy between Zeeman field and Rashba spin-orbit coup...

报告介绍 Abstract：We consider memory effects for spin dynamics and spin noise of electrons in two systems with disorder in the spin-orbit coupling. The disorder has the spatial scale of the order of 10 nm. First system is a two-dimensional electron gas in magnetic field. In contrast to the conventional regular spin-orbit coupling, here the memory effects speed up spin relaxation and make it Gaussian rather ...

报告介绍 报告摘要： 　　Topological insulators (TIs) are a new kind of insulators with topologically band structures originated from strong spin-orbit coupling. They are predicted to have an insulating bulk state and gapless surface states (SSs). Three dimensional (3D) TIs such as Bi2Te3 and Bi2Se3 have been experimentally verified. The 3D TIs are also well known as excellent thermoelectric materials. The mu...

报告介绍 Abstract：　　In 5d transition metal oxides such as the iridates and osmates, novel properties arise from the interplay of electron correlations and spin-orbit interactions. We investigate the electronic structure of the pyrochlore iridates, Spinel and Perovskite osmates using density functional theory, LDA+U method, and effective low energy models. We propose that pyrochlore iridates can be a Weyl ...
