Kavli Affiliate: Wei Gao | First 5 Authors: Jinxu Liu, Wei Gao, Zhanyi Hu, , | Summary: Unlike loose coupling approaches and the EKF-based approaches in the literature, we propose an optimization-based visual-inertial SLAM tightly coupled with raw Global Navigation Satellite System (GNSS) measurements, a first attempt of this kind in the literature to our […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Heming Wang, Lue Wu, Zhiquan Yuan, Kerry Vahala, | Summary: Narrow-linewidth lasers are important to many applications spanning precision metrology to sensing systems. Their miniaturization in the form of on-chip lasers is receiving increasing attention. Here, a noise level that is consistent with a fundamental frequency noise […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Jeff Delaune, Jacob Izraelevitz, Larry A. Young, William Rapin, Evgeniy Sklyanskiy | Summary: Mid-Air Deployment (MAD) of a rotorcraft during Entry, Descent and Landing (EDL) on Mars eliminates the need to carry a propulsion or airbag landing system. This reduces the total mass inside the aeroshell by […]

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hung-Tzu Chang, Alexander Guggenmos, Scott K. Cushing, Yang Cui, Naseem Ud Din | Summary: Direct measurements of photoexcited carrier dynamics in nickel are made using few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy at the nickel M$_{2,3}$ edge. It is observed that the core-level absorption lineshape of […]
Kavli Affiliate: James Bock | First 5 Authors: Lionel Duband, Thomas Prouve, James Bock, Lorenzo Moncelsi, Alessandro Schillaci | Summary: In the field of astrophysics, the faint signal from distant galaxies and other dim cosmological sources at millimeter and submillimeter wavelengths require the use of high-sensitivity experiments. Cryogenics and the use of low-temperature detectors are […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Warren Jin, Qi-Fan Yang, Lin Chang, Boqiang Shen, Heming Wang | Summary: Driven by narrow-linewidth bench-top lasers, coherent optical systems spanning optical communications, metrology and sensing provide unrivalled performance. To transfer these capabilities from the laboratory to the real world, a key missing ingredient is a […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Hengjiang Ren, Tirth Shah, Hannes Pfeifer, Christian Brendel, Vittorio Peano | Summary: Recent advances in cavity-optomechanics have now made it possible to use light not just as a passive measuring device of mechanical motion, but also to manipulate the motion of mechanical objects down to the level […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, William S. Whitney, Meir Y. Grajower, Kenji Watanabe, Takashi Taniguchi | Summary: Black phosphorus (BP) offers considerable promise for infrared and visible photonics. Efficient tuning of the bandgap and higher subbands in BP by modulation of the Fermi level or application of vertical electric […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Ioana Craiciu, Mi Lei, Jake Rochman, John G. Bartholomew, Andrei Faraon | Summary: Quantum networks will enable a variety of applications, from secure communication and precision measurements to distributed quantum computing. Storing photonic qubits and controlling their frequency, bandwidth and retrieval time are important functionalities in future […]
