An On-demand Photonic Ising Machine with Simplified Hamiltonian Calculation by Phase encoding and Intensity Detection

Posted by dbos July 11, 2022Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiayi Ouyang, Yuxuan Liao, Zhiyao Ma, Deyang Kong, Xue Feng | Summary: The photonic Ising machine is a new paradigm of optical computing that takes advantage of the unique properties of light wave propagation, parallel processing, and low-loss transmission. Thus, the process of solving combinatorial optimization problems […]

High quantum efficiency parametric amplification via hybridized nonlinear optics

Posted by dbos July 8, 2022Cornell

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Dylan Heberle, Jiaoyang Zheng, Devin J. Dean, Connor Davis | Summary: Parametric amplifiers have allowed breakthroughs in ultrafast, strong-field, and high-energy density laser science and are an essential tool for extending the frequency range of powerful emerging diode-pumped solid-state laser technology. However, their impact is […]

LyC escape from SPHINX galaxies in the Epoch of Reionization

Posted by dbos July 7, 2022Cambridge

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Joakim Rosdahl, Jérémy Blaizot, Harley Katz, Taysun Kimm, Thibault Garel | Summary: We measure escape fractions, $f_{rm esc}$, of ionizing radiation from galaxies in the SPHINX suite of cosmological radiation-hydrodynamical simulations of reionization, resolving halos with $M_{rm vir} gtrapprox 7.5 times 10^7 M_{odot}$ with a minimum cell […]

Filtering and imaging of frequency-degenerate spin waves using nanopositioning of a single-spin sensor

Posted by dbos July 6, 2022Delft

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Brecht G. Simon, Samer Kurdi, Joris J. Carmiggelt, Michael Borst, Allard Katan | Summary: Nitrogen-vacancy (NV) magnetometry is a new technique for imaging spin waves in magnetic materials. It detects spin waves by their microwave magnetic stray fields, which decay evanescently on the scale of […]

Hard X-ray emission from the eastern jet of SS 433 powering the W50 `Manatee’ nebula: Evidence for particle re-acceleration

Posted by dbos July 1, 2022MIT

Kavli Affiliate: Melania Nynka | First 5 Authors: Samar Safi-Harb, Brydyn Mac Intyre, Shuo Zhang, Isaac Pope, Shuhan Zhang | Summary: We present a broadband X-ray study of W50 (`the Manatee nebula’), the complex region powered by the microquasar SS 433, that provides a test-bed for several important astrophysical processes. The W50 nebula, a Galactic […]

First Evaluation of Meson and $τ$ lepton Spectra and Search for Heavy Neutral Leptons at ILC Beam Dump

Posted by dbos Tokyo

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Mihoko M. Nojiri, Yasuihito Sakaki, Kohsaku Tobioka, Daiki Ueda, | Summary: A beam dump experiment can be seamlessly added to the {proposed} International Linear Collider (ILC) program because the high energy electron beam should be dumped after the collision point. The ILC beam dump experiment will […]

Searching for ultralight scalar dark matter with muonium and muonic atoms

Posted by dbos June 22, 2022Tokyo

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Yevgeny V. Stadnik, , , , | Summary: Ultralight scalar dark matter may induce apparent oscillations of the muon mass, which may be directly probed via temporal shifts in the spectra of muonium and muonic atoms. Existing datasets and ongoing spectroscopy measurements with muonium are capable […]
