Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor.

The research promises to enhance our understanding of quantum physics in solids in general and also propel the study of quantum condensed matter physics and…

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.

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.

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 researchers…

An international team of astrophysicists including Princeton’s Andy Goulding has discovered the most distant supermassive black hole ever found, using two NASA space telescopes: the Chandra X-ray Observatory (Chandra) and the James Webb Space Telescope (JWST).

The black…

In recognition of the importance to society of innovative research and scholarship, the 2023 Dean for Research Award for Distinguished Innovation will be awarded to Peter Jaffé, William L. Knapp Professor of Civil Engineering and professor of civil and environmental engineering, and Shan Huang, professional specialist in civil and environmental engineering, for the development of bacterial approaches to eliminating harmful contaminants that are persistent in the environment.

A study published in the journal Nature led by Princeton researchers reveals in precise detail how and why a material known as magic-angle twisted bilayer graphene forms insulating quantum phases.

Hydrogen’s potential as a clean fuel could be limited by a chemical reaction in the lower atmosphere, according to research from Princeton University and the National Oceanic and Atmospheric Association.

This is because hydrogen gas easily reacts in the atmosphere with the same molecule primarily responsible for breaking down methane, a…
