Collective Communication for Distributed LLM Systems: Planning, Runtime Adaptation, and Computation Coordination
Xuebin Song, Menghao Zhang, Yuezheng Liu +5
Distributed large language model (LLM) systems increasingly rely on collective communication primitives such as AllReduce (AR), ReduceScatter (RS), AllGather (AG), and AlltoAll (A2…
Topological Surface Charge Detection via Terahertz Time-domain Spectroscopy
Tong Shen, Yiyang Xie, Yucheng Dai +4
The topological magnetoelectric effect (TME) in three-dimensional topological insulators manifests as a quantized surface charge accumulation proportional to an applied magnetic fi…
Observation of Superfluidity and Meissner Effect of Composite Bosons in GaAs Quantum Hall System
Yuanze Li, Renfei Wang, Jiahao Chen +7
The quantum Hall effect (QHE) is theoretically understood as a superfluid condensate of composite bosons (CBs) -- bound states of electrons and magnetic flux quanta. While dissipat…
Topological Surface Charge Detection via Active Capacitive Compensation: A Pathway to the 4D Quantum Hall Effect
Yuanze Li, Renfei Wang, Yifan Zhang +6
The topological magnetoelectric effect (TME) in three-dimensional topological insulators (TIs), described by , serves as a condensed-matt…
A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
Developing a Machine-Learning Interatomic Potential for Non-Covalent Interactions in Proteins
Lejia Zeng, Xintong Zhang, Yuchan Pei +4
Machine learning interatomic potentials (MLIPs) enable efficient modeling of molecular interactions with quantum mechanical (QM) accuracy. However, constructing robust and represen…
