Researchers from the Paihau-Robinson Research Institute, part of Te Herenga Waka Victoria University of Wellington, will soon have an experiment on-board the ISS - a powerful superconducting electromagnet that could form the basis of next-gen electric propulsion. Thrilled that my first ever article for @IEEESpectrum is about some very cool NZ science

…so what is it, what does all this represent ? Technical breakthroughs in areas like room temperature #SuperConductivity and #Solar cell efficiencies have the power to reshape our world. Now it’s becoming clear there is something here with us demonstrating technology that leaps well beyond our own. They will have successfully run many of the gauntlets we face to achieve that. We should at the least be paying attention

"This year, superconductivity — the flow of electric current with zero resistance — was discovered in three distinct materials. Two instances stretch the textbook understanding of the phenomenon. The third shreds it completely. “It’s an extremely unusual form of superconductivity that a lot of people would have said is not possible,” said Ashvin Vishwanath, a physicist at Harvard University who was not involved in the discoveries."

Physicists continue exploring new superconductivity and superfluidity forms by experimenting with extreme temperatures and pressures. Discoveries such as high-temperature superconductors have revolutionized the field, but what else lies ahead? Could novel materials or exotic states of matter exhibit these properties at more practical conditions? Uncovering these could lead to breakthroughs in energy transmission, quantum computing, and other advanced technologies. #Physics #Superconductivity

Briefly: Our CSMC electromagnet works like a champ, proving out the second of 2 high-temperature superconducting magnet types needed for fusion: steady state and now pulsed current.

It was dramatic watching the testing (at MIT) in real time, like when it hit 50,000 amps current / 5.7 tesla field. #FusionEnergy #Climate #Magnets #Superconductivity

Excited to share a new colloquium by Prof. Andrea Cavalleri, a founding director of the MPI for the Structure and Dynamics of Matter 🎓✨ In his Nordita talk, he explores how coherent electromagnetic radiation can induce unexpected phases like magnetic order, ferroelectricity, and high-temperature superconductivity.

🔗 Watch the lecture here: enabla.com/pub/1119/about

Full abstract: In this colloquium, I will discuss how coherent electromagnetic radiation, when tuned to drive collective modes in quantum materials, can be used to induce unexpected dynamical phases. An illustrative set of examples will be discussed for the nonlinear control of the crystal lattice, which is used to induce magnetic order in paramagnetic materials, ferroelectricity in paraelectrics, non-equilibrium superconductivity at high temperatures, and other dynamical phases. These studies open up new directions in fundamental research but also expose a set of phenomena that will inevitably be encountered if one wishes to use quantum materials in ultra-high bit-rate applications.

Notes on #UAP Discussions : How would you introduce a class on "theoretical advances in novel propulsion systems " ?
if you were going to start with early history your candidates are primarily #Antigravity and #Electrostatics but a basic functional approach might start with concepts of mass levitation and associated phenomenologies like #Superconductivity, #Magnetohydrodynamics, #plasmas and #Solitons. Emphasis should be on the fact that there is more than one path to unconventional propulsion

Some 2022 results about #superconductivity are under attack for two reasons: (1) suspicious smoothing of noisy data and (2) refusing to share data "upon reasonable request".
nature.com/articles/d41586-024

"The journal [Nature Communications] has updated its policy for transparency to remove the word 'reasonable' so data are available only 'upon request'."

From Maarten van Kampen: By sharing data "you make yourself vulnerable. But I think it’s good. It is the way it should be.”
