Neutrons zero in on the elusive magnetic Majorana fermion
|
|
Anonymous writes:  As neutrons (blue line) scatter off the graphene-like honeycomb material, they produce a magnetic Majorana fermion (green wave) that moves through the material disrupting or breaking apart magnetic interactions between 'spinning' electrons. Credit: ORNL/Jill Hemman
Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that, with a fuller understanding, could pave the way for quantum calculations far beyond the limits of the ones and zeros of a computer's binary code.

Anonymous writes:  A 99.95% certainty
A review of three separate experiments has turned up "remarkably similar"
results, pointing to what researchers say is a strong possibility that
we've found hits of a phenomenon that goes beyond the standard model of
particle physics.
When taken together, data from experiments conducted in the US,
Switzerland, and Japan, have yielded a result with 99.95 percent
certainty that lepton universality - a fundamental assumption of the
standard model - does not hold up.
"These studies have resulted in observations that seem to challenge lepton universality," an international team of physicists reports.

Solving one of nature's great puzzles

 Via ScienceDaily.com: Solving one of nature's great puzzles: What drives the accelerating expansion of the universe?
UBC physicists may have solved one of nature's great puzzles: what causes the accelerating expansion of our universe?
PhD student Qingdi Wang has tackled this question in a new study that tries to resolve a major incompatibility issue between two of the most successful theories that explain how our universe works: quantum mechanics and Einstein's theory of general relativity.
The study suggests that if we zoomed in-way in-on the universe, we would realize it's made up of constantly fluctuating space and time.
"Space-time is not as static as it appears, it's constantly moving," said Wang...

 Via BBC-Earth: The physics that tells us what the Universe is made of
Everything around us is made of atoms, but it turns out that the building blocks of the Universe are far stranger than that
Science writer and astrophysicist Adam Becker explains what the Universe is made of to BBC Earth's Michael Marshall and Melissa Hogenboom, with help from the animators at Pomona Pictures.

CERN Declares War On The Standard Model
|
|
 by Matt Williams (UniverseToday.com): Ever since the discovery of the Higgs Boson in 2012, the Large Hadron Collider has been dedicated to searching for the existence of physics that go beyond the Standard Model. To this end, the Large Hardon Collider beauty experiment (LHCb) was established in 1995, specifically for the purpose of exploring what happened after the Big Bang that allowed matter to survive and create the Universe as we know it.
Since that time, the LHCb has been doing some rather amazing things. Since that time, the LHCb has been doing some rather amazing things. This includes discovering five new particles, uncovering evidence of a new manifestation of matter-antimatter asymmetry, and (most recently) discovering unusual results when monitoring beta decay. These findings, which CERN announced in a recent press release, could be an indication of new physics that are not part of the Standard Model.

Maxwell Simmetry gone bye bye?
|

Anonymous writes: 
Radio waves, microwaves and even light itself are all made of electric and magnetic fields. The classical theory of electromagnetism was completed in the 1860s by James Clerk Maxwell. At the time, Maxwell's theory was revolutionary, and provided a unified framework to understand electricity, magnetism and optics. Now, new research led by LSU Department of Physics & Astronomy Assistant Professor Ivan Agullo, with colleagues from the Universidad de Valencia, Spain, advances knowledge of this theory. Their recent discoveries have been published in Physical Review Letters.

This Strange Light Particle Behaviour Challenges Our Understanding of Quantum Th
|

Anonymous writes: 
It's even spookier than we predicted.
Scientists investigating how light particles (or photons) experience entanglement on the quantum scale have discovered something entirely unexpected, and it challenges long-held assumptions about the initial moments of what Einstein referred to as "spooky action at a distance".
When the team created entangled pairs of photons, these particles didn't originate in the same place and break away as predicted - they emerged from entirely different points in space, which means quantum theory might have to account for a whole lot more randomness than we thought.

How did the proton get its spin?
|
|
Anonymous writes:  Calculating a proton's spin used to be an easy college assignment. In fact, Carl Gagliardi remembers answering that question when he was a physics graduate student in the 1970s. But the real answer turned out not to be simple at all. Even Gagliardi's "right" response was disproven by experiments a few years later that turned the field upside-down.
Protons are one of the three particles that make up atoms, the building
blocks of the universe. A proton's spin is one of its most basic
properties. Because protons are in part made up of quarks, scientists
presumed the proton spins were just the sum of the quark spins.

Newly discovered phenomenon accelerates electrons as they enter a viscous state
|
|
Anonymous writes:  A new finding by physicists at MIT and in Israel shows that under certain specialized conditions, electrons can speed through a narrow opening in a piece of metal more easily than traditional theory says is possible.
This "superballistic" flow resembles the behavior of gases flowing through a constricted opening, however it takes place in a quantum-mechanical electron fluid, says MIT physics professor Leonid Levitov, who is the senior author of a paper describing the finding that appears this week in the Proceedings of the National Academy of Sciences.

Internal structure of proton is still a mystery
|
|
Anonymous writes:  OLYMPUS experiment sheds light on structure of protons (from phys.org)
A mystery concerning the structure of protons is a step closer to being solved, thanks to a seven-year experiment led by researchers at MIT.
For many years
researchers have probed the structure of protons—subatomic
particles with a positive charge—by bombarding them with electrons
and examining the intensity of the scattered electrons at different
angles.
In this way they have attempted to determine how the proton's
electric charge and magnetization are distributed. These experiments
had previously led researchers to assume that the electric and
magnetic charge distributions are the same, and that one photon—an
elementary particle of light—is exchanged when the protons interact
with the bombarding electrons.

First Evidence That Superconductivity Can Be Left- or Right Handed
|
|
 Where electricity flows without resistance... but only in one direction.
FIONA MACDONALD/ 28 FEB 2017 (www.sciencealert.com)
Scientists have found the first evidence that superconductivity, one of
the most intriguing and lucrative phenomena in physics, can be left- or
right-handed. Or, more accurately, that superconducting materials can
display chirality.
Chirality is frequently seen in nature
- chiral materials are those that have mirror image versions of
themselves that aren't identical, just like a left and a right hand. But
until now, chirality and superconductivity - the ability for a material
to transmit electricity with zero resistance - had never been found in
the same material.

Scientists have confirmed a brand new form of matter: time crystals
|
|
FIONA MACDONALD (sciencealert.com), 28 JAN 2017/ Perpetual motion without energy.
For months now, there's been speculation
that researchers might have finally created time crystals - strange
crystals that have an atomic structure that repeats not just in space,
but in time, putting them in perpetual motion without energy.
Now it's official - researchers have just reported in detail how to
make and measure these bizarre crystals. And two independent teams of
scientists claim they've actually created time crystals in the lab based
off this blueprint, confirming the existence of an entirely new form of
matter.

Compressed Orbits and the Secret Behind E = mc²
|
|
FDT writes: Input energy is required in order to produce an electron-positron pair from the vacuum.
This might suggest that these particles are being rescued from a low energy level, and that as such there is not very much actual energy being stored in the bound state.
This view changes when we examine how an electron and a positron could possibly be bonded together in a stable lattice in the first place.
This article introduces the very important distinction between a
compressed orbit and an uncompressed orbit, and it is suggested that the
background inertial and luminiferous medium is a store of centrifugal
potential energy.

Physicists have found a metal that conducts electricity but not heat
|
|
Anonymous writes: by FIONA MACDONALD (sciencealert.com), 28 JAN 2017/ Defying one of the most fundamental laws of conductors.
Researchers have identified a metal that conducts electricity without conducting heat - an incredibly useful property that defies our current understanding of how conductors work.
The metal contradicts something called the Wiedemann-Franz Law, which basically states that good conductors of electricity will also be proportionally good conductors of heat, which is why things like motors and appliances get so hot when you use them regularly.
