A new way to make laser-like beams using 250x less power (Correction)
With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a ...
Quantum test strengthens support for EPR steering
Measurement at Big Bang conditions confirms lithium problem
The field of astrophysics has a stubborn problem and it's called lithium. The quantities of lithium predicted to have resulted from the Big Bang are not actually present in stars. But the calculations are ...
SIMP v WIMP: Novel thermal relic mechanism for dark matter creation in the early universe
Micro-macro entangled 'cat states' could one day test quantum gravity
Experiment with speeding ions verifies relativistic time dilation to new level of precision
Superconductivity in orbit: Scientists find new path to loss-free electricity
(Phys.org) —Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor ...
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.
First indirect evidence of so-far undetected strange baryons
(Phys.org) —New supercomputing calculations provide the first evidence that particles predicted by the theory of quark-gluon interactions but never before observed are being produced in heavy-ion collisions ...
Big Bang breakthrough team allows they may be wrong
American astrophysicists who announced just months ago what they deemed a breakthrough in confirming how the universe was born now admit they may have got it wrong.
Multiphysics invisibility cloak manipulates both electric current and heat
Step lightly: All-optical transistor triggered by single photon promises advances in quantum applications
Theoretical device could bring practical spintronics closer to reality
One of the major hurdles in the development of faster electronic devices is the amount of heat produced by silicon microchips. This heat is created by the transport of electrical charges through transistors. ...
How iron feels the heat
As you heat up a piece of iron, the arrangement of the iron atoms changes several times before melting. This unusual behavior is one reason why steel, in which iron plays a starring role, is so sturdy and ...
