Penn Physicists Create Hybrid Light-Matter Particles That Switch Optical Signals at 4 Femtojoules, Pointing Toward All-Optical Computing
University of Pennsylvania researchers demonstrated strongly nonlinear exciton-polaritons that switch optical signals at 4 femtojoules—a record low for 2D polariton systems—using a MoSe₂ monolayer inside a photonic crystal nanocavity.
Hubble's Dracula's Chivito Is the Largest Planet-Forming Disk Ever Observed, Spanning 40 Times the Solar System and 10 to 30 Jupiter Masses
NASA's Hubble has imaged IRAS 23077+6707, a protoplanetary disk nicknamed Dracula's Chivito that spans nearly 400 billion miles and shows asymmetric filaments unlike any disk seen before.
Bicharracosaurus dionidei, a 20-Meter Patagonian Sauropod, Could Be the First Late Jurassic Brachiosaurid From South America
A German-Argentine team has described a 155-million-year-old long-necked dinosaur from Chubut, mixing brachiosaurid and diplodocid traits.
JWST's COSMOS-Web Survey Maps 164,000 Galaxies Into the Most Detailed Cosmic Web Yet, Stretching Back to When the Universe Was a Billion Years Old
A UC Riverside-led team used the largest JWST observing program to trace galaxies along the cosmic web from today out to redshift z ~ 7, and released the full pipeline and catalog publicly.
Aalto Team Couples a Helium-3 Time Crystal to a Mechanical Oscillator, the First Link Between a Time Crystal and an External Device
Researchers at Aalto University demonstrated they can connect a continuous time crystal to a mechanical oscillator without destroying it, turning the exotic quantum state into an optomechanics-like platform that ran for up to 108 cycles.
Cal Poly Physicists Propose Flux-Switching Floquet Engineering, a Path to Stable Exotic Quantum Matter Without Static Analogs
Powell and Buchalter show in Physical Review B that periodically switched magnetic fluxes through a Harper-Hofstadter lattice can produce topological phases that no equilibrium material can host.
JWST Finds a Massive Early-Universe Galaxy That Doesn't Spin, the First Slow Rotator Confirmed Less Than 2 Billion Years After the Big Bang
A UC Davis-led team using JWST has measured the kinematics of XMM-VID1-2075 at redshift 3.45 and found no detectable rotation, a property previously seen only in mature nearby galaxies.
Wurzburg team confirms 40-year-old Kardar-Parisi-Zhang growth law in two dimensions using exciton-polariton condensates
Physicists at the University of Wurzburg used a gallium arsenide quantum film cooled to -269.15 C to measure KPZ scaling exponents in 2D, four years after the 1D version was confirmed.
Astronomers Detect a Thin Atmosphere on (612533) 2002 XV93, the First Trans-Neptunian Object Beyond Pluto Found With One
A 500-kilometer plutino in the Kuiper Belt shows refractive signs of a 100-200 nanobar atmosphere, a discovery published May 4 in Nature Astronomy that astronomers say challenges models of which small icy worlds can hold gas.
Oxford Team Achieves First-Ever Quadsqueezing on a Single Trapped Ion, Generating the Fourth-Order Effect Over 100 Times Faster Than Expected
A University of Oxford group has experimentally demonstrated quadsqueezing, a fourth-order quantum interaction long thought too weak to observe, by harnessing non-commutativity between two laser-driven forces on a single trapped ion.
New JIRAM Analysis Suggests Io's Lava Lakes Radiate an Order of Magnitude More Power Than M-band Surveys Reported
A Mura et al. preprint using Juno's JIRAM data argues prior single-band thermal estimates of Io's paterae missed the colder crust that dominates output, lifting one lava lake's estimate from 7 GW to 80 GW.
Warwick's RAVEN AI Pipeline Validates 118 New Exoplanets in TESS Data, Adding Nearly 1,000 Fresh Candidates
A University of Warwick team applied a new machine-learning pipeline called RAVEN to four years of TESS observations, statistically validating 118 short-period planets and surfacing roughly 1,000 candidates not previously catalogued.
