Long-lived magnetization in an atomic spin chain tuned to a diabolic point

Posted by klaurent Delft

Kavli Affiliate: Sander Otte | Summary:Scaling magnets down to where quantum size effects become prominent triggers quantum tunneling of magnetization (QTM), profoundly influencing magnetization dynamics. Measuring magnetization switching in an Fe atomic chain under a carefully tuned transverse magnetic field, we observe a non-monotonic variation of magnetization lifetimes around a level crossing, known as the […]

Local Description of Decoherence of Quantum Superpositions by Black Holes and Other Bodies

Posted by klaurent Chicago

Kavli Affiliate: Robert Wald | Summary:It was previously shown that if an experimenter, Alice, puts a massive or charged body in a quantum spatial superposition, then the presence of a black hole (or more generally any Killing horizon) will eventually decohere the superposition [arXiv:2205.06279, arXiv:2301.00026, arXiv:2311.11461]. This decoherence was identified as resulting from the radiation […]

Efficient Sparse Attention needs Adaptive Token Release

Posted by dbos Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Chaoran Zhang, Lixin Zou, Dan Luo, Min Tang, Xiangyang Luo | Summary: In recent years, Large Language Models (LLMs) have demonstrated remarkable capabilities across a wide array of text-centric tasks. However, their `large’ scale introduces significant computational and storage challenges, particularly in managing the key-value states of […]
