Magnetic field turns handed superconductor into liquid crystal-like nematic state

16-Sep-2021

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and RWTH Aachen University have suggested a surprising connection between the nematic behavior of a superconductor in a magnetic field — a state that resembles liquid crystals used in LCDs — and its ...

New mechanism of superconductivity discovered in graphene

Placing a 2D Bose-Einstein condensate in the vicinity of a graphene layer confers superconductivity to the material

20-Jul-2021

Superconductivity is a physical phenomenon where the electrical resistance of a material drops to zero under a certain critical temperature. Bardeen-Cooper-Schrieffer (BCS) theory is a well-established explanation that describes superconductivity in most materials. It states that Cooper pairs of ...

Ultrathin semiconductors electrically connected to superconductors for the first time

New properties and phenomena

07-Jul-2021

For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they ...

Exotic superconductors: The Secret that wasn’t there

New measurements show: An allegedly sensational effect does not exist at all

23-Jun-2021

A single measurement result is not a proof - this has been shown again and again in science. We can only really rely on a research result when it has been measured several times, preferably by different research teams, in slightly different ways. In this way, errors can usually be detected sooner ...

Researchers uncover unique properties of a promising new superconductor

Material could be used in future quantum computing applications

18-Jun-2021

An international team of physicists led by the University of Minnesota has discovered that a unique superconducting metal is more resilient when used as a very thin layer. The research is the first step toward a larger goal of understanding unconventional superconducting states in materials, ...

A material-keyboard made of graphene

Insulator and superconductor in the same material

07-May-2021

Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties ...

Long live superconductivity!

Pathbreaking advance: Short flashes of light with sustaining impact

09-Feb-2021

Superconductivity – the ability of a material to transmit an electric current without loss – is a quantum effect that, despite years of research, is still limited to very low temperatures. Now a team of scientists at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in ...

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 ...
