Kavli Affiliate: Giordano Scappucci | Summary:Orbital energy splittings are important quantum dot parameters for the operation of hole spin qubits. They are known to depend on the lateral confinement of the quantum dots. However, when changing top, plunger gate voltages, which are the typical control parameter for qubit applications, such energy splitting changes are typically […]
Kavli Affiliate: David Charbonneau | Summary:TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant planets ($rm P_b=82.7$ days, $rm P_c=482.8$ days) orbiting an early K dwarf. In this work, we refine the orbital parameters of the […]
Kavli Affiliate: Ulrich Wiesner | Summary:This work realizes a three-dimensionally (3D) nanoarchitected, all organic, "self-separating" lithium-ion electrochemical energy storage (EES) device that is cycled as a solid-state full cell. The device is enabled by a monolithic carbon anode with a co-continuous pore network, derived from the structure direction of resols by an ultra-large molar mass […]
Kavli Affiliate: Giordano Scappucci | Summary:Charge separation from the $(4,0)$ to the $(3,1)$ state in a Si/SiGe double quantum dot is commonly used for initialization of spin qubits and Pauli-spin-blockade readout. It was used in recent experiments involving creation of the $(3,1)$ singlet, and subsequent shuttling of one of the electrons. We present a theoretical […]
Kavli Affiliate: Jinyi Shangguan | Summary:The upcoming imaging survey of the Chinese Space-station Survey Telescope (CSST) will deliver high-resolution imaging of an unprecedented number of galaxies for galaxy studies. To understand CSST’s capability, and to support the preparation of early-science programs, we generate 470,526 mock CSST images for 22,406 simulated galaxies with $M_*>10^9 M_odot$, whose […]
Kavli Affiliate: Wei Gao| Summary:The SVOM Visible Telescope (VT) is critical for the rapid identification of gamma-ray burst (GRB) optical counterparts, particularly for high-redshift candidates that require immediate infrared spectroscopic follow-up. To address the stringent bandwidth constraints of the VHF downlink while ensuring real-time data availability, we developed the VT Onboard Data Processing Pipeline (VOPP).This […]
Kavli Affiliate: Wei Gao| Summary:This paper presents pre-launch testing and calibration results for the SVOM/VT (Space-based Variable Objects Monitor, Visible Telescope) Flight Model (FM), validating its performance under simulated space conditions through thermal vacuum cycling, energy concentration analysis, stray light suppression, and CCD/electronics calibrations (gain, noise, quantum efficiency). The results confirm full compliance with design […]
Kavli Affiliate: Wei Gao| Summary:The 44-cm Visible Telescope (VT) aboard the Space-based Variable Objects Monitor (SVOM) is a dual-band (400-650 nm and 650-1000 nm) instrument designed to detect and characterize the optical counterparts of gamma-ray bursts (GRBs) and other high-energy transients. This paper presents the VT’s design, scientific objectives, observing strategies, and both space- and […]
Kavli Affiliate: Robert E. Clark | Authors: Robert Clark, Louis G. Smith, Matthew P. Leighton, Ryan J. Szukalo, Syma Khalid, Pablo G. Debenedetti, Pilar Cossio, Miro A. Astore and Sonya M. Hanson | Summary: Single-particle cryogenic electron microscopy (cryo-EM) has enabled near-atomic resolution structure determination of diverse biomolecules. Because the high vacuum required for electron […]
Kavli Affiliate: Erich Jarvis | Authors: Chul Lee, Matthew H Davenport and Erich D Jarvis | Summary: Human speech likely arose from regulatory changes for speech-related brain regions, yet causal variants and mechanisms remain unclear. RBFOX1 is a prime candidate, showing specialized expression in vocal learning circuits of human and zebra finch brains and carrying […]
