Room temperature reactive sputtering deposition of titanium nitride with high sheet kinetic inductance

Posted by klaurent September 17, 2025Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Juliang Li, Juliang Li, , , | Summary: Superconducting thin films with high intrinsic kinetic inductance $L_k$ are important for high-sensitivity detectors, enabling strong coupling in hybrid quantum systems, and enhancing nonlinearities in quantum devices. We report the room-temperature reactive sputtering of titanium nitride thin films with […]

Wan-Animate: Unified Character Animation and Replacement with Holistic Replication

Posted by klaurent September 17, 2025September 29, 2025Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Gang Cheng, Gang Cheng, , , | Summary: We introduce Wan-Animate, a unified framework for character animation and replacement. Given a character image and a reference video, Wan-Animate can animate the character by precisely replicating the expressions and movements of the character in the video to generate […]

Improving cosmological reach of a gravitational wave observatory using Deep Loop Shaping

Posted by klaurent September 17, 2025September 29, 2025Caltech

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: , , , , | Summary: Improved low-frequency sensitivity of gravitational wave observatories would unlock study of intermediate-mass black hole mergers, binary black hole eccentricity, and provide early warnings for multi-messenger observations of binary neutron star mergers. Today’s mirror stabilization control injects harmful noise, constituting a […]

Improved systematic evaluation of a strontium optical clock with uncertainty below $1times 10^-18$

Posted by klaurent September 17, 2025September 29, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zhi-Peng Jia, Zhi-Peng Jia, , , | Summary: We report a systematic uncertainty of $9.2times 10^-19$ for the USTC Sr1 optical lattice clock, achieving accuracy at the level required for the roadmap of the redefinition of the SI second. A finite-element model with it in situ-validated, spatially-resolved […]

Scientific Objectives of the Xue-shan-mu-chang 15-meter Submillimeter Telescope

Posted by klaurent September 17, 2025Peking

Kavli Affiliate: Gregory Herczeg | First 5 Authors: , , , , | Summary: Submillimeter astronomy is poised to revolutionize our understanding of the Universe by revealing cosmic phenomena hidden from optical and near-infrared observations, particularly those associated with interstellar dust, molecular gas, and star formation. The Xue-shan-mu-chang 15-meter submillimeter telescope (XSMT-15m), to be constructed […]

Separating the control of moving and holding still in post-stroke arm paresis

Posted by klaurent September 17, 2025September 29, 2025Hopkins

Kavli Affiliate: Reza Shadmehr | Authors: Alkis M. Hadjiosif, Kahori Kita, Scott T. Albert, Robert A. Scheidt, Reza Shadmehr and John W. Krakauer | Summary: Moving and holding still have been posited to be under separate control regimes for both eye and arm movements. The paretic arm after stroke is notable for abnormalities both at […]

10-W Sub-100-fs Ultrafast Cr:ZnS/ZnSe MOPA System enabled by doping gradient engineering

Posted by klaurent September 17, 2025September 29, 2025UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Guangzi Feng, Guangzi Feng, , , | Summary: We report on a high-power mid-infrared femtosecond master oscillator power amplifier (MOPA) system, employing Cr:ZnS and Cr:ZnSe polycrystals with fine-tuned doping profiles. Based on the soft-aperture Kerr-lens mode-locking in the soliton regime, the seed oscillator generates ~40-fs pulses with […]

Aeos is Mixing it Up: The (In)homogeneity of Metal Mixing Following Population III Star Formation

Posted by klaurent September 16, 2025MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Jennifer Mead, Jennifer Mead, , , | Summary: Stellar surface abundances are records of the state of the gas from which stars formed, and thus trace how individual elements have mixed into the surrounding medium following their ejection from stars. In this work, we test the common […]
