Quantum entanglement in quasiparticles: a stealth mode against disorder
Quantum entanglement in quasiparticles: a stealth mode against disorder
Würzburg physicists have discovered that quantum entanglement toughens up quasiparticles against impurity scattering - even when they are subject to strong disorder. Physicists at Julius-Maximilians-Universität Würzburg (JMU) have made a discovery that could boost the understanding of the role of entanglement in high-temperature copper oxide superconductors.

Mysterious object in the gap
Mysterious object in the gap
On May 29, 2023, the LIGO Livingston detector observed a mysterious signal, called GW230529. It originated from the merger of a neutron star with an unknown compact object, most likely an unusually light-weight black hole. With a mass of only a few times that of our Sun, the object falls into the "lower mass gap" between the heaviest neutron stars and the lightest black holes.

Progress in Quantum Physics: Researchers Tame Superconductors
An international team including researchers from the University of Würzburg has succeeded in creating a special state of superconductivity. This discovery could advance the development of quantum computers. Superconductors are materials that can conduct electricity without electrical resistance - making them the ideal base material for electronic components in MRI machines, magnetic levitation trains and even particle accelerators.

Spectroscopy and theory shed light on excitons in semiconductors
Research team led by Göttingen University make extremely fast, precise images for first time From solar panels on our roofs to the new OLED TV screens, many everyday electronic devices simply wouldn't work without the interaction between light and the materials that make up semiconductors. A new category of semiconductors is based on organic molecules, which largely consist of carbon, such as buckminsterfullerene.

High resolution techniques reveal clues in 3.5 billion-year-old biomass
Research team analyses organic material from the early Earth tracing its origin and composition To learn about the first organisms on our planet, researchers have to analyse the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time.
