S. X. Riberolles, Tyler Slade, Rebecca Dally, P. Sarte, Bing Li, Tianxiong Han, H. Lane, C. Stock, H. Bhandari, N. J. Ghimire, D. Abernathy, P. Canfield, Jeffrey Lynn, B. Ueland, R. McQueeney
TbMn 6Sn 6 is a topological ferrimagnet where the uniaxial anisotropy of the Tb 3+ ion generates out-of-plane magnetization of the ferromagnetic Mn kagome layer, resulting in the emergence of a two-dimensional Chern state. TbMn 6Sn 6 is also known to

Reusable Network Simulation for CPS Co-Simulations

May 9, 2023
Author(s)
Himanshu Neema, Harmon Nine, Thomas Roth
Cyber-Physical Systems (CPS) require seamless integration of physical and computation components through communication networks. They often contain sub-systems from different physical domains (e.g., electrical, mechanical, and electronic) that must

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
