Microscope allows ultrafast nanoscale manipulation while tracking energy dynamics
Since the early 2010s, ultrafast probing of materials at atomic-level resolution has been enabled by terahertz scanning tunneling microscopes (THz-STM). But these devices can't detect the dissipation of energy that happens during events such as when.....»»
New mechanism found for generating giant vortices in quantum fluids of light
Anyone who has drained a bathtub or stirred cream into coffee has seen a vortex, a ubiquitous formation that appears when fluid circulates. But unlike water, fluids governed by the strange rules of quantum mechanics have a special restriction: as was.....»»
Breakthrough greatly enhances ultrafast resolution achievable with X-ray free-electron lasers
A large international team of scientists from various research organizations, including the U.S. Department of Energy's (DOE) Argonne National Laboratory, has developed a method that dramatically improves the already ultrafast time resolution achieva.....»»
How the trap-jaw ant got its ultrafast bite
Powerful and deadly, the bite of a trap-jaw ant is renowned throughout the animal kingdom. Unlike normal gripping jaws, which rely on muscles to open and close, the trap-jaw latches itself open, storing energy like a stretched spring. When released,.....»»
Through the looking glass: Artificial molecules open door to ultrafast polaritonic devices
Researchers from Skoltech and the University of Cambridge have shown that polaritons, the quirky particles that may end up running the quantum supercomputers of the future, can form structures behaving like molecules—and these "artificial molecules.....»»

High-resolution, terahertz-driven atom probe tomography
Materials scientists must be able to exert ultrafast control of matter using a strong electromagnetic field on the atomic scale to understand the ionization dynamics and excitations in solids. Researchers can couple picosecond duration terahertz puls.....»»
Ultrafast electron dynamics in space and time
Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only impo.....»»
New advances using exotic matter may lead to ultrafast computing
In the 196zeroes, an exotic phase of matter known as an excitonic insulator was proposed. Decades later, evidence for this phase was found in real materials. Recently, particular attention has centered on Ta2NiSe5 because an excitonic insulator phase.....»»
Dual character of excitons in the ultrafast regime: Atomic-like or solid-like?
Excitons are quasiparticles which can transport energy through solid substances. This makes them important for the development of future materials and devices—but more research is needed to understand their fundamental behavior and how to manipulat.....»»

Researchers from the Cluster of Excellence "CUI: Advanced Imaging of Matter" have achieved a breakthrough—creating a completely new type of plasma by combining state-of-the-art technologies using ultrashort laser pulses and ultracold atomic gases......»»
TikTok emerges as a political battleground in Navalny-stirred Russia
TikTok has crafted a number of policies over the years to distance itself from the often-messy political fray, but its users continue to have other agendas in mind. In Russia, a tug-of-war has emerged on the social network. On one side are young peop.....»»
Bimeronium: A new member of the topological spin textures family
Topological spin textures in magnetic systems are intriguing objects that exhibit exotic physics and have potential applications in information storage and processing. The most fundamental and exemplary topological spin texture is called the skyrmion.....»»
What the new James Bond game should (and shouldn’t) take from Hitman 3
IO Interactive's Hitman trilogy has laid a great foundation for its Project 077, but the formula will need to be shaken, not stirred, in order to perfect it......»»
EV charging firm FreeWire closes $50 million funding round
Six-year-old FreeWire’s products are used to charge EVs and power events and construction sites. It plans to have more than 2,500 ultrafast charging stations by 2025......»»
