Direct measurements of diamond melting under extreme pressure resolved a long-standing theory-experiment mismatch and could improve both fusion research and planetary models. Diamond is not only a gemstone. This exceptionally hard form of carbon is also used in the tiny capsules that surround fuel in inertial confinement fusion experiments, and researchers think carbon may form […]

Linear field theories Linear field theories form the classical counterparts to many important QFT's in condensed matter physics, modeling a wide range of materials, from the mundane (semiconductors), to the exotic (topological insulators and superconductors). Linear field theories are exactly soluble, and, when quantized, form great first approximations to complicated QFT's. Non-interacting parti…

Can a superconductor turn heat flow into a detectable electrical signal without the motion of magnetic vortices? This response, known as the Nernst effect, was long thought to be hidden because superconductors carry current without a voltage drop and screen the resulting electrical current. A recent…

MIT researchers created stable, air-resistant niobium diselenide—an ultrathin superconducting material—by growing it under graphene.

Future fusion reactors will rely on superconducting magnets that must keep working for years while exposed to energetic particles. A new head-to-head irradiation study shows that two candidate superconductors can respond very differently under the same electron-beam conditions. The layered cuprate Bi-2212 progressively lost its crystalline order and became fully amorphous, whereas the A15 superco…

What happens when a superconductor becomes so thin that electrons can no longer behave as if they were moving through an ordinary three-dimensional piece of metal? This question has been at the center of my recent work on quantum confinement in metallic films. Over the past few years, I have been developing this line of […]

No-insulation (NI) winding technology, combined with controlled bypass architecture, has become the dominant strategy for protecting REBCO insert magnets operating above 20 T.[1] Experiments in 2025–2026 have shown that quench tolerance depends not only on stored energy but, more critically, on the electro-thermo-mechanical coupling response of the coil assembly.[4] Key parameters include the int…

Dozens of materials today outperform the world’s most common superconductor— niobium-titanium (NbTi). But no competing material can beat niobium-titanium’s ability to be manufactured at scale and rolled out into usable wire. Two startups say that AI and robots could help close that gap. The San Francisco-based Periodic Labs and Cambridge, Mass.-based Quantum Formatics are searching for materials …

As much as we now know about superconductivity – where a material conducts electrical charge...

Magic-angle twisted bilayer graphene (TBG) exhibits superconductivity, and new research shows it remains stable even with strong electrostatic control.

Researchers observed robust two-dimensional superconductivity on the surface of γ-PtBi2, a Weyl semimetal, revealing a distinct vortex lattice.

Tensile strain applied to kagome metal CsV₃Sb₅ boosts its superconducting transition temperature to 3.6 Kelvin, while leaving charge density wave order intact.

Finnish startup S-Transistors, a spin-out from VTT Technical Research Centre of Finland, has raised €2.6 million in pre-seed funding to pioneer a fundamentally new class of  ICs based on superconducting […] The post Superconducting transistor startup raises €2.6m appeared first on Electronics Weekly .

For 30+ years, Berkeley Lab’s Advanced Light Source has aided studies of superconductors, topological insulators, and other key quantum materials.

Scientists have uncovered hidden complexity inside two ultrathin superconductors that seemed much simpler than they really are. Niobium diselenide and tantalum disulfide appeared to have a single superconducting state, but highly sensitive measurements revealed that each actually contains two strongly interacting states working so closely together that they masquerade as one.
