Electron ptychography reveals a ferroelectricity dominated by anion displacements

Posted by dbos Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Harikrishnan KP, Ruijuan Xu, Kinnary Patel, Kevin J. Crust, Aarushi Khandelwal | Summary: Sodium niobate, a lead-free ferroic material, hosts delicately-balanced, competing order parameters, including ferroelectric states that can be stabilized by epitaxial strain. Here, we show that the resulting macroscopic ferroelectricity exhibits an unconventional microscopic […]

Controlling assembly and oscillations of elastic membranes with an active fluid

Posted by dbos UCSB

Kavli Affiliate: Mark Bowick | First 5 Authors: John Berezney, Sattvic Ray, Itamar Kolvin, Mark Bowick, Seth Fraden | Summary: We use the chaotic flows generated by a microtubule-based active fluid to assemble self-binding actin filaments into a thin elastic sheets. Starting from a uniformly dispersed state, active flows drive the motion of actin filaments, […]

Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas, Lia Marta Bernabo, Varghese Reji | Summary: Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasingly large number of them […]

Long Range Energy-energy Correlator at the LHC

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Yuxun Guo, Xiaohui Liu, Feng Yuan, , | Summary: We study the forward-backward azimuthal angular correlations of hadrons in association with multi-particle production in the central rapidity region in proton-proton collisions at the LHC. We apply the nucleon energy-energy correlator framework, where the spinning gluon distribution introduces […]

Simulation of atom trajectories in the original Stern-Gerlach experiment

Posted by dbos Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Faraz Mostafaeipour, S. Suleyman Kahraman, Kelvin Titimbo, Yixuan Tan, Lihong V. Wang | Summary: Following a comprehensive analysis of the historical literature, we model the geometry of the Stern$unicode{x2013}$Gerlach experiment to numerically calculate the magnetic field using the finite-element method. Using this calculated field and Monte […]

Cross-sectional imaging of speed-of-sound distribution using photoacoustic reversal beacons

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yang Wang, Danni Wang, Liting Zhong, Yi Zhou, Qing Wang | Summary: Photoacoustic tomography (PAT) enables non-invasive cross-sectional imaging of biological tissues, but it fails to map the spatial variation of speed-of-sound (SOS) within tissues. While SOS is intimately linked to density and elastic modulus of tissues, […]

$boldsymbol{Steiner}$-Hardness: A Query Hardness Measure for Graph-Based ANN Indexes

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Zeyu Wang, Qitong Wang, Xiaoxing Cheng, Peng Wang, Themis Palpanas | Summary: Graph-based indexes have been widely employed to accelerate approximate similarity search of high-dimensional vectors. However, the performance of graph indexes to answer different queries varies vastly, leading to an unstable quality of service for downstream […]
