SIMP v WIMP: Novel thermal relic mechanism for dark matter creation in the early universe
Hackers begone: Measurement-device-independent QKD increases clock rate and transmission distance while reducing failure
Scanning tunnelling microscopy: Computer simulations sharpen insights into molecules
The resolution of scanning tunnelling microscopes can be improved dramatically by attaching small molecules or atoms to their tip. The resulting images were the first to show the geometric structure of molecules ...
The mysterious 'action at a distance' between liquid containers
For several years, it has been known that superfluid helium housed in reservoirs located next to each other acts collectively, even when the channels connecting the reservoirs are too narrow and too long ...
Researchers find qubits based on trapped ions offer a promising scalable platform for quantum computing
Study details laser pulse effects on behavior of electrons
By solving a six-dimensional equation that had previously stymied researchers, University of Nebraska-Lincoln physicists have pinpointed the characteristics of a laser pulse that yields electron behavior ...
Vibrations reveal how material 'takes a breath'
A combination of supercomputer calculations and a bombardment of high-energy particles has revealed how a new kind of material opens its pores and 'breathes'.
Multiphysics invisibility cloak manipulates both electric current and heat
Physicists study magnetism with the roles of position and momentum reversed
Unravelling the mystery of gamma-ray bursts
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'.
LHCb experiment observes two new baryon particles never seen before
(Phys.org) —Today the collaboration for the LHCb experiment at CERN's Large Hadron Collider announced the discovery of two new particles in the baryon family. The particles, known as the Xi_b'- and Xi_b*- ...
Paramecia need Newton for navigation
While single-celled paramecia have the ability to respond to certain external stimuli, they appear not to use that sensory system for simple navigation, new research finds. The work suggests that the ability ...
Atomic clocks prove the stability of a fundamental physical constant
Are the fundamental constants really constant? Recent investigations carried out at the Physikalisch-Technische Bundesanstalt (PTB) have shown that one essential fundamental constant – namely the mass ratio ...
Gravity may have saved the universe after the Big Bang, say researchers
(Phys.org) —New research by a team of European physicists could explain why the universe did not collapse immediately after the Big Bang.
