Physicists have confirmed a quantum state predicted over 50 years ago by pairing electrons in an artificial atom on a superconductor, demonstrating the behavior of paired electrons and creating a basic version of superconductivity. This discovery has implications for advancing the understanding of superconductivity in nanoscale structures and its potential application in modern quantum computers.
Researchers from the Department of Physics at Universität Hamburg have successfully observed a quantum state predicted over 50 years ago by Japanese theoreticians. By creating an artificial atom on a superconductor surface, the researchers paired electrons in a quantum dot, resulting in the smallest version of a superconductor. This breakthrough has implications for the development of nanoscale electronic devices and quantum computers.
MIT physicists have successfully imaged particle pairings in a cloud of atoms, providing new insights into the behavior of electrons in superconducting materials. The discovery, documented in the journal Science, could assist in understanding superconductivity and further development of heat-free electronics. The images shed light on how electrons form superconducting pairs that glide through materials without friction. The observations can serve as a visual blueprint for how electrons may pair up in superconducting materials and may also help describe how neutrons pair up to form superfluids in neutron stars.
Physicists at MIT have captured the first snapshots of fermion pairs, shedding light on how electrons form superconducting pairs. By studying the behavior of fermions in the form of potassium-40 atoms, the researchers were able to observe the particles pairing up, even when separated by a small distance. The observations provide a visual blueprint for how electrons may pair up in superconducting materials and may also help understand how neutrons pair up in neutron stars. The findings could contribute to the development of room-temperature superconductors and zero-loss devices.
MIT physicists have captured the first images of fermion pairs, including electrons, protons, neutrons, and certain types of atoms, providing insights into how electrons pair up in superconducting materials. By studying a cloud of potassium-40 atoms under ultracold conditions, the researchers observed the pairing behavior and interesting patterns, such as checkerboards formed by the pairs. The findings could help advance the understanding of superconductivity and potentially lead to the development of room-temperature superconductors.
Ultrahigh-resolution and low-temperature angle-resolved photoemission spectroscopy have been used to directly observe a nodeless, nearly isotropic, and orbital-independent superconducting gap in the momentum space of two exemplary CsV3Sb5-derived kagome superconductors. The gap structure is robust to the appearance or absence of charge order in the normal state, providing indispensable information on the electron pairing symmetry of kagome superconductors and advancing our understanding of the superconductivity and intertwined electronic orders in quantum materials.
