In recent experiments involving hydrogels and water droplets, researchers have proposed that exposure to visible light could make water evaporate faster without heating it. However, direct evidence that light acts on water itself has proven elusive.
Physicists with the University of Illinois Urbana-Champaign's Grainger College of Engineering have identified a new form of superconducting behavior. Experiments on the metal uranium ditelluride reveal that Cooper pairs, the composite electron units responsible for superconductivity, can organize into nonuniform...
Superconductors are materials that conduct electricity with no resistance and expel magnetic fields when cooled to ultralow temperatures. And depending on their quantum structure, they can also showcase strange properties like magnetic levitation. But now things are getting a little weirder.
Once called a "pipe dream," quantum computers are now approaching practical use. Companies and research institutes around the world are in fierce competition to develop this technology, which has the potential to rapidly perform some calculations that are extremely difficult even for conventional supercomputers.
While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive. But this is what British physicist John Cockcroft and Irish physicist Ernest T.S. Walton had to do in the early 1930s while studying the structure of...
Imagine a proton catching a wave and surfing it to gain speed. While the imagery may seem wild, the premise of laser-driven ion acceleration has promise as an alternative to conventional accelerators. However, the ultrathin targets used to drive this increase in ion energy are vulnerable to the weak prepulse that...
EPFL researchers have developed a chip-based laser that keeps a very stable frequency across its tested operating range, without needing active electronic control. Their research is published in the journal Nature Photonics.
Working in close collaboration, researchers from Paderborn University, the University of Basel and Ruhr University Bochum have made a breakthrough in quantum communication. In their recently published paper in the journal Physical Review Letters, they demonstrate how special semiconductor nanostructures can be used to...
Many systems in nature can settle into several different stable states, with the final state depending on their starting conditions. However, the boundaries separating these states are often far more complicated than they first appear.
In the conventional diagram of an atom, the center depicts a nucleus-a spherical cluster of protons and neutrons. But that sphere is a simplification: nuclei can deform into exotic shapes that appear more like a pear, football or Frisbee. Understanding why and when nuclei distort is crucial for predicting and modeling...
Light scattered in tissue usually ceases to be a useful source of information. But what if, instead of forcing it to travel along a single path, we allowed it to wander a little differently each time? Scientists from ICTER tested this seemingly risky idea and showed that a series of measurements that differ from one...
Quantum technologies rely on qubits, units of information that can exist in combinations of the states 0 and 1 instead of being limited to one or the other like conventional bits. Qubits can become entangled, which means their states become linked in ways that cannot be explained by considering each qubit separately.
