Chaos could improve performance of wireless communication systems
New study advances quest for better superconducting materials
Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors.
Searching for a twist in neutron spin axis, physicists find nothing—and that's something
(Phys.org) —Besides understanding how much dark matter and dark energy there is—about 95 percent of the universe—scientists also want to know more about what dark matter and dark energy are not, as ...
Scientists use plasma shaping to control turbulence in stellarators
Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute of Plasma Physics in Germany have devised a new method for minimizing turbulence in bumpy ...
Muscles act as metamaterials due to collective behavior, physicists show
The solar wind breaks through the Earth's magnetic field
Space is not empty. A wind of charged particles blows outwards from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the Earth's magnetic field. Researchers at the Swedish ...
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.
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published ...
The origins of handedness in life
Shape from sound: New methods to probe the universe
(Phys.org) —As the universe expands, it is continually subjected to energy shifts, or "quantum fluctuations," that send out little pulses of "sound" into the fabric of spacetime. In fact, the universe is thought to have ...
Researchers prove quantum algorithm works by solving linear equations on a quantum computer
Pressure transforms a semiconductor into a new state of matter
(Phys.org) —By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a "topological insulator" (TI), an intriguing state of matter in which a material's interior ...
Physicists publish observation of the 'Charming Socialites'
Protons and neutrons, the particles in an atomic nucleus, are made of smaller pieces called "quarks." Some types of quarks can form particles that exhibit surprising behaviors. Mark Mattson, Ph.D., assistant ...
