Published How atomic nuclei vibrate


Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists report that they can thus confirm the wave-like movement of nuclear material more precisely that ever before and that they have found no evidence of any deviation from the established force between atomic nuclei.
Published Scientists caught Hofstadter's butterfly in one of the most ancient materials on Earth


Researchers have revisited one of the most ancient materials on Earth -- graphite, and discovered new physics that has eluded the field for decades.
Published New insights into the origin of the Indo-European languages



An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
Published Family trees from the European Neolithic



The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.
Published A new type of quantum bit in semiconductor nanostructures


Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single terahertz laser pulse.
Published 'Quantum avalanche' explains how nonconductors turn into conductors



The study takes a new approach to answer a long-standing mystery about insulator-to-metal transitions.
Published Detection of bacteria and viruses with fluorescent nanotubes


The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses.
Published These bones were made for walking



The genetic changes that made it possible for humans to walk upright have been uncovered in a study that also shows how slight variations in skeletal proportions are linked to arthritis.
Published Unveiling the quantum dance: Experiments reveal nexus of vibrational and electronic dynamics


Scientists have demonstrated experimentally a long-theorized relationship between electron and nuclear motion in molecules, which could lead to the design of materials for solar cells, electronic displays and other applications that can make use of this powerful quantum phenomenon.
Published Theory for superfluid helium confirmed


Researchers have achieved a groundbreaking milestone in studying how vortices move in these quantum fluids. A new study of vortex ring motion in superfluid helium provides crucial evidence supporting a recently developed theoretical model of quantized vortices.
Published Researchers establish criterion for nonlocal quantum behavior in networks


A new theoretical study provides a framework for understanding nonlocality, a feature that quantum networks must possess to perform operations inaccessible to standard communications technology. By clarifying the concept, researchers determined the conditions necessary to create systems with strong, quantum correlations.
Published Butterflies and moths share ancient 'blocks' of DNA



Butterflies and moths share 'blocks' of DNA dating back more than 200 million years, new research shows.
Published New superconductors can be built atom by atom


The future of electronics will be based on novel kinds of materials. Sometimes, however, the naturally occurring topology of atoms makes it difficult for new physical effects to be created. To tackle this problem, researchers have now successfully designed superconductors one atom at a time, creating new states of matter.
Published Search for dark matter



Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a storage ring COSY.
Published Despite doubts from quantum physicists: Einstein's theory of relativity reaffirmed



One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all measurements to date confirm the equivalence principle, quantum theory postulates that there should be a violation. This inconsistency between Einstein's gravitational theory and modern quantum theory is the reason why ever more precise tests of the equivalence principle are particularly important. A team has now succeeded in proving with 100 times greater accuracy that passive and active gravitational mass are always equivalent -- regardless of the particular composition of the respective masses.
Published Controlling signal routing in quantum information processing



Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team has achieved unidirectional transport of signals in pairs of 'one-way streets'. This research opens up new possibilities for more flexible signaling devices.
Published Physicists work to prevent information loss in quantum computing



Nothing exists in a vacuum, but physicists often wish this weren't the case. If the systems that scientists study could be completely isolated from the outside world, things would be a lot easier. Take quantum computing. It's a field that's already drawing billions of dollars in support from tech investors and industry heavyweights including IBM, Google and Microsoft. But if the tiniest vibrations creep in from the outside world, they can cause a quantum system to lose information.
Published 'Toggle switch' can help quantum computers cut through the noise



What good is a powerful computer if you can't read its output? Or readily reprogram it to do different jobs? People who design quantum computers face these challenges, and a new device may make them easier to solve.
Published Humans' evolutionary relatives butchered one another 1.45 million years ago



Researchers have identified the oldest decisive evidence of humans' close evolutionary relatives butchering and likely eating one another.
Published Nanophotonics: Coupling light and matter



Researchers have developed a metasurface that enables strong coupling effects between light and transition metal dichalcogenides (TMDCs).
