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 ...
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.
Miracle material graphene could deliver Internet one hundred times faster
(Phys.org) —The use of graphene in telecommunications could dramatically accelerate internet speeds by up to a hundred times, according to new research by scientists in our Department of Physics.
Researchers find orange manganese-doped quantum dots made up of many colors
Complex activity patterns emerge from simple underlying laws
A new study from researchers at Uppsala University and University of Havana uses mathematic modeling and experiments on ants to show that a group is capable of developing flexible resource management strategies and characteristic ...
Researchers propose new method for achieving nonlinear optical effects
Picture two light beams intersecting one another in space. When the beams touch one another, does the light bend? Reflect? Combine into a single beam?
Researchers prove quantum algorithm works by solving linear equations on a quantum computer
Pendulum swings back on 350-year-old mathematical mystery
(Phys.org) —A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, University of Pittsburgh researchers ...
Computer simulations shed light on how immune cells identify foreign antigens
How do immune cells manage to sort through vast numbers of similar-looking proteins within the body to detect foreign invaders and fight infections? McGill researchers used computational tools to examine what kind of solutions ...
Tiny bubbles in your metallic glass may not be a cause for celebration
Bubbles in a champagne glass may add a festive fizz to the drink, but microscopic bubbles that form in a material called metallic glass can signal serious trouble. In this normally high-strength material, bubbles may indicate ...
Entanglement in a flash (w/ video)
(Phys.org) —JQI researchers under the direction of Chris Monroe have produced quantum entanglement between a single atom's motion and its spin state thousands of times faster than previously reported, demonstrating unprecedented ...
Cool electron acceleration
Physicists from the Max-Planck-Institute of Quantum Optics produced electron pulses from a laser accelerator whose individual particles all have nearly the same, tuneable energy.
