Kavli Affiliate: Abigail Vieregg | First 5 Authors: Stephanie Wissel, Andrés Romero-Wolf, Harm Schoorlemmer, Washington R. Carvalho Jr., Jaime Alvarez-Muñiz | Summary: Tau neutrinos are expected to comprise roughly one third of both the astrophysical and cosmogenic neutrino flux, but currently the flavor ratio is poorly constrained and the expected flux at energies above $10^{17}$ […]
Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Mariano Cababie, Gustavo Cancelo, Luke Chaplinsky | Summary: We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for dark-matter searches. Using 24 days of data acquired in […]
Kavli Affiliate: David Spergel | First 5 Authors: Neelima Sehgal, Simone Aiola, Yashar Akrami, Kaustuv moni Basu, Michael Boylan-Kolchin | Summary: CMB-HD is a proposed ultra-deep (0.5 uk-arcmin), high-resolution (15 arcseconds) millimeter-wave survey over half the sky that would answer many outstanding questions in both fundamental physics of the Universe and astrophysics. This survey would […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Yulong Dong, Xiang Meng, K. Birgitta Whaley, Lin Lin, | Summary: Quantum signal processing (QSP) is a powerful quantum algorithm to exactly implement matrix polynomials on quantum computers. Asymptotic analysis of quantum algorithms based on QSP has shown that asymptotically optimal results can in principle be […]
Kavli Affiliate: Ankit Disa | First 5 Authors: Ankit S. Disa, Michael Fechner, Tobia F. Nova, Biaolong Liu, Michael Först | Summary: Strain engineering is widely used to manipulate the electronic and magnetic properties of complex materials. An attractive route to control magnetism with strain is provided by the piezomagnetic effect, whereby the staggered spin […]
Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Jeffrey A. Harvey, , , , | Summary: Ramanujan influenced many areas of mathematics, but his work on q-series, on the growth of coefficients of modular forms, and on mock modular forms stands out for its depth and breadth of applications. I will give a brief […]
Kavli Affiliate: Karen Byrum | First 5 Authors: Kevork Abazajian, Graeme Addison, Peter Adshead, Zeeshan Ahmed, Steven W. Allen | Summary: We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consideration by the 2020 Decadal Survey. | Search Query: ArXiv Query: […]
Kavli Affiliate: Richard D. Robinson | First 5 Authors: Douglas R. Nevers, Curtis B. Williamson, Benjamin H. Savitzky, Ido Hadar, Uri Banin | Summary: Magic-sized clusters (MSCs) are renowned for their identical size and closed-shell stability that inhibit conventional nanoparticle (NP) growth processes. Though MSCs have been of increasing interest, understanding the reaction pathways toward […]
Kavli Affiliate: Richard D. Robinson | First 5 Authors: Curtis B. Williamson, Douglas R. Nevers, Andrew Nelson, Ido Hadar, Uri Banin | Summary: Structural transformations in molecules and solids have generally been studied in isolation, while intermediate systems have eluded characterization. We show that a pair of CdS cluster isomers provides an advantageous experimental platform […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I describe a modification to the original Fast Multipole Method (FMM) of Greengard & Rokhlin that approximates the gravitation field of an FMM cell as a small uniform grid (a "gridlet") of effective masses. The effective masses on a […]
