(PhysOrg.com) -- “For the first time, fields of study relating both to cold atoms and to the nanoscale have intersected,” Lene Vestergaard Hau tells PhysOrg.com . “Even though both have been active areas of research, cold atoms have not been brought together with nanoscale structures at the single nanometer level.
Quarks exist in a soup of other quarks, antiquarks and gluons within a proton or neutron. Determining their mass has been difficult due to the strong force that binds them together. (Christine Davies/University of Glasgow)
(PhysOrg.com) -- A team of physicists from the University of Glasgow has predicted the mass of a new particle which would help explain one of the fundamental forces of the universe.
One of the great theoretical challenges facing physicists is understanding how the tiniest elementary particles give rise to most of the mass in the visible universe. Tiny particles called quarks and gluons are the building blocks for larger particles such as protons and neutrons, which in turn form atoms. However, quarks and gluons behave very differently than those larger particles, making them more difficult to study.
A new calculation, reported in the January 25, 2008 issue of Physical Review Letters , confirms the six-quark theory of particle-anti-particle asymmetry.
This image of a full-energy collision between gold ions shows the paths taken by thousands of subatomic particles produced during the impact. (PhysOrg.com) -- For a brief instant, it appears, scientists at Brookhaven National Laboratory on Long Island recently discovered a law of nature had been broken.
The diagram above is known as the 3-D chart of the nuclides. The familiar Periodic Table arranges the elements according to their atomic number, Z, which determines the chemical properties of each element. Physicists are also concerned with the N axis, which gives the number of neutrons in the nucleus.
Masahiro Hotta's energy teleportation scheme. (PhysOrg.com) -- Using the same quantum principles that enable the teleportation of information, a new proposal shows how it may be possible to teleport energy.
(PhysOrg.com) -- In a new demonstration of reversible light storage, physicists have achieved storage efficiencies of more than a magnitude greater than those offered by previous techniques.
