Kavli Affiliate: Ethan D. Karpel | First 5 Authors: The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi, Peter Ade, James Aguirre | Summary: The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough discoveries in fundamental physics, […]
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: Patricia R. Burchat | First 5 Authors: Sowmya Kamath, Joshua E. Meyers, Patricia R. 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 […]
Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Tine Curk, James Daniel Farrell, Jure Dobnikar, Rudolf Podgornik, | Summary: Although the free energy of a genome packing into a virus is dominated by DNA-DNA interactions, ordering of the DNA inside the capsid is elasticity-driven, suggesting general solutions with DNA organized into spool-like domains. Using analytical […]
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: Michael L. Roukes | First 5 Authors: Gregory Wimsatt, Olli-Pentti Saira, Alexander B. Boyd, Matthew H. Matheny, Siyuan Han | Summary: We experimentally demonstrate that highly structured distributions of work emerge during even the simple task of erasing a single bit. These are signatures of a refined suite of time-reversal symmetries in distinct […]
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 […]
