Designing angle-independent structural colors using Monte Carlo simulations of multiple scattering

Posted by klaurent Harvard

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Victoria Hwang, Anna B. Stephenson, Solomon Barkley, Soeren Brandt, Ming Xiao | Summary: Disordered nanostructures with correlations on the scale of visible wavelengths can show angle-independent structural colors. These materials could replace dyes in some applications because the color is tunable and resists photobleaching. However, designing nanostructures […]

Amplify-and-Forward Relaying for Hierarchical Over-the-Air Computation

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Jie Xu, Vincent K. N. Lau, Shuguang Cui, | Summary: This paper studies a hierarchical over-the-air computation (AirComp) network over a large area, in which multiple relays are exploited to facilitate data aggregation from massive WDs. We present a two-phase amplify-and-forward (AF) relaying protocol. In […]

Covariance of the redshift-space matter power spectrum after reconstruction

Posted by klaurent Tokyo

Kavli Affiliate: Chiaki Hikage | Summary:We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level order and find that the amplitude of the off-diagonal components from the trispectrum decreases by reconstruction. Using a large set of N-body simulations, we also find […]

Merging stellar and intermediate-mass black holes in dense clusters: implications for LIGO, LISA and the next generation of gravitational wave detectors

Posted by klaurent Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Manuel Arca-Sedda, Pau Amaro-Seoane, Xian Chen, , | Summary: We study the formation of intermediate-mass ratio inspirals (IMRIs) triggered by the interactions between two stellar black holes (BHs) and an intermediate-mass BH (IMBH) inhabiting the centre of a dense star cluster. We exploit $N$-body models varying the […]

An Ising Hamiltonian Solver using Stochastic Phase-Transition Nano- Oscillators

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | First 5 Authors: Sourav Dutta, Abhishek Khanna, Adou S. Assoa, Hanjong Paik, Darrell Schlom | Summary: Computationally hard problems, including combinatorial optimization, can be mapped into the problem of finding the ground-state of an Ising Hamiltonian. Building physical systems with collective computational ability and distributed parallel processing capability can accelerate […]

Doped Mott Insulators in the Triangular Lattice Hubbard Model

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Zheng Zhu, D. N. Sheng, Ashvin Vishwanath, , | Summary: We investigate the evolution of the Mott insulators in the triangular lattice Hubbard Model, as a function of hole doping $delta$ in both the strong and intermediate coupling limits. Using the advanced density matrix renormalization group (DMRG) […]

Microtextures in the Chelyabinsk impact breccia reveal the history of Phosphorus-Olivine-Assemblages in chondrites

Posted by klaurent Caltech

Kavli Affiliate: Paul D. Asimow | Summary:The geochemistry and textural associations of chondritic phosphate minerals can provide insights into the geological histories of parental asteroids, but the processes governing their formation and deformation remain poorly constrained. Here, we present a quantitative assessment of phosphorus-bearing mineral textures in the three variously-shocked lithologies (light, dark, and melt) […]

Light Dark Matter Search with a High-Resolution Athermal Phonon Detector Operated Above Ground

Posted by klaurent Stanford

Kavli Affiliate: Paul Brink | Summary:We present limits on spin-independent dark matter-nucleon interactions using a $10.6$ $mathrmg$ Si athermal phonon detector with a baseline energy resolution of $σ_E=3.86 pm 0.04$ $(mathrmstat.)^+0.19_-0.00$ $(mathrmsyst.)$ $mathrmeV$. This exclusion analysis sets the most stringent dark matter-nucleon scattering cross-section limits achieved by a cryogenic detector for dark matter particle masses […]
