Simple shift could make low Earth orbit satellites high capacity
Sept. 12, 2024

Low-orbit satellites could soon offer millions of people worldwide access to high-speed communications, but the satellites’ potential has been stymied by a technological limitation — their antenna arrays can only manage one user at a time.

The one-to-one ratio means that companies must launch either constellations of many satellites, or…

Author
Written by Allison Gasparini, Center for Statistics and Machine Learning

In laboratories dealing with computational research, the computer programs used by researchers are sometimes many years old, originally written in outdated programming languages and passed down through several generations of students. If a person doesn’t have a background in software development, they may not know how to write code in a way…

Edge supercurrent reveals competing electron-pairing mechanisms in a topological superconductor
Jan. 16, 2024
Author
Written by Tom Garlinghouse for the Department of Physics

Three years ago, scientists discovered evidence of edge supercurrents in the Weyl superconductor molybdenum telluride. Now, Princeton researchers have expanded on that finding and uncovered a series of novel features that may broaden our understanding of topological superconductivity. In the new experiment, the superconducting electrons in molybdenum telluride are forced to coexist with a stronger supercurrent injected from the conventional superconductor niobium.  The competition between the two incompatible superconducting populations leaves a distinctive imprint on oscillations executed by the edge supercurrent in the presence of a magnetic field. The oscillations provide a new window on how electrons behave in the superconducting state. This research, to appear in Nature Physics, deepens our understanding of quantum phenomena in novel materials.
