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 […]

Mergers Matter: Gravothermal Collapse in Dwarf Halos with Self-Interacting Dark Matter

Posted by klaurent MIT

Kavli Affiliate: Lina Necib | Summary:Self-Interacting Dark Matter (SIDM) models with large cross sections at relative velocities below $sim100,rm km , s^-1$ can be tested with dwarf galaxy observations. We analyze six dark-matter-only zoom-in $sim10^10,rm M_odot$ halos with diverse assembly histories, adopting a cross section over mass of $σ/m = 70,cm^2 , g^-1$. We find […]

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 […]
