Mallika Randeria, who earned her Ph.D. in physics in 2019, observed how electrons behave in a collective manner — aligning themselves in the same direction due to the laws of quantum mechanics — when subjected to a high magnetic field and very low temperature.
Mallika Randeria captures images of the quantum world
As a graduate student, Mallika Randeria conducted experiments to peer deep into the world of quantum physics. Continue Reading →
The red-tinged peaks indicate cobalt atoms, which were added to an iron-based superconductor to study its properties.
Princeton scientists discover surprising quantum effect in an exotic superconductor
Superconductors are already in use in various capacities, but newer iron-based superconductors are an active area of investigation. Researchers led by a Princeton team have studied what happens to the superconducting nature of these materials when impurities are added. The results shed light on how superconductivity behaves in these materials Continue Reading →
Researchers at Princeton explored electrons in a magnetic material at room temperature and discovered that they engage in collective quantum behaviors called Weyl loops.
Left: Distribution of electrons on the surface of the topological quantum magnet. The sharp light-colored features are the quantum Weyl loops. Middle: A theoretical calculation related to the system's response to applied electromagnetic fields. The correspondence between the top and middle images reflects that the quantum Weyl loops are at the heart of the exotic electromagnetic properties of the topological quantum magnet.
Right: Photoemission spectroscopy snapshot of the quantum Weyl loops.

A quantum magnet with a topological twist
Taking their name from an intricate Japanese basket pattern, kagome magnets are thought to have electronic properties that could be valuable for future quantum devices and applications. Theories predict that some electrons in these materials Continue Reading →
Controllable electron flow in quantum wires
Princeton University researchers have demonstrated a new way of making controllable “quantum wires” in the presence of a magnetic field, according to a new study published online today in the journal Nature. The researchers detected channels Continue Reading →
Going quantum to unlock plants’ secrets
By Kevin McElwee When it comes to green living, nobody does it better than plants. When plants convert light into fuel through photosynthesis, not a single particle of light is wasted. If we could unlock Continue Reading →
Discovery provides a path to safe, clean, plentiful energy
By John Greenwald Fusion — the energy-producing reaction that powers our sun and most stars — can be a safe, clean and virtually limitless source for generating electricity on Earth, ending reliance on fossil fuels and Continue Reading →
The Princeton Plasma Physics Laboratory: The quest for clean energy continues
FUSION — the energy-making process that powers the sun — could provide us with a near limitless source of energy, ending our dependence on fossil fuels for making electricity. This summer, after a nearly three-year Continue Reading →
Elusive particles found
IN THE PAST YEAR, PRINCETON PHYSICISTS have detected two particles that were predicted decades ago to exist but had not been found until now. Both particles were detected using a scanning-tunneling microscope to image the Continue Reading →
A farewell to arms? New technique could aid nuclear disarmament
SCIENTISTS at Princeton University and the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) are developing a system to verify the presence of nuclear warheads without collecting classified information, as a step toward the Continue Reading →
