Impact of Strong Atmospheric Turbulence on Two-Way Optical Time Transfer

May 8, 2023
Author(s)
Laura Sinclair, Emily Caldwell, Jean-Daniel Deschenes, Hugo Bergeron, William C. Swann, Nathan Newbury
Frequency comb based optical time transfer can provide femtosecond-level timing which will support future clock networks. However, for long-distance terrestrial links, non-reciprocal atmospheric turbulence induces a timing penalty. Here, we quantify this

Phosphate-Functionalized MOF-808 for High Performance Li-S Batteries

May 8, 2023
Author(s)
Bingqian Liu, Avery Baumann, Megan Butala, V. Sara Thoi
Lithium–sulfur batteries are promising candidates for next-generation energy storage devices due to their outstanding theoretical energy density. However, they suffer from low sulfur utilization and poor cyclability, greatly limiting their practical

Rydberg Atoms for One-Step Traceability for Sensing Electric Fields

W. L. N. C. Liyanage, Nan Tang, Lizabeth J. Quigley, Julie A. Borchers, Alexander Grutter, Brian B. Maranville, Sunil Sinha, Nicolas Reyren, Sergio A. Montoya, Eric E. Fullerton, Lisa Debeer-Schmitt, Dustin A. Gilbert
Magnetic skyrmions are topologically protected chiral spin structures which present opportunities for next-generation magnetic data storage and logic information technologies. The topology of these structures originates in the geometric configuration of

A field-effect transistor-based room-temperature quantum current source

May 4, 2023
Author(s)
Kin (Charles) Cheung, Barry J O'Sullivan
The work provides a proof-of-concept demonstration of the room-temperature quantum current source based on nanoscale metal-oxide-semiconductor-Field-Effect-Transistor (MOSFET). Using low leakage MOSFET, the current pump achieved 1.00011 ± 0.00022 charges

Guidance on Contactless Friction Ridge Image Compression, v1.0
