Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Quantum field theory in zero spatial dimensions has a rich infrared landscape and a universal ultraviolet, inverting the usual Wilsonian paradigm. For holographic theories this implies a rich landscape of asymptotically AdS$_2$ geometries. Isolating the […]
Kavli Affiliate: Rainer Weiss | Summary:This white paper describes the research and development needed over the next decade to realize "Cosmic Explorer," the U.S. node of a future third-generation detector network that will be capable of observing and characterizing compact gravitational-wave sources to cosmological redshifts. | Search Query: arXiv Query: search_query=au:”Weiss Rainer”&id_list=&start=0&max_results=10Read More
Kavli Affiliate: Karen Byrum | Summary:We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4. | Search Query: arXiv Query: search_query=au:”Byrum Karen”&id_list=&start=0&max_results=10Read More
Kavli Affiliate: Patricia Burchat | Summary:Galaxy color gradients – i.e., spectral energy distributions that vary across the galaxy profile – will impact galaxy shape measurements when the modeled point spread function (PSF) corresponds to that for a galaxy with spatially uniform color. This paper describes the techniques and results of a study of the expected […]

Kavli Affiliate: Scott P. Wakely | Summary:The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of $100,mathrmm^2,mathrmsr$ and to be operated for at least ten years at the Sun-Earth Lagrange Point 2. Compared to existing experiments, it will improve the sensitivity for the observation of new phenomena in cosmic […]
Kavli Affiliate: Stuart Marshall | Summary:We have developed the concept of pathway assembly to explore the amount of extrinsic information required to build an object. To quantify this information in an agnostic way, we present a method to determine the amount of pathway assembly information contained within such an object by deconstructing the object into […]
Kavli Affiliate: Anna V. Shneidman | First 5 Authors: Alireza Shahsafi, Graham Joe, Soeren Brandt, Anna V. Shneidman, Nicholas Stanisic | Summary: Engineered optical absorbers are of substantial interest for applications ranging from stray light reduction to energy conversion. We demonstrate a large-area (centimeter-scale) metamaterial that features near-unity frequency-selective absorption in the mid-infrared wavelength range. […]
Kavli Affiliate: Richard D. Robinson | 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 their nucleation and stabilization is an outstanding issue. In this work, we demonstrate that high concentration synthesis (1000 […]
Kavli Affiliate: Richard D. Robinson | 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 to study isomerization in well-defined atomically precise systems. The clusters coherently interconvert over an est. 1 eV […]
