AI holds the potential to help doctors find early markers of disease and policymakers to avoid decisions that lead to war. But a growing body of evidence has revealed deep flaws in how machine learning is used in science, a problem that has swept through dozens of fields and implicated thousands of erroneous papers.

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computational research, the computer programs used by researchers are sometimes many years old, originally written in outdated programming languages and passed down through several generations of students.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

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.

'Sudden death' of quantum fluctuations defies current theories of superconductivity

Author
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.

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

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.
