Kavli Affiliate: Lisa Barsotti | First 5 Authors: Chris Whittle, Kentaro Komori, Dhruva Ganapathy, Lee McCuller, Lisa Barsotti | Summary: Vacuum quantum fluctuations impose a fundamental limit on the sensitivity of gravitational-wave interferometers, which rank among the most sensitive precision measurement devices ever built. The injection of conventional squeezed vacuum reduces quantum noise in one […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Daniel Carney, Gordan Krnjaic, David C. Moore, Cindy A. Regal, Gadi Afek | Summary: Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter. Searching for the extremely weak signals […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The LHCb Collaboration has reported resonant activity in the channel $D^+ K^-$, identifying two components: $X_0(2900)$ with $J^P = 0^+$ at $2866 {pm} 7$ MeV, $Gamma_0=57{pm} 13$ MeV and $X_1(2900)$ with $J^P = 1^-$ at $2904 {pm} […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Mohammad Akhshik, Katherine E. Whitaker, Gabriel Brammer, Guillaume Mahler, Keren Sharon | Summary: We present a novel Bayesian methodology to jointly model photometry and deep Hubble Space Telescope (HST) 2d grism spectroscopy of high-redshift galaxies. Our requiem2d code measures both unresolved and resolved stellar populations, ages, […]
Kavli Affiliate: Robert L. Byer | First 5 Authors: Uwe Niedermayer, Dylan S. Black, Kenneth J. Leedle, Yu Miao, Robert L. Byer | Summary: We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon […]
Kavli Affiliate: Robert Byer | Summary:We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon structures. Unlike previous ballistic optical microbunching demonstrations, we use a modulator-demodulator scheme to compress phase space in the time […]
Kavli Affiliate: Tomoyuki Abe | Summary:Bivariant theory is a unified framework for cohomology and Borel-Moore homology theories. In this paper, we extract an $infty$-enhanced bivariant homology theory from Gaitsgory-Rozenblyum’s six functor formalism. | Search Query: arXiv Query: search_query=au:”Abe Tomoyuki”&id_list=&start=0&max_results=10Read More
Kavli Affiliate: Chiaki Hikage | Summary:We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level order and find that the amplitude of the off-diagonal components from the trispectrum decreases by reconstruction. Using a large set of N-body simulations, we also find […]
Kavli Affiliate: Xian Chen | First 5 Authors: Manuel Arca-Sedda, Pau Amaro-Seoane, Xian Chen, , | Summary: We study the formation of intermediate-mass ratio inspirals (IMRIs) triggered by the interactions between two stellar black holes (BHs) and an intermediate-mass BH (IMBH) inhabiting the centre of a dense star cluster. We exploit $N$-body models varying the […]
Kavli Affiliate: Paul Brink | Summary:We present limits on spin-independent dark matter-nucleon interactions using a $10.6$ $mathrmg$ Si athermal phonon detector with a baseline energy resolution of $σ_E=3.86 pm 0.04$ $(mathrmstat.)^+0.19_-0.00$ $(mathrmsyst.)$ $mathrmeV$. This exclusion analysis sets the most stringent dark matter-nucleon scattering cross-section limits achieved by a cryogenic detector for dark matter particle masses […]
