Understanding a new kind of magnetism
Using low-frequency laser pulses, a team of researchers has carried out the first measurements that reveal the detailed characteristics of a unique kind of magnetism found in a mineral called herbertsmithite.
Mathematicians offer unified theory of dark matter, dark energy, altering Einstein field equations
(Phys.org)—A pair of mathematicians—one from Indiana University and the other from Sichuan University in China—have proposed a unified theory of dark matter and dark energy that alters Einstein's equations ...
Scientists cast doubt on renowned uncertainty principle
Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. In its most familiar form, it says that it is impossible to measure ...
Time reversal: A simple particle could reveal new physics
(PhysOrg.com) -- A simple atomic nucleus could reveal properties associated with the mysterious phenomenon known as time reversal and lead to an explanation for one of the greatest mysteries of physics: the ...
Physicists show self-correcting quantum computers are theoretically possible
3 Questions: Steven Nahn on the elusive Higgs boson
(PhysOrg.com) -- Troubles at the Large Hadron Collider have led some physicists to suggest the Higgs boson is sabotaging its own discovery. Nahn explains why he disagrees.
Physicists explain why superconductors fail to produce super currents
When high-temperature superconductors were first announced in the late 1980s, it was thought that they would lead to ultra-efficient magnetic trains and other paradigm-shifting technologies.
An unlikely competitor for diamond as the best thermal conductor
An unlikely material, cubic boron arsenide, could deliver an extraordinarily high thermal conductivity – on par with the industry standard set by costly diamond – researchers report in the current issue of the journal ...
