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 […]

Searching for Dark Clumps with Gravitational-Wave Detectors

Posted by dbos June 29, 2022Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Sebastian Baum, Michael A. Fedderke, Peter W. Graham, , | Summary: Dark compact objects ("clumps") transiting the Solar System exert accelerations on the test masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of these clump transits in a variety of current and future […]
