Physicist proves impossibility of quantum time crystals
Better insight into molecular interactions
How molecules in biochemical solutions do interact, is a question of great importance for understanding processes in catalysts, functional materials and even in organisms. Until now, scientists could have ...
New theory points to 'zombie vortices' as key step in star formation
(Phys.org) —A new theory by fluid dynamics experts at the University of California, Berkeley, shows how "zombie vortices" help lead to the birth of a new star.
Researchers develop model to help control cascading events
Cosmic turbulences result in star and black hole formation
Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. What we do know is that magnetic fields figure prominently into the picture. ...
Physicists propose Higgs boson 'portal' as the source of this elusive entity
One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. This value is so small, ...
Researchers discover midair collisions enhance the strength of sandstorms
Unruly plasmas: Researchers challenge Bohr-van Leeuwen theorem
Scientists of the universities in Düsseldorf and Kiel have obtained a surprising result that appears to be in conflict with standard text book knowledge. According to the fundamental Bohr-van Leeuwen theorem, ...
A layer of tiny grains can slow sound waves
In some ways, granular material—such as a pile of sand—can behave much like a crystal, with its close-packed grains mimicking the precise, orderly arrangement of crystalline atoms. Now researchers at ...
Model-independent measurement of dark matter mass could lead to future discoveries
Researchers stop and store light for 60 seconds
Blackbody radiation induces attractive force stronger than gravity
The ferromagnetic Kondo effect
A group of physicists that includes scientists of the International School for Advanced Studies (SISSA) of Trieste have shown how to obtain a particular case of a physical effect – so far never observed ...
Ferromagnetic and antiferromagnetic – at the same time
(Phys.org) —Researchers from the Paul Scherrer Institute (PSI) have made thin, crystalline layers of the material LuMnO3 that are both ferromagnetic and antiferromagnetic.
