A team of physicists affiliated with multiple institutions in China has measured a pulse of light in 37 dimensions. In their paper published in Science Advances, the group explains that their experiment was meant to demonstrate that quantum mechanics is more nonclassical than thought. Go to Source Foams are an essential component of many different drinks and foods: from a frothy head of beer to coffee crema, bread and ice cream. Despite their ubiquity, little is actually known or understood about these highly complex systems. Go to Source A collaboration between Nordita, the Nordic Institute for Theoretical Physics, hosted by Stockholm University, KTH and Google Quantum AI explores how gravitational fields influence quantum computing hardware, laying the foundation for advances in quantum sensing. Go to Source Physicists have performed a simulation they say sheds new light on an elusive phenomenon that could determine the ultimate fate of the universe. Go to Source Most metals expand when their temperature rises. The Eiffel Tower, for example, is about 10 to 15 centimeters taller in summer than in winter due to its thermal expansion. However, this effect is extremely undesirable for many technical applications. Go to Source Superconductors can carry electricity without losing energy, a superpower that makes them invaluable for a range of sought-after applications, from maglev trains to quantum computers. Generally, this comes at the price of having to keep them extremely cold, an opportunity cost that has frequently hindered widespread use. Go to Source In order to find rare processes from collider data, scientists use computer algorithms to determine the type and properties of particles based on the faint signals that they leave in the detector. One such particle is the tau lepton, which is produced, for example, in the decay of the Higgs boson. Go to Source […] For the first time, a team of researchers at Lawrence Livermore National Laboratory (LLNL) quantified and rigorously studied the effect of metal strength on accurately modeling coupled metal/high explosive (HE) experiments, shedding light on an elusive variable in an important model for national security and defense applications. Go to Source In physics, the term “isotropy” means a system where the properties are the same in all directions. For fusion, neutron energy isotropy is an important measurement that analyzes the streams of neutrons coming from the device and how uniform they are. This is critical because so-called isotropic fusion plasmas suggest a stable, thermal plasma that […] Quantum computers have the potential of outperforming classical computers on some optimization and computational tasks. Compared to classical systems, however, quantum systems are more prone to errors, as they are more sensitive to noise and prone to so-called decoherence. Go to Source A research team from Japan has developed a unified model to scale the transitional pressure development in a one-dimensional flow. This achievement provides a better understanding of how pressure fields build up in the confined fluid system for various acceleration situations, which might be applicable to biomechanics-related impact problems, such as human brain injuries caused […] How can the latest technology, such as solar cells, be improved? An international research team led by the University of Göttingen is helping to find answers to questions like this with a new technique. For the first time, the formation of tiny, difficult-to-detect particles—known as dark excitons—can be tracked precisely in time and space. These […] An article published in the journal Optica describes the development of a new experimental device that explores the boundary between classical and quantum physics, allowing the simultaneous observation and investigation of phenomena from both worlds. Go to Source Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team led by Penn State physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations. Go […] Researchers at the University of Oxford have pioneered a new approach to simulate turbulent systems, based on probabilities. The findings appear in the journal Science Advances. Go to Source |
