Harnessing Bayesian Statistics to Accelerate Iterative Quantum Amplitude Estimation

Posted by klaurent July 30, 2025Peking

Kavli Affiliate: Li Xin Li| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We establish a unified statistical framework that underscores the crucial role statistical inference plays in Quantum Amplitude Estimation (QAE), a task essential to fields ranging from chemistry to finance and machine learning. We use this framework to harness Bayesian statistics for improved […]

Sleep pressure is differentially regulated by molecularly distinct subtypes of Lhx6-positive and Lhx6-negative neurons of the zona incerta.

Posted by dbos July 30, 2025August 11, 2025Hopkins

Kavli Affiliate: Seth Blackshaw | Authors: Parris Washington Chandler, Sang Soo Lee, Leighton Duncan, Dong Won Thomas Kim, Mark Wu and Seth Blackshaw | Summary: Sleep pressure, the accumulating drive towards sleep during wakefulness, is shaped by Lhx6-positive GABAergic neurons in the zona incerta (ZI). Here, we show that these neurons are broadly activated both […]

SHELLQs-JWST perspective on the intrinsic mass relation between supermassive black holes and their host galaxies at z > 6

Posted by klaurent July 30, 2025Tokyo

Kavli Affiliate: John Silverman | Summary:The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The James Webb Space Telescope (JWST) has opened such investigations by detecting the host galaxies of AGN and more luminous quasars within the first […]

Realizing Nonreciprocal Linear Dichroism and Emission from Simple Media

Posted by klaurent July 30, 2025Cornell

Kavli Affiliate: Richard D. Robinson | Summary:Reciprocity, the principle that a system response is identical in the forward path compared to the backward path, is a fundamental concept across physics, from electrical circuits and optics to acoustics and heat conduction. Nonreciprocity arises when this symmetry is broken, enabling directional-dependent behavior. In photonics, nonreciprocity allows control […]

Gamma-Rays and Gravitational Waves from Inelastic Higgs Portal Dark Matter

Posted by klaurent July 30, 2025Chicago

Kavli Affiliate: Gordan Krnjaic | Summary:We explore a simple and predictive dark matter scenario involving a complex scalar field, $φ$, coupled to the Higgs portal with no additional field content. In the UV, the field possesses a global $U(1)$ symmetry which is broken by mass terms and Higgs portal interactions. In the mass basis, the […]

Spin-Polaron Mediated Superconductivity in Doped Chern Antiferromagnets

Posted by klaurent July 30, 2025Cornell

Kavli Affiliate: Debanjan Chowdhury | Summary:The study of interacting topological bands with a tunable bandwidth offers a unique platform to study the interplay of intertwined orders and emergent non-electronic excitations. Here we design a time-reversal symmetric and sign-problem-free electronic model with tunable Chern bands carrying valley-contrasting Chern number, interacting via competing (anti-)ferromagnetic interactions. Using numerically […]

On the origins of oxygen: ALMA and JWST characterise the multi-phase, metal-enriched, star-bursting medium within a ‘normal’ $z > 11$ galaxy

Posted by klaurent July 30, 2025Cambridge

Kavli Affiliate: Roberto Maiolino| First 5 Authors: Joris Witstok, Joris Witstok, , , | Summary:The unexpectedly high abundance of galaxies at $z > 11$ revealed by JWST has sparked a debate on the nature of early galaxies and the physical mechanisms regulating their formation. The Atacama Large Millimeter/submillimeter Array (ALMA) has begun to provide vital […]

Identification and photometric classification of extragalactic transients in the Vera C. Rubin Observatory’s Data Preview 1

Posted by klaurent July 30, 2025Stanford

Kavli Affiliate: Steven Kahn | Summary:The Vera C. Rubin Observatory will soon survey the southern sky, delivering a depth and sky coverage that is unprecedented in time domain astronomy. As part of commissioning, Data Preview 1 (DP1) has been released. It comprises a LSSTComCam observing campaign between November and December 2024 with multi-band imaging of […]

Optically Actuated Transitions in Multimodal, Bistable Micromechanical Oscillators

Posted by klaurent July 30, 2025Caltech

Kavli Affiliate: Harry Atwater | Summary:We experimentally demonstrate a new class of optomechanical nonlinearities in weakly damped micromechanical resonators, arising from the interplay between the Duffing nonlinearity, intermodal coupling, and thermal fluctuations. Within the bistable regime of a single Duffing mode driven by radiation pressure forces, we observe stochastically generated sidebands, originating from thermal fluctuations […]
