Mathematical scientist suggests possible test for existence of axions
Physicists suggest theory versus observational differences in the sun could be due to dark matter
Universe may face a darker future
New research offers a novel insight into the nature of dark matter and dark energy and what the future of our Universe might be.
Atoms queue up for quantum computer networks
In order to develop future quantum computer networks, it is necessary to hold a known number of atoms and read them without them disappearing. To do this, researchers from the Niels Bohr Institute have developed ...
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 approach enhances quantum-based secure communication
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Researchers design first battery-powered invisibility cloak
Researchers at The University of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.
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 ...
Researchers make magnetic graphene
Graphene, a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice, has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic ...
Photon 'afterglow' could transmit information without transmitting energy
Fusion instabilities lessened by unexpected effect
(Phys.org) —A surprising effect created by a 19th century device called a Helmholz coil offers clues about how to achieve controlled nuclear fusion at Sandia National Laboratories' powerful Z machine.
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 ...
Team finds 'tipping point' between quantum and classical worlds
If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons - the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's ...
