Abstract:

Van der Waals heterostructures, built from two-dimensional materials, feature atomically flat interfaces and exhibit rich interlayer coupling, leading to the emergence of diverse novel quantum states. The precise construction and programmable control of these interfacial quantum states are essential for realizing their potential in functional device applications. In this talk, I will present our recent progress in the engineering and programmable tuning of 2D interfacial quantum states and phenomena—including ferroelectric topological edge states, interfacial magnetic spin Hall effects, nonreciprocal Ising superconductivity, and isotropic interfacial ferromagnetism in graphene moiré heterostructures, topological semimetal/Fe3GeTe2 heterostructures and twisted Ising superconductors. By achieving nonvolatile control over these quantum states, we have designed innovative devices such as noise-immune neuromorphic computing systems, quantum neuron transistors, and superconducting Josephson junctions capable of continuously storing quantum phase information.

 

Biography:

Professor Bin Cheng received both his B.Sc. and M.Sc. degrees from the Department of Physics, Nanjing University, and obtained his Ph.D. in 2015 from the University of California, Riverside, USA.
