Edge supercurrent reveals competing electron-pairing mechanisms in a topological superconductor
Jan. 16, 2024
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.

This September marked the end of the first five years of research for the Institute for Research and Innovation in Software for High Energy Physics (IRIS-HEP). In mid-month, an international cohort of the software collaboration’s researchers and project team gathered in Madison, Wisconsin for an all-hands…

'Sudden death' of quantum fluctuations defies current theories of superconductivity
Jan. 10, 2024
Written by Tom Garlinghouse for the Department of Physics

Princeton physicists developed a new experimental approach that precisely detects quantum mechanical fluctuations on the verge of a phase transition of a two-dimensional superconductor. The results uncover a new type of quantum phase transition that cannot be explained by the established theories used to describe phase transitions in superconductors. This research promises to propel the study of quantum condensed matter and superconductivity in new directions.

Leveraging language models for fusion energy research
Dec. 22, 2023
Written by Colton Poore, Andlinger Center for Energy and the Environment

Since the advent of fusion research, scientists have published thousands of documents on the subject — papers, conference proceedings, and even written logs from previous experiments at fusion reactors around the world. Such a wellspring of information would easily take a lifetime to read, and even longer to comprehend.

Physicists ‘entangle’ individual molecules for the first time, bringing about a new platform for quantum science
Dec. 7, 2023
Written by Tom Garlinghouse for the Department of Physics

For the first time, a team of Princeton physicists have been able to link together individual molecules into special states that are quantum mechanically “entangled.” In these bizarre states, the molecules remain correlated with each other—and can interact simultaneously—even if they are miles apart, or indeed, even if they occupy opposite ends of the universe. This research was recently published in the journal Science.

Moore Foundation Grant will fund development of microscope to zoom in on molecules within cells

Written by Wendy Plump, Department of Chemistry

In a funding venture that could be transformational for imaging single molecules within a cell, the Gordon and Betty Moore Foundation has awarded a $3.4M grant to a collaboration between Princeton’s Departments of Chemistry and Molecular Biology.

The four-year grant supports the development of a new microscope that will enable…

How do you make a robot smarter? Program it to know what it doesn’t know.
Nov. 29, 2023
Written by Molly Sharlach, Office of Engineering Communications

Modern robots know how to sense their environment and respond to language, but what they don’t know is often more important than what they do know. Teaching robots to ask for help is key to making them safer and more efficient.

Engineers at Princeton University and Google have come up with a new way to teach robots to know when they…

A new route to a quantum internet
Aug. 31, 2023
Written by Scott Lyon, Office of Engineering Communications

While today’s classical data signals can get amplified across a city or an ocean, quantum signals cannot. They must be repeated in intervals — that is, stopped, copied and passed on by specialized machines called quantum repeaters. Many experts believe these quantum repeaters will play a key role in future communication networks, allowing…
