Sensing the Quantum Limit in Scanning Tunnelling Spectroscopy

A newly published study from the Max Planck Institute reveals what would happen if an electric current no longer flowed, but trickled instead. What would happen if an electric current no longer flowed, but trickled instead? This was the question investigated by researchers working with Christian Ast at the Max Planck Institute for Solid State […]

Hydrogen Sulfide Becomes Superconductive at Minus 70 Degree Celsius

New research from the Max Planck Institute and the Johannes Gutenberg University reveals that hydrogen sulfide loses its electrical resistance under high pressure at minus 70 degrees Celsius. Up until now, no material has been able to conduct current with no resistance at such high temperatures: Researchers at the Max Planck Institute for Chemistry in […]

Why Some Crystals Jump and Others Crumble

A team of researchers has discovered the force that makes the organometallic compound palladium hexafluoroacetylacetonate jump. This thermosalient effect could potentially be applied in artificial muscles and actuators. Crystals are not as stationary as you might think. A crystal of an organometallic compound containing palladium, for example, downright jumps from a hotplate once it reaches […]

Superconductivity without Cooling

New research details how scientists used an infrared laser pulse to briefly modify the structure of a high-temperature superconductor, removing its electrical resistance at room temperature. Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for […]

A Nanolamp with Lightning-Fast Switch

Scientists have developed a light source which converts an electrical voltage pulse into a light pulse by means of a single molecule, possibly serving as a prototype for nano-components that convert electrical into optical signals with gigahertz frequencies. Information is processed and transmitted by ever-smaller components, sometimes with electrons and sometimes with light. Scientists at […]

Atomic Scale Imaging of Magnetic Structures

Scientists from the Max Planck Institute for Solid State Research use atomic scale imaging of magnetic structures to study new aspects of high-temperature superconductivity. Superconductors raise many hopes, especially materials which lose their electrical resistance at quite high temperatures – be it for high-performance medical imaging technologies, the energy transportation or for maglev trains. High-temperature […]

Researchers Consider the Anticrystal

Physicists show that the anticrystal, a theoretical solid that is completely disordered, should undergird our understanding of most materials. For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make. Now physicists […]

Molecular Photons Interfaced with Alkali Atoms for the First Time

In a newly published study, scientists describe the optical interaction between Fourier-limited photons from a single organic molecule and atomic alkali vapors. It may be surprising, but in physics the terrain of atoms and the territory of organic molecules are worlds apart. Therefore, in order to have a molecule communicate optically with atoms, the physicists […]

Quantum Computation in Diamond

An international team of physicists has discovered a way to control the quantum system of a diamond with a small number of nitrogen impurities. Computers do not necessarily have to perform error-free calculations in order to provide perfect results – they only need to correct their errors in a reliable way. And this will become […]

A Growing Understanding of the Conditions Required for Superconductivity

Two newly published studies improve scientists’ understanding of the conditions required for superconductivity and how it can be achieved at realistic temperatures. Even physics can give pointers for energy saving. An international team working together with the Center for Quantum Materials, run by the Max Planck Society in conjunction with the University of British Columbia […]

insights into how superconducting materials interact with magnetic ones

An international team of physicists have gained new insights into how superconducting materials interact with magnetic ones, discovering charge density waves in ceramic yttrium and neodymium barium cuprates. Whether a material conducts electricity without losses is not least a question of the right temperature. In future it may be possible to make a more reliable […]
