Kavli Affiliate: David N. Spergel | First 5 Authors: Oliver H. E. Philcox, Morgane J. König, Stephon Alexander, David N. Spergel, | Summary: The shapes of galaxies trace scalar physics in the late-Universe through the large-scale gravitational potential. Are they also sensitive to higher-spin physics? We present a general study into the observational consequences of […]
Kavli Affiliate: Yukinobu Toda | Summary:We introduce and begin the study of quasi-BPS categories for K3 surfaces, which are a categorical version of the BPS cohomologies for K3 surfaces. We construct semiorthogonal decompositions of derived categories of coherent sheaves on moduli stacks of semistable objects on K3 surfaces, where each summand is a categorical Hall […]
Kavli Affiliate: Yukinobu Toda | Summary:In previous works, we introduced and studied certain categories called quasi-BPS categories associated to symmetric quivers with potential, preprojective algebras, and local surfaces. They have properties reminiscent of BPS invariants/ cohomologies in enumerative geometry, for example they play important roles in categorical wall-crossing formulas. In this paper, we make the […]

Kavli Affiliate: Yukinobu Toda | Summary:We study certain categories associated to symmetric quivers with potential, called quasi-BPS categories. We construct semiorthogonal decompositions of the categories of matrix factorizations for moduli stacks of representations of (framed or unframed) symmetric quivers with potential, where the summands are categorical Hall products of quasi-BPS categories. These results generalize our […]

Peterka, Hillel Adesnik, Na Ji and Liam Paninski | Summary: A number of calcium imaging methods have been developed to monitor the activity of large populations of neurons. […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao Liu, Zeeshan Ahmed, Shawn W. Henderson, Ryan Herbst, Larry Ruckman | Summary: From generation to generation, the maximum RF frequency and sampling rate of the integrated data converters in RF system-on-chip (RFSoC) family devices from Xilinx increases significantly. With the integrated digital mixers and up and […]
Kavli Affiliate: Archana Raja| Summary:Point defects in two-dimensional materials are of key interest for quantum information science. However, the space of possible defects is immense, making the identification of high-performance quantum defects extremely challenging. Here, we perform high-throughput (HT) first-principles computational screening to search for promising quantum defects within WS$_2$, which present localized levels in […]
Kavli Affiliate: David Kleinfeld | Authors: Kui Qian, David Kleinfeld, Beth Friedman and Yoav Freund | Summary: One routine and necessary, yet time-consuming task in neuroanatomy is the annotation of labeled cells relative to the background. Currently, staining and imaging techniques enable the marking of specific cell groups with fluorescent dyes. Modern high throughput scanning […]
Kavli Affiliate: Harry Atwater | Summary:Active metasurfaces, which are arrays of actively tunable resonant elements, can dynamically control the wavefront of the scattered light at a subwavelength scale. To date, most active metasurfaces that enable dynamic wavefront shaping operate in reflection. On the other hand, active metasurfaces operating in transmission are of considerable interest as […]
