Ultrafast Spin Dynamics and Photoinduced Insulator-to-Metal Transition in -
Jin Zhang, Nicolas Tancogne-Dejean, Lede Xian +4
Laser-induced ultrafast demagnetization is a phenomenon of utmost interest and attracts significant attention because it enables potential applications in ultrafast optoelectronics…
Engineering Three Dimensional Moiré Flat Bands
Lede Xian, Ammon Fischer, Martin Claassen +3
We demonstrate that the concept of moiré flat bands can be generalized to achieve electronic band engineering in all three spatial dimensions. For many two dimensional van der Waal…
Realization of Quantum Spin Hall State in Monolayer 1T'-WTe2
Shujie Tang, Chaofan Zhang, Dillon Wong +23
A quantum spin Hall (QSH) insulator is a novel two-dimensional quantum state of matter that features quantized Hall conductance in the absence of magnetic field, resulting from top…
All-Optical Materials Design of Chiral Edge Modes in Transition-Metal Dichalcogenides
Martin Claassen, Chunjing Jia, Brian Moritz +1
Manipulating materials properties far from equilibrium recently garnered significant attention, with experimental emphasis on transient melting, enhancement, or induction of electr…
