Kavli Affiliate: Mohammad Mirhosseini | Summary:Chiral quantum emitters interact with light only in one propagation direction, allowing them to be linked into cascaded systems in which photons mediate ordered, long-range interactions. Such systems are predicted to host novel regimes of many-body physics of light and matter. Exploring these regimes requires arrays of identical quantum emitters […]
Kavli Affiliate: Austin Minnich | Summary:The InP high-electron-mobility transistor (HEMT) is indispensable for low-noise amplifiers (LNAs) in radio astronomy and quantum computing. The composition of the $mathrmIn_xGa_1-xAs$ channel in InP HEMT is known to influence the LNA noise performance. However, the various physical mechanisms responsible for noise generation are not fully characterized and understood. Here, […]
Kavli Affiliate: Dimitri Mawet| Summary:We present new Keck/KPIC high-resolution spectroscopic detections of three ultra-hot Jupiters (UHJs) in the $K$ band: WASP-189b ($rm SNR = 7.2$), MASCARA-1b ($rm SNR = 8.6$), and TOI-1518b ($rm SNR = 7.1$), as well as a tentative detection of KELT-9b ($rm SNR = 5.0$). We perform a uniform set of atmospheric […]
Kavli Affiliate: Morteza Gharib| Summary:Tactile sensing is central to how robotic systems interact with the real world, yet current solutions face a tradeoff between sensing area and system complexity. This work investigates metallic ultrasound waveguides as distributed tactile sensors fully interrogated from a single proximal transducer. Using cylindrical indenters, we characterized the acoustic response to […]
Kavli Affiliate: James Bock | Summary:The NASA SPHEREx satellite was launched in 03/2025 to survey the full sky between 0.75 – 5.0 um. The image processing of SPHEREx H2RG detectors includes real-time flagging of transient events during integration. SPHEREx follows a polar orbit passing over the South Atlantic Anomaly (SAA) zone multiple times daily, where […]
Kavli Affiliate: James Bock | Summary:The Tomographic Ionized-carbon Mapping Experiment (TIME) is a line intensity mapping (LIM) instrument that is designed to observe the power spectrum of the [CII] $158$~$μ$m emission line during the Epoch of Reionization. TIME completed a commissioning run in 2022 at the Arizona Radio Observatory onboard the 12-M Radio Telescope at […]

Kavli Affiliate: Wei Gao| Summary:Long-video reasoning is fundamentally constrained by how models acquire and utilize visual evidence. Existing tool-augmented video frameworks often interleave temporal grounding and answer reasoning within a single trajectory, causing early semantic hypotheses to bias evidence localization. We term this failure mode premature semantic commitment, where biased grounding retrieves incomplete evidence and […]
