Quantum Annealer Improves Understanding of Quantum Many-Body Systems

27-Jun-2024 - Physicists have long been pursuing the idea of simulating quantum particles with a computer that is itself made up of quantum particles. This is exactly what scientists at Forschungszentrum Jülich have done together with colleagues from Slovenia. They used a quantum annealer to model a real-life ...

Frozen noble gas in the accelerator

29-May-2024 - Researchers at European XFEL in Schenefeld near Hamburg have taken a closer look at the formation of the first crystallisation of nuclei in supercooled liquids. They found: The formation starts much later than previously assumed. The findings could help to better understand the creation of ice in ...

Artificial intelligence calculates phase diagrams

This AI could even automate scientific experiments in the future

17-May-2024 - Researchers at the University of Basel have developed a new method for calculating phase diagrams of physical systems that works similarly to ChatGPT. This artificial intelligence could even automate scientific experiments in the future. A year and a half ago, ChatGPT was released, and ever ...

When electrons slowly vanish during cooling

04-Aug-2023 - Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of quantum mechanics. ...

New X-ray imaging technique to study the transient phases of quantum materials

An international team of researchers has demonstrated for the first time the use of a new lensless ultrafast X-Ray method to image phase transitions

27-Dec-2022 - The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing the growth of a new phase in a solid is not easy, due in-part to ...

Using machine learning to better understand how water behaves

22-Dec-2022 - Water has puzzled scientists for decades. For the last 30 years or so, they have theorized that when cooled down to a very low temperature like -100C, water might be able to separate into two liquid phases of different densities. Like oil and water, these phases don’t mix and may help explain ...

High entropy alloys: structural disorder and magnetic properties

"High-entropy alloys are an extremely diverse and exciting class of materials”

26-Oct-2022 - High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic behaviour. Now, a team at BESSY II in collaboration with Ruhr University Bochum, BAM, Freie ...

New Fur for the Quantum Cat

Quantum materials: entanglement of many atoms discovered for the first time

07-Sep-2022 - Be it magnets or superconductors: materials are known for their various properties. However, these properties may change spontaneously under extreme conditions. Researchers at the Technische Universität Dresden (TUD) and the Technische Universität München (TUM) have discovered an entirely new ...

Researchers discover a material that can learn like the brain

24-Aug-2022 - EPFL researchers have discovered that Vanadium Dioxide (VO2), a compound used in electronics, is capable of “remembering” the entire history of previous external stimuli. This is the first material to be identified as possessing this property, although there could be others. Mohammad Samizadeh ...

A look into the magnetic future

Researchers at PSI and ETH Zurich have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes

06-Apr-2022 - This view into processes that take place within so-​called artificial spin ice could play an important role in the development of novel high-​performance computers. When water freezes to form ice, the water molecules, with their hydrogen and oxygen atoms, arrange themselves in a complex ...
