Superconductivity breakthroughs: Cuprates earn their stripes
The Canadian research community on high-temperature superconductivity continues to lead this exciting scientific field with groundbreaking results coming hot on the heels of big theoretical questions.
Explainer: What is a superconductor?
Materials can be divided into two categories based on their ability to conduct electricity. Metals, such as copper and silver, allow electrons to move freely and carry with them electrical charge. Insulators, ...
Strings attached to future high temperature superconductivity
The behaviour of strongly correlated electron systems, such as high temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give ...
Scientists in China and US chart latest discoveries of iron-based superconductors
Superconductivity is a remarkable macroscopic quantum phenomenon, discovered just over a century ago. As temperature decreases to below a critical value, the electric resistance of a superconductor vanishes and the magnetic ...
Self-doping may be the key to superconductivity in room temperature
Swedish materials researchers at Linköping and Uppsala University and Chalmers University of Technology, in collaboration with researchers at the Swiss Synchrotron Light Source (SLS) in Switzerland investigated ...
Scientists capture ultrafast snapshots of light-driven superconductivity
A new study pins down a major factor behind the appearance of superconductivity—the ability to conduct electricity with 100 percent efficiency—in a promising copper-oxide material.
Pseudogap theory puts physicists closer to high temperature superconductors
(Phys.org) —Physicists are one step closer to developing the world's first room-temperature superconductor thanks to a new theory from the University of Waterloo, Harvard and Perimeter Institute.
Chemists exploring new material with 'next generation' computer hard drive possibilities
(Phys.org) —An attempt to uncover the 'holy grail' of a lossless energy source has inadvertently led to a study which could result in the next generation of high-speed, mass storage hard drives.
Light tsunami in a superconductor
Superconductors are materials which conduct electric currents without any resistance. At the Helmholtz-Zentrum Dresden-Rossendorf, an international research team headed by Professor Andrea Cavalleri from ...
Electronics like it cold, and 30 K cryocooler delivers
Superconductor 'flaws' could be key to its abilities
(Phys.org)—Many researchers studying superconductivity strive to create a clean, pure, perfect sample, but a team of physicists found that some flaws might hold the key to a material's unique abilities.
Development of 'Slater insulator' that rapidly changes from conductor to insulator at room temperature
Dr. Kazunari Yamaura, a Principal Researcher of the Strongly Correlated Materials Group, Superconducting Properties Unit, National Institute for Materials Science (NIMS), in joint work with a research group ...
Researchers find evidence of 'quantum critical point' in high temperature superconductivity material
The peculiar nature of molecular hydrogen vibration under high pressure
Most of our Universe consists of hydrogen atoms, which are often found under extraordinarily high pressure as high as tens of millions of times the atmospheric pressure of Earth. Understanding the exotic physics ...
