Irregular Metamaterial Networks

Posted by klaurent Caltech

Kavli Affiliate: Chiara Daraio | Summary:Metamaterials can achieve exceptional functionality through careful engineering of their mesoscale structure. Although appropriately introduced irregularities can be advantageous, current approaches largely conform to regular structures to preserve tractability. Here, we contend that network theory, enriched with geometry and physics, provides a natural framework for designing metamaterials with controlled irregularities […]

Dexterity-BEV: Aligning 3D World and Actions for Generalizable Robot Policies Learning

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:End-to-end manipulation policies, combined with web-scale pretrained Vision-Language Models (VLMs), show the promise for generalizable and dexterous robotic manipulation. However, they inherit two key limitations from 2D foundation models: 1) the reliance on 2D RGB inputs that ignores the intrinsically 3D nature of manipulation; and 2) the lack of spatial 3D […]

Towards Heisenberg Scaling: Measurement-Efficient Non-Orthogonal Quantum Eigensolver

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | Summary:The Non-Orthogonal Quantum Eigensolver (NOQE) provides an accurate framework for electronic-structure calculations, but the estimation of its Hamiltonian and overlap matrix elements relies on sampling and requires $O(1/varepsilon^2)$ circuit repetitions to achieve additive precision $varepsilon$. Here, we reformulate this matrix-element estimation step as a collection of amplitude-estimation tasks and integrate […]

Diagnosing LLM Arbitration Behavior over Pre-evidence Epistemic States in RAG-based Fact-Checking

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:In RAG-based fact-checking, LLMs are increasingly used as verifiers to check given claims against retrieved evidence. Their parametric knowledge can induce pre-evidence tendencies that may conflict with the retrieved context, yet existing evaluation frameworks do not characterize such prior-context discrepancy or measure how verifiers arbitrate between parametric and contextual signals. We […]

What controls the superconducting dome of electron-doped FeSe?

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | Summary:Superconducting domes are conspicuous features of the phase diagrams of most unconventional and high-temperature superconductors. The superconducting transition temperature ($T_c$) of FeSe can be dramatically enhanced with electron doping, but unlike all other high-temperature and unconventional superconductors, its full phase diagram and superconducting dome have yet to be fully explored. […]

Defect-engineered scaling of lead-free ferroelectrics with ultralow-voltage switching

Posted by klaurent Cornell

Kavli Affiliate: David Muller | Summary:Scaling ferroelectrics to nanometer thicknesses remains a central challenge for low-power, nonvolatile electronics, as leakage currents increasingly dominate with reduced dimensions. Alkali-based, lead-free ferroelectrics offer an environmentally sustainable alternative to lead-based systems, yet their scaling is severely limited by leakage arising from volatile alkali constituents. Here, we show that this […]

Magneto-Optical Detection of Anisotropic Spin Currents in Altermagnetic RuO2

Posted by klaurent Cornell

Kavli Affiliate: Farhan Rana | Summary:Altermagnets are a recently identified class of collinear antiferromagnets that host large spin-split electronic bands, offering a promising platform for efficient spin-current generation. Among proposed candidates, the metallic oxide RuO2 is predicted to exhibit strong altermagnetic spin splitting; however, whether it sustains robust magnetic order beyond the ultrathin thickness limit […]

Examining the Challenges of Intellectual Property in AI-Generated Productions

Posted by klaurent Delft

Kavli Affiliate: Mazhar Ali | Summary: With the advancement of artificial intelligence systems capable of autonomously generating artistic, literary, musical works, and even inventions without direct human intervention, the intellectual property (IP) regime faces unprecedented questions and challenges. The most critical issue concerns the ownership of moral and economic rights in the absence of a […]
