Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers have designed a material that makes it much easier to distinguish the particles.
The first potential indication of direct detection of dark matter -- something that has been a mystery in physics for over 30 years -- has been attained. Astronomers found what appears to be a signature of 'axions', predicted 'dark matter' particle candidates.
Two research teams working in the same laboratories have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits" -- the building blocks for quantum computers -- that each process quantum data with an accuracy above 99%.
A new study has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. Glass hangs in a metastable state in which the energy of the system is higher than the lowest-energy state the system could assume, a crystalline state. But its state is stable enough at room temperature to last a human lifetime.
Protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons. Researchers have now shown for the first time that this phenomenon exists in nuclei heavier than carbon, including aluminum, iron and lead and also surprisingly allows a greater fraction of protons than neutrons to have high momentum in these neutron-rich nuclei, contrary to long-accepted theories and with implications for ultra-cold atomic gas systems and neutron stars.
Engineers have shown a new way to reverse or eliminate loss by, ironically, adding loss to a laser system to actually reap energy gains. To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now engineers have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they've invented a way to win by losing.
