futureStrongest resistive magnet created with 41.4 tesla

National magnet lab reached a record of 41.4 teslas at 1:10 p.m. on Aug. 21 with a resistive magnet. It was the culmination of two and a half intense years of design and development. In so doing, the lab reclaimed …

materialsMore understanding of other high temperature superconductors

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the …

materialsMajorana fermion, a particle that’s its own antiparticle

In 1928, physicist Paul Dirac made the stunning prediction that every fundamental particle in the universe has an antiparticle – its identical twin but with opposite charge. In 1937, another brilliant physicist, Ettore Majorana, introduced a new twist: He predicted …

materialsCarbon Superconductivity raised from 11 kelvin up to 57 kelvin

Researchers at North Carolina State University have significantly increased the temperature at which carbon-based materials act as superconductors, using a novel, boron-doped Q-carbon material. The previous record for superconductivity in boron-doped diamond was 11 Kelvin, or minus 439.60 degrees Fahrenheit. …

materialSecret of Iron Superconductors discovered

Due to magnetism iron should – theoretically – be a poor superconductor. Nevertheless certain iron based materials possess fine superconducting properties. Why? Because the five unbound electrons found in iron – as a result of individual modes of operation, it …

controversialEMdrive inventor Shawyer’s latest information on military applications and superconducting EMDrive progress

Roger Shawyer, SPR Ltd, invented the EMdrive and recently gave an EMdrive presentation to the UK Defence Academy Shrivenham. EmDrive is the first true Propellantless Propulsion technology. High frequency electrical energy is directly converted to thrust. It is a resonant …

controversialIf EMdrive is real and scales with Q factor then we get almost Star Trek level Technology

Adam Crowl considers spaceships if EM-Drive is verified as a real thing. If the NASA emdrive performance of 1.2 millinewtons per kilowatt. 8.3 TeraWatts of power would be needed to provide 10 million newtons of thrust to accelerate a 1000 …

futureGoogle on track to make quantum computer faster than classical computers within 7 months

John Martinis, one of Google’s quantum computing gurus, laid out Google’s “stretch goal”: to build and test a 49-qubit (“quantum bit”) quantum computer by the end of 2017. This computer will use qubits made of superconducting circuits. Each qubit is …

physicsSpectroscopic evidence of a new energy scale for superconductivity in H3S

The discovery of a superconducting phase in sulfur hydride under high pressure with a critical temperature above 200 K has provided fresh impetus to the search for superconductors at ever higher temperatures. Although this system displays all of the hallmarks of …

physicsCornell developing transition metal dichalcogenides which could make topological superconductor and quantum computers

Transition metal dichalcogenides (TMDs), materials offer several key features not available in graphene and are emerging as next-generation semiconductors. TMDs could realize topological superconductivity and thus provide a platform for quantum computing. “Our proposal is very realistic – that’s why …
