On the road to conductors of the future

Superconductivity in hydrogen sulfide

16-Sep-2020

Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In ...

Attention, the electron is too fast!

Why do different measurements of material properties sometimes give different results?

02-Sep-2020

It is very hard to take a photo of a hummingbird flapping its wings 50 times per second. The exposure time has to be much shorter than the characteristic time scale of the wing beat, otherwise you will only see a colorful blur. A very similar problem is encountered in solid-state physics, where ...

A topography of extremes

On the track of unconventional superconductivity, researchers are charting unknown territory

31-Aug-2020

An international team of scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Max Planck Institute for Chemical Physics of Solids, and colleagues from the USA and Switzerland have successfully combined various extreme experimental conditions in a completely unique way, revealing ...

Superconduction: Cuprate-like behavior in a nickel-oxide film

Two-dimensional electron gas discovered

21-Jul-2020

Superconductors transmit electric current without loss at any distance and play an important role in quantum computers and medical imaging. But the stars among the electrical conductors work exclusively at extremely low temperatures. Since the discovery of high-temperature superconducting ...

Superconductors with ‘zeitgeist’ – when materials differentiate between the past and the future

Novel superconductors are able to spontaneously generate constant internal magnetic fields

20-May-2020

Physicists at TU Dresden have discovered spontaneous static magnetic fields with broken time-reversal symmetry in a class of iron-based superconductors. This exceptional property calls for new theoretical models and may become important in quantum computing. What happened yesterday and what will ...

New way of developing topological superconductivity discovered

Quantum research unifies two ideas offering an alternative route to topological superconductivity

27-Apr-2020

A pencil shaped semiconductor, measuring only a few hundred nanometers in diameter, is what researches from the Center for Quantum Devices, Niels Bohr Institute, at University of Copenhagen, in collaboration with Microsoft Quantum researchers, have used to uncover a new route to topological ...

Shaking off the correlated-electron traffic jam

17-Mar-2020

An international team of researchers from Switzerland, Germany, the USA and Great Britain has uncovered an anomalous metallic behavior in an otherwise insulating ceramic material. The team used ultrashort light pulses with a wide range of colors to watch what happens when the insulating quasi ...

Manipulating atoms to make better superconductors

05-Mar-2020

Scientists have been interested in superconductors - materials that transmit electricity without losing energy - for a long time because of their potential for advancing sustainable energy production. However, major advances have been limited because most materials that conduct electricity have ...

New insights into superconducting processes

Physicists demonstrate energy quantization in high-temperature superconductors

12-Feb-2020

The development of a quantum computer that can solve problems, which classical computers can only solve with great effort or not at all - this is the goal currently being pursued by an ever-growing number of research teams worldwide. The reason: Quantum effects, which originate from the world of ...

Thorium superconductivity: Scientists discover a new high-temperature superconductor

11-Nov-2019

A group of scientists led by Artem Oganov, Professor at Skoltech and MIPT, and Dr. Ivan Troyan at the Institute of Crystallography of RAS have succeeded in synthesizing thorium decahydride (ThH10), a new superconducting material with a very high critical temperature (161 K). A truly remarkable ...
