Published New possibilities in the theoretical prediction of particle interactions
(via sciencedaily.com) A team of scientists finds a way to evaluate highly complex Feynman integrals.
Published Ultrafast beam-steering breakthrough
(via sciencedaily.com) n a major breakthrough in the fields of nanophotonics and ultrafast optics, a research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent light sources.
Published First detection of neutrinos made at a particle collider
(via sciencedaily.com) A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to deepen scientists' understanding of the nature of neutrinos, which are among the most abundant particles in the universe and key to the solution of the question why there is more matter than antimatter.
Published Scientists open door to manipulating 'quantum light'
(via sciencedaily.com) How light interacts with matter has always fired the imagination. Now scientists for the first time have demonstrated the ability to manipulate single and double atoms exhibiting the properties of simulated light emission. This creates prospects for advances in photonic quantum computing and low-intensity medical imaging.
Published Instrument adapted from astronomy observation helps capture singular quantum interference effects
(via sciencedaily.com) By adapting technology used for gamma-ray astronomy, researchers has found X-ray transitions previously thought to have been unpolarized according to atomic physics, are in fact highly polarized.
Published Superconducting amplifiers offer high performance with lower power consumption
(via sciencedaily.com) Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and successfully demonstrated a high-performance cooled amplifier with power consumption three orders of magnitude lower than that of conventional cooled semiconductor amplifiers. This result is expected to contribute to the realization of large-scale multi-element radio cameras and error-tolerant quantum computers, both of which require a large number of low-noise microwave amplifiers.
Published Sculpting quantum materials for the electronics of the future
(via sciencedaily.com) The development of new information and communication technologies poses new challenges to scientists and industry. Designing new quantum materials -- whose exceptional properties stem from quantum physics -- is the most promising way to meet these challenges. An international team has designed a material in which the dynamics of electrons can be controlled by curving the fabric of space in which they evolve. These properties are of interest for next-generation electronic devices, including the optoelectronics of the future.
Published Qubits put new spin on magnetism: Boosting applications of quantum computers
(via sciencedaily.com) Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
Published Displays with more brilliant colors through a fundamental physical concept
(via sciencedaily.com) New research has shown that a strong coupling of light and material increases the colour brilliance of OLED displays. This increase is independent of the viewing angle and does not affect energy efficiency.
Published Breakthrough in the understanding of quantum turbulence
(via sciencedaily.com) Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary. The team's findings demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behavior of fluids and gases like water and air is a key question. Understanding that in classical fluids will help scientists do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. There is a huge number of potential real-world uses for understanding macroscopic turbulence.
Published 'Terminator zones' on distant planets could harbor life
(via sciencedaily.com) In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.
Published Modelling superfast processes in organic solar cell material
(via sciencedaily.com) In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.
Published Filming proteins in motion
(via sciencedaily.com) Proteins are the heavy-lifters of biochemistry. These beefy molecules act as building blocks, receptors, processors, couriers and catalysts. Naturally, scientists have devoted a lot of research to understanding and manipulating proteins.
Published Webb Telescope captures rarely seen prelude to supernova
(via sciencedaily.com) The rare sight of a Wolf-Rayet star -- among the most luminous, most massive, and most briefly detectable stars known -- was one of the first observations made by NASA's James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.
