Properties of materials are often defined by imperfections in their atomic structure, especially when the material itself is just one atom thick, such as graphene. Researchers at the University of Vienna have now developed a method for controlled creation of such imperfections into graphene at length scales approaching the macroscopic world. These results, confirmed by atomically resolved microscope images and published in the journal Nano Letters, serve as an essential starting point both for tailoring graphene for applications and for the development of new materials.
Electrons are ubiquitous among atoms, subatomic tokens of energy that can independently change how a system behaves -- but they also can change each other. An international research collaboration found that collectively measuring electrons revealed unique and unanticipated findings.
Researchers have managed to create a stable giant vortex in interacting polariton condensates, addressing a known challenge in quantized fluid dynamics. The findings open possibilities in creating uniquely structured coherent light sources and exploring many-body physics under unique extreme conditions.
A study led by University of Minnesota physics researchers has discovered that a unique superconducting metal is more resilient when used as a very thin layer.
Researchers from the University of Vienna, the Austrian Academy of Sciences and the Perimeter Institute report in the latest issue of Physical Review Letters that nonlocality is a universal property of the world, regardless of how and at what speed quantum particles move.
A study led by University of Minnesota researchers uncovered a property of magnetic materials that will allow engineers to develop more efficient spintronic devices in the future, which could lead to faster and more efficient computing and data storage.
By shining laser light on semiconducting moiré superlattices formed by stacking two atomically thin materials -- monolayer tungsten diselenide (WSe2) and monolayer molybdenum diselenide (MoSe2) -- a team led by researchers at the University of California, Riverside, and Academia Sinica in Taiwan found a new class of electronic excited states called "moiré trions." The study opens up new opportunities to develop trion-based quantum optical emitters and offers new approaches to explore moiré physics.
Using an ultrafast transmission electron microscope, researchers from the Technion - Israel Institute of Technology have, for the first time, recorded the propagation of combined sound and light waves in atomically thin materials. The experiments were performed in the Robert and Ruth Magid Electron Beam Quantum Dynamics Laboratory headed by Professor Ido Kaminer, of the Andrew and Erna Viterbi Faculty of Electrical & Computer Engineering and the Solid State Institute.
In a decade-long quest, scientists at Berkeley Lab, the University of Hawaii, and Florida International University uncover new clues to the origins of the universe - and land new chemistry for cleaner combustion engines.
Last year, Anupam Mazumdar, a physicist from the University of Groningen, proposed an experiment that could conclusively prove whether gravity is a quantum phenomenon. In a new article, published on June 4, 2021 in Physical Review Research, he describes how two types of noise could be reduced and suggests that quantum interference could be applied in the production of a sensitive instrument that could detect movements of objects ranging from butterflies to burglars and black holes.
