A multi-dimensional quantum estimation and model learning framework based on variational Bayesian inference

Kavli Affiliate: Tim H. Taminiau | First 5 Authors: Federico Belliardo, Federico Belliardo, , , | Summary: The advancement and scaling of quantum technology has made the learning and identification of quantum systems and devices in highly-multidimensional parameter spaces a pressing task for a variety of applications. In many cases, the integration of real-time feedback […]

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

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

Kavli Affiliate: John Silverman | First 5 Authors: John Silverman, 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 […]

Realizing Nonreciprocal Linear Dichroism and Emission from Simple Media

Kavli Affiliate: Richard D. Robinson | First 5 Authors: Thomas J. Ugras, Thomas J. Ugras, , , | 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 […]

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

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Dan Hooper, , , | Summary: We explore a simple and predictive dark matter scenario involving a complex scalar field, $phi$, 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 […]

Spin-Polaron Mediated Superconductivity in Doped Chern Antiferromagnets

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Xuepeng Wang, Xuepeng Wang, , , | 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 […]

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

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 […]

Optically Actuated Transitions in Multimodal, Bistable Micromechanical Oscillators

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Lior Michaeli, Lior Michaeli, , , | 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 […]
