Micro-reflectance and transmittance spectroscopy: a versatile and powerful tool to characterize 2D materials
Riccardo Frisenda, Yue Niu, Patricia Gant +9
Optical spectroscopy techniques such as differential reflectance and transmittance have proven to be very powerful techniques to study 2D materials. However, a thorough description…
ARCANA: A Reflective Multi-Agent Program Synthesis Framework for ARC-AGI-2 Reasoning
Kunbo Zhang, Lei Fu, Zeyu Wang +2
We present ARCANA, a collaborative multi agent framework for solving ARC AGI 2 tasks under strict test time and hardware constraints. ARCANA decomposes each task into iterative per…
The exotic inverted Kloosterman sum
Lei Fu, Daqing Wan
Let be a product of finitely many finite fields containing , a nontrivial additive character, and $Ï: B^*\to \over…
Consistency between Bulk and Boundary Causalities in Asymptotically Anti-de Sitter Spacetimes
Lei Fu, Keisuke Izumi, Daisuke Yoshida
We investigate the consistency between bulk and boundary causalities in static, spherically symmetric, asymptotically anti-de Sitter (AdS) spacetimes. We derive a general formula t…
Electrically tunable moiré magnetism in twisted double bilayers of chromium triiodide
Guanghui Cheng, Mohammad Mushfiqur Rahman, Andres Llacsahuanga Allcca +10
Moiré superlattices in van der Waals structures can be used to control the electronic properties of the material and lead to emergent correlated and topological phenomena. Its fir…
Physics Symbolic Learner for Discovering Ground-Motion Models Via NGA-West2 Database
Su Chen, Xianwei Liu, Lei Fu +3
Ground-motion model (GMM) is the basis of many earthquake engineering studies. In this study, a novel physics-informed symbolic learner (PISL) method based on the Nest Generation A…
