Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jing Wang, , , | Summary: Since the advent of autonomous driving technology, it has experienced remarkable progress over the last decade. However, most existing research still struggles to address the challenges posed by environments where multiple vehicles have to interact seamlessly. This study aims […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Kavli Affiliate: Ran Wang | First 5 Authors: Chang Liu, Chang Liu, , , | Summary: We study the linear stochastic fractional heat equation $$ fracpartialpartial tu(t,x)=-(-Delta)^fracalpha2u(t,x)+dotW(t,x), quad t>0, quad xinmathbbR, $$ where $-(-Delta)^fracalpha2$ denotes the fractional Laplacian with power $alphain (1,2)$, and the driving noise $dotW$ is a centered Gaussian field that is white […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Drew Jamieson, Drew Jamieson, , , | Summary: We present primordial non-Gaussianity predictions from a new high-precision code for simulating axion-U(1) inflation on a discrete lattice. We measure the primordial scalar curvature power spectrum and bispectrum from our simulations, determining their dependence on both scale and axion-gauge […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Katrin Becker, Katrin Becker, , , | Summary: There exists a rare class of R-symmetry gauged $N=(1,0)$ supergravities in six dimensions with gauge group $Gtimes U(1)_R$, where $G$ is semisimple with rank greater than one, and the number of tensor multiplets $n_T=1$, which are free from all […]
