Researchers at the Niels Bohr Institute created an intermediate state between superconductor and total insulation by controlling quantum fluctuations in tiny superconducting islands. This 'anomalous metallic regime' is a crucial step toward more controllable and reliable quantum devices.
Researchers confirm Kagome superconductor, a class of materials with star-shaped structure exhibiting unique electronic, magnetic, and superconducting properties. The discovery enables novel electronic components, such as superconducting diodes, with potential for energy-efficient quantum devices.
A research group led by Ryuichi Shindou proposes a new phenomenon where magnetic spin and electric charge are converted without energy loss in emergent superfluids of 2D materials. This conversion is made possible by exciton condensates, which exhibit dissipationless supercurrent flows.
Researchers have created a material system exhibiting unusually long-range Josephson effect, enabling macroscopic quantum coherence and potential for spintronic applications. The discovery of 'triplet' superconductivity, where electrons with the same spin circulate, expands possibilities for low-power consumption devices.
Researchers propose a new quantum circuit that mimics black hole behavior, allowing for the study of Hawking radiation. The proposed system uses a white hole and metamaterial to amplify Hawking radiation, potentially leading to breakthroughs in quantum communication.
Researchers at Aalto University have successfully demonstrated the quantum-mechanical interaction of two time crystals, a breakthrough that could enable the construction of a quantum computer operating at room temperature. The experiment involved exchanging magnetic quantum excitations, or magnons, between the two time crystals.
A team of scientists from Seoul National University and the Center for Correlated Electron Systems has made the first-ever observation of Cooper-pair density waves at an atomic level. The detection was achieved using Scanning Josephson Tunneling Microscopy, allowing researchers to directly measure Cooper-pairs in atomic resolution.
New research by National Physical Laboratory produces technology for accurate measurements of Planck's constant, a fundamental constant that relates frequency to energy. The technique enables the kilogram to be redefined in terms of this constant, providing a universal standard and greater long-term certainty for scientists.
Researchers at Georgia Institute of Technology have discovered a phenomenon that allows measurement of mechanical motion in nanostructures using the AC Josephson effect. The technique enables the identification and characterization of structural and mechanical properties of nanoparticles, including those of biological interest.
