Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Harikrishnan KP, Varun Harbola, Jaehong Choi, Kevin J. Crust, Yu-Tsun Shao | Summary: Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materials that lack inversion symmetry. In contrast, the flexoelectric effect […]

Aiming at the complex anatomical structure of spinal images, this paper introduces a […]
Kavli Affiliate: Stephanie Wehner | First 5 Authors: Thomas R. Beauchamp, Hana Jirovská, Scarlett Gauthier, Stephanie Wehner, | Summary: We propose an architecture for scheduling network operations enabling the end-to-end generation of entanglement according to user demand. The main challenge solved by this architecture is to allow for the integration of a network schedule with […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Sam R. Katiraee-Far, Yuta Matsumoto, Brennan Undseth, Maxim De Smet, Valentina Gualtieri | Summary: Developing optimal strategies to calibrate quantum processors for high-fidelity operation is one of the outstanding challenges in quantum computing today. Here, we demonstrate multiple examples of high-fidelity operations achieved using a unified global […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Niels T. Pronk, Bowy M. La Rivière, Natalia Chepiga, , | Summary: We report a phase diagram of the antiferromagnetic spin-1 chain with nearest-neighbor Heisenberg and three-site interactions in the presence of single-ion anisotropy. We show that the Gaussian and Ising transitions that separate the topological Haldane […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Francisca Sagredo, María Camarasa-Gómez, Francesco Ricci, Aurélie Champagne, Leeor Kronik | Summary: Hybrid functionals have been considered insufficiently reliable for the prediction of band gaps in solids and surfaces. We revisit this issue with a new generation of optimally-tuned range-separated hybrid functionals, focusing on the reconstructed […]
Kavli Affiliate: Wei Gao | First 5 Authors: Qiaoling Chen, Shenggui Li, Wei Gao, Peng Sun, Yonggang Wen | Summary: In recent years, Large Language Models (LLMs) have exhibited remarkable capabilities, driving advancements in real-world applications. However, training LLMs on increasingly long input sequences imposes significant challenges due to high GPU memory and computational demands. […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Juntai Cao, Jiaqi Wei, Chenyu You, Dujian Ding | Summary: Despite the remarkable successes of Large Language Models (LLMs), their fundamental Transformer architecture possesses inherent theoretical limitations that restrict their capability to handle reasoning tasks with increasing computational complexity. Chain-of-Thought (CoT) prompting has emerged as […]
