The same goes for power lines that transmit electricity between cities. In fact, around 10 percent of the generated energy is lost in the transmission of electricity. That's because the electrons that carry electric charge do so as free agents, bumping and grazing against other electrons as they move collectively through power cords and transmission lines. All this jostling generates friction, and, ultimately, heat. /news/2023-07-physicists-generate-snapshots-fermion-pairs.html General Â鶹ÒùÔºics Thu, 06 Jul 2023 14:00:01 EDT news607870293 Spin is the intrinsic magnetic moment of a particle—an electron, for example. It is a fundamental magnitude, like mass and charge. Simply put, it is as if the particle had a magnet inside it that enabled it to interact, even while at rest, not only with the spins of other particles but also with external magnetic fields. /news/2022-10-liquid-realistic.html Quantum Â鶹ÒùÔºics Tue, 11 Oct 2022 11:10:23 EDT news584705420 Topological materials that possess certain atomic-level symmetries, including topological insulators and topological semi-metals, have elicited fascination among many condensed matter scientists because of their complex electronic properties.

While identical bosons like to congregate, identical fermions tend to be antisocial. However, in one dimension—imagine particles that can only move on a line—bosons can become as stand-offish as fermions, so that no two occupy the same position. Now, new research shows that the same thing—bosons acting like fermions—can happen with their velocities. The finding adds to our fundamental understanding of quantum systems and could inform the eventual development of quantum devices. /news/2020-03-quantum-copycat-bosons-fermions.html Quantum Â鶹ÒùÔºics Fri, 27 Mar 2020 18:15:28 EDT news504551686 Simulating computationally complex many-body problems on a quantum simulator has great potential to deliver insights into physical, chemical and biological systems. Â鶹ÒùÔºicists had previously implemented Hamiltonian dynamics but the problem of initiating quantum simulators to a suitable quantum state remains unsolved. In a new report on Science Advances, Meghana Raghunandan and a research team at the institute for theoretical physics, QUEST institute and the Institute for quantum optics in Germany demonstrated a new approach. While the initialization protocol developed in the work was largely independent of the physical realization of the simulation device, the team provided an example of implementing a trapped ion quantum simulator. /news/2020-03-quantum-simulators-sympathetic-cooling.html Quantum Â鶹ÒùÔºics Fri, 13 Mar 2020 09:32:59 EDT news503310774
