superconductors

Nature Communications, Published online: 05 May 2026; doi:10.1038/s41467-026-72651-x Recently, there has been growing interest in realizing quantum heat engines using superconducting circuits. Here the authors demonstrate a cyclic quantum heat engine based on superconducting circuits, showing controlled heating, cooling, and positive work extraction, with measured power and efficiency in agreemen…

Hi What is the relationship between superconductors and gravity? Eugene podkletnov came up with some interesting findings. The first experiment centered on a spinning superconducting disk and the possibility of slight weight reduction above it .

Scientists just revealed a hidden quantum “dance” that could reshape superconductivity. For the first time, scientists have directly visualized the quantum process behind superconductivity, a phenomenon in which electrons pair up and allow electricity to flow with no resistance at very low temperatures. The outcome was not what researchers anticipated. In a study published April [...]

Nature Communications, Published online: 30 April 2026; doi:10.1038/s41467-026-71938-3 Previous studies of vortex Majorana zero modes (MZMs) in iron-based superconductors have predominantly considered the case where magnetic field is parallel to the Dirac axis. Here, the authors focus on vortices oriented perpendicular to the Dirac axis, finding that such vortices are more favorable for observing…

Parts used in aircraft engines, power plants, and other high-temperature machines must survive extreme stress for long periods of time. Many of these parts are made from tough materials called superalloys, such as Inconel 718. These materials are designed to handle heat and pressure, but they still face a common problem: tiny cracks often begin […] The post This new method could make jet engine p…

basics Examples In solid state physics, by super-insulators one refers to meaterials which at very low but non-vanishing temperature have effectively unbounded electrical resistance. This phenomenon may be understood as the “EM-dual” to that of superconductors. Generalized to color charge, this notion plays a central role in the dual superconductor model of confinement.

Batteries bad The article linked above says batteries are problematic in space. I propose a flywheel, which is suited to the Lunar environment. 1) It is in vacuum already. 2) Magnetic suspension is less demanding in 1/6 gravity. 3) Superconductors need very low temperatures which are... Read more

In a breakthrough experiment, scientists directly imaged how particles pair up in a system that mimics superconductors. Instead of behaving independently, the pairs moved in a synchronized, dance-like pattern—something never predicted before. This suggests a major gap in the classic theory of superconductivity.

Nature Physics, Published online: 23 April 2026; doi:10.1038/s41567-026-03272-w Magnetic fields usually weaken superconductivity. By contrast, a material platform is demonstrated where applying a moderate field induces superconductivity.

Nature Physics, Published online: 23 April 2026; doi:10.1038/s41567-026-03266-8 The link between the strange metal with its linear-in-temperature resistivity and superconductivity is ambiguous. Now, a channel in the normal state whose scattering rate is linear in temperature is shown to drive superconductivity in FeTe1−xSex.

Nature, Published online: 23 April 2026; doi:10.1038/s41586-026-10547-y Field re-entrant superconductivity in Eu-doped infinite-layer nickelates

Scientists have found a new way to influence superconductivity by adjusting a material’s environment. Researchers have uncovered new evidence that superconductivity can be steered by a material’s surroundings, opening a potential path toward electronics that waste far less energy. Instead of changing the material itself, the team showed that subtle environmental tuning can reshape how [...]

In 1994 superconductivity was discovered in strontium ruthenate (Sr2RuO4). This attracted considerable interest because it had a perovskite crystal structure , just like the cuprates. Furthermore, it was a stoichiometric compound and so not plagued by impurities like the cuprates. In 1998, things got more interesting when NMR Knight shift measurements were interpreted as evidence for triplet supe…
