Interpretable abstractions of artificial neural networks predict behavior and neural activity during human information gathering

Posted by dbos UCSD / Salk

Kavli Affiliate: Marcelo Mattar | Authors: Simone D’Ambrogio, Jan Grohn, Nima Khalighinejad, Marcelo Mattar, Laurence T Hunt and Matthew F Rushworth | Summary: It has been suggested that humans and other animals are driven by a fundamental desire to acquire information about opportunities available in their environments. Not only might such a desire explain pathological […]

Floquet operator dynamics and orthogonal polynomials on the unit circle

Posted by klaurent Caltech

Kavli Affiliate: N. C. Yeh| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Operator spreading under stroboscopic time evolution due to a unitary is studied. An operator Krylov space is constructed and related to orthogonal polynomials on a unit circle (OPUC), as well as to the Krylov space of the edge operator of the Floquet […]

Modeling phase transformations in Mn-rich disordered rocksalt cathodes with machine learning interatomic potentials

Posted by klaurent Berkeley

Kavli Affiliate: Gerbrand Ceder| Summary:Mn-rich disordered rocksalt (DRX) cathode materials exhibit a phase transformation from a disordered to a partially disordered spinel-like structure ($δ$-phase) during electrochemical cycling. In this computational study, we used charge-informed molecular dynamics with a fine-tuned CHGNet foundation potential to investigate the phase transformation in Li$_x$Mn$_0.8$Ti$_0.1$O$_1.9$F$_0.1$. Our results indicate that transition metal […]

Giant Outer Transiting Exoplanet Mass (GOT ‘EM) Survey. VI: Confirmation of a Long-Period Giant Planet Discovered with a Single TESS Transit

Posted by klaurent MIT

Kavli Affiliate: George Ricker | Summary:We report the discovery and confirmation of TOI-4465 b, a $1.25^+0.08_-0.07~R_J$, $5.89pm0.26~M_J$ giant planet orbiting a G dwarf star at $dsimeq$ 122 pc. The planet was detected as a single-transit event in data from Sector 40 of the Transiting Exoplanet Survey Satellite (TESS) mission. Radial velocity (RV) observations of TOI-4465 […]

Hundreds of TESS exoplanets might be larger than we thought

Posted by klaurent MIT

Kavli Affiliate: George Ricker | Summary:The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from the fraction of starlight blocked when a planet transits its host star. The wide-field Transiting Exoplanet Survey Satellite (TESS) has discovered hundreds of new exoplanets, but its low […]

First High-Throughput Evaluation of Dark Matter Detector Materials

Posted by klaurent Berkeley

Kavli Affiliate: Kristin Persson | Summary:We perform the first high-throughput search and evaluation of materials that can serve as excellent low-mass dark matter detectors. Using properties of close to one thousand materials from the Materials Project database, we project the sensitivity in dark matter parameter space for experiments constructed from each material, including both absorption […]

Pair density modulation from glide symmetry breaking and nematic superconductivity

Posted by klaurent Caltech

Kavli Affiliate: Stevan Nadj-Perge | Summary:Pair density modulation is a superconducting state, recently observed in exfoliated iron-based superconductor flakes, in which the superconducting gap oscillates strongly with the same periodicity as the underlying crystalline lattice. We propose a microscopic model that explains this modulation through a combination of glide-mirror symmetry breaking and the emergence of […]
