A quantized anomalous Hall effect above 4.2 K in stacked topological insulator/magnet bilayers

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Rakshit Jain, Matthew Roddy, Vishakha Gupta, Benjamin Huang, Hasan M. Sayeed | Summary: Quantized anomalous Hall effects (QAHEs) occur in remarkable electronic states which possess not only quantized Hall signals but in some cases regions of dissipationless electron transport. The initial demonstrations of a QAHE in […]

Baseband control of single-electron silicon spin qubits in two dimensions

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Florian K. Unseld, Brennan Undseth, Eline Raymenants, Yuta Matsumoto, Saurabh Karwal | Summary: Micromagnet-enabled electric-dipole spin resonance (EDSR) is an established method of high-fidelity single-spin control in silicon. However, the resulting architectural limitations have restrained silicon quantum processors to one-dimensional arrays, and heating effects from the associated […]

Towards Flexible 3D Perception: Object-Centric Occupancy Completion Augments 3D Object Detection

Kavli Affiliate: Feng Wang | First 5 Authors: Chaoda Zheng, Feng Wang, Naiyan Wang, Shuguang Cui, Zhen Li | Summary: While 3D object bounding box (bbox) representation has been widely used in autonomous driving perception, it lacks the ability to capture the precise details of an object’s intrinsic geometry. Recently, occupancy has emerged as a […]
