Physicists in the College of Arts and Sciences at Syracuse University have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks.
Princeton physicist Zahid Hasan led an international team of physicists who have discovered a form of chiral crystals -- crystals with an asymmetry like biological "handedness" -- that host slow light-like massless electrons. The movement of some groups of electrons in these crystals mimics the behavior of magnetic monopoles. These strange properties may be utilized for next-generation quantum, magnetic and optical technologies.
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
Scientists at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences recently revealed hydroxyl super rotors from water photochemistry by using the Dalian Coherent Light Source. The researchers, under the direction of Professor YUAN Kaijun and Professor YANG Xueming, published their findings in Nature Communications.
New data from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) add detail -- and complexity -- to an intriguing puzzle that scientists have been seeking to solve: how the building blocks that make up a proton contribute to its spin. The results reveal that different 'flavors' of antiquarks contribute differently to the proton's overall spin -- and in a way that's opposite to those flavors' relative abundance.
Scientists from the Higher School of Economics and Yandex have developed a method that accelerates the simulation of processes at the Large Hadron Collider. The research findings were published in Nuclear Instruments and Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment.
Researchers from the Russia teamed up with colleagues from the US and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past.
A new study published in Physical Review Letters by Prof. Shashua's computer science doctoral students at Hebrew University has demonstrated mathematically that algorithms based on deep neural networks can be applied to better understand the world of quantum physics, as well.
For the first time, researchers at the University of Rochester's Laboratory for Laser Energetics (LLE) have found a way to turn a liquid metal into a plasma and to observe the temperature where a liquid under high-density conditions crosses over to a plasma state. Their observations, published in Physical Review Letters, have implications for better understanding stars and planets and could aid in the realization of controlled nuclear fusion -- a promising alternative energy source whose realization has eluded scientists for decades.
A team of researchers led by DOE's Lawrence Berkeley National Laboratory has developed a simple method that could turn ordinary semiconducting materials into quantum machines -- superthin devices marked by extraordinary electronic behavior that could help to revolutionize a number of industries aiming for energy-efficient electronic systems -- and provide a platform for exotic new physics.
