Kavli Affiliate: Giordano Scappucci | First 5 Authors: Karina Hudson, Karina Hudson, , , | Summary: Constricting transport through a one-dimensional quantum point contact in the quantum Hall regime enables gate-tunable selection of the edge modes propagating between voltage probe electrodes. Here we investigate the quantum Hall effect in a quantum point contact fabricated on […]
Kavli Affiliate: Feng Wang | First 5 Authors: Zhehao Ge, Zhehao Ge, , , | Summary: Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem in condensed matter physics. Progress in this topic has been limited by a lack of single-defect-resolved experimental […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Yi J. Zhao, Yi J. Zhao, , , | Summary: Synchronization in quantum systems has been recently studied through persistent oscillations of local observables, which stem from undamped modes of the dissipative dynamics. However, the existence of such modes requires fine-tuning the system to satisfy specific […]
Kavli Affiliate: Wei Gao | First 5 Authors: Han Lu, Han Lu, , , | Summary: Synchronous Reinforcement Learning (RL) post-training has emerged as a crucial step for enhancing Large Language Models (LLMs) with diverse capabilities. However, many systems designed to accelerate RL post-training still suffer from low resource utilization and limited scalability. We present […]
Kavli Affiliate: Grace Xing | First 5 Authors: Alice Ho, Alice Ho, , , | Summary: The importance of electrical contact resistance and thermal boundary resistance has increased dramatically as devices are scaled to atomic limits. The use of a rich range of materials with various bandstructures (e.g. parabolic, conical), and in geometries exploiting various […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiaqi Wei, Jiaqi Wei, , , | Summary: Deliberative tree search is a cornerstone of modern Large Language Model (LLM) research, driving the pivot from brute-force scaling toward algorithmic efficiency. This single paradigm unifies two critical frontiers: textbfTest-Time Scaling (TTS), which deploys on-demand computation to solve hard […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Chenghao Wang, Chenghao Wang, , , | Summary: Multi-modal ground-aerial robots have been extensively studied, with a significant challenge lying in the integration of conflicting requirements across different modes of operation. The Husky robot family, developed at Northeastern University, and specifically the Husky v.2 discussed in this […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Elias Kristmann, Elias Kristmann, , , | Summary: Although variable-rate compressed image formats such as JPEG are widely used to efficiently encode images, they have not found their way into real-time rendering due to special requirements such as random access to individual texels. In this paper, we […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, Juan Daniel Torres Luna, , , | Summary: To observe Majorana bound states, and especially to use them as a qubit, requires careful optimization of competing quality metrics. We systematically compare Majorana quality in proximitized semiconductor nanowires and quantum dot chains. Using multi-objective […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Fengze Xie, Fengze Xie, , , | Summary: Fixed-wing unmanned aerial vehicles (UAVs) offer endurance and efficiency but lack low-speed agility due to highly coupled dynamics. We present an end-to-end sensing-to-control pipeline that combines bio-inspired hardware, physics-informed dynamics learning, and convex control allocation. Measuring airflow on a […]
