Kavli Affiliate: Max Tegmark | Summary:Rapidly improving AI capabilities and autonomy hold significant promise of transformation, but are also driving vigorous debate on how to ensure that AI is safe, i.e., trustworthy, reliable, and secure. Building a trusted ecosystem is therefore essential — it helps people embrace AI with confidence and gives maximal space for […]
Kavli Affiliate: Anthony Challinor | Summary:Noise maps from CMB experiments are generally statistically anisotropic, due to scanning strategies, atmospheric conditions, or instrumental effects. Any mis-modeling of this complex noise can bias the reconstruction of the lensing potential and the measurement of the lensing power spectrum from the observed CMB maps. We introduce a new CMB […]
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 […]
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 […]
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 […]
Kavli Affiliate: Robert Cameron | Summary:The magnetic fields and dynamical processes in the solar polar regions play a crucial role in the solar magnetic cycle and in supplying mass and energy to the fast solar wind, ultimately being vital in controlling solar activities and driving space weather. Despite numerous efforts to explore these regions, to […]
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 […]
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 […]
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 […]
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 […]
