Scientists using the STAR detector to study particle collisions at the Relativistic Heavy Ion Collider (RHIC) have found an intriguing dip in their data in a relatively unexplored region of the nuclear phase diagram—a map ...
For decades, physicists have searched for dark matter, the invisible substance thought to make up roughly 85% of all matter in the universe. Although its gravitational influence shapes galaxies and the large-scale structure ...
Tiny, soft polymer particles—known as microgels—can help to stabilize extremely thin liquid jets. How this works is the finding of a study led by researchers at TU Darmstadt, which has been published in Nature Communications. ...
Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as "ghostly" for ...
One of the central ideas in modern physics is the phase transition—a sudden transformation of the state of a material. We encounter phase transitions throughout everyday life: water freezes into ice, wax melts in the warmth ...
Aerosols have a profound influence on air quality, human health, clouds and climate, but new particle formation in the atmosphere has remained a scientific conundrum. Large fractions of airborne fine particulate matter consist ...
Carnegie Mellon University scientists have uncovered a new phenomenon that challenges a longstanding assumption about how electronic materials respond to magnetic fields. The discovery broadens the fundamental understanding ...
Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in ...
The most common scientific approach for thinking about how condensation, freezing and other phase transitions begin is based in classical nucleation theory, which was developed about a century ago. Thousands of experiments ...
In a study published in Nature on Aug. 19, a research team has enhanced superconductivity through vacuum fluctuations for the first time. The achievement marks a significant advance in controlling quantum states of matter.
