New material with wavy layers of atoms exhibits unusual superconducting properties
MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves over and over to create a macroscopic sample that c.....»»
Tracking plasma progression in a picosecond: Physicists develop ultra-fast laser method to study high-density plasmas
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term—the metal is nearly 200,000 degrees Fahrenheit. With the short.....»»

Early dark energy could resolve cosmology"s two biggest puzzles
A new study by MIT physicists proposes that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe evolved......»»
Generating spin currents directly using ultrashort laser pulses
An international team of physicists has found that it is possible to generate spin currents directly using certain kinds of ultrashort laser pulses. In their study, published in the journal Physical Review Letters, the group used a linearly polarized.....»»
Floquet engineering tunes ultracold molecule interactions and produces two-axis twisting dynamics
The interactions between quantum spins underlie some of the universe's most interesting phenomena, such as superconductors and magnets. However, physicists have difficulty engineering controllable systems in the lab that replicate these interactions......»»
Discovery of a new phase of matter in 2D defies normal statistical mechanics
Physicists from the Cavendish Laboratory in Cambridge have created the first two-dimensional version of the Bose glass, a novel phase of matter that challenges statistical mechanics. The details of the study have been published in Nature......»»
Scientists prove long-standing wave amplification theory
Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by bouncing "twisted waves"—those with angular moment.....»»
Physicists capture images of atoms flowing along a boundary without resistance despite obstacles in their path
Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls......»»
Physicists capture first thickness-dependent transitions in two-dimensional magnetic material
A team of physicists from The University of Hong Kong (HKU), Texas Tech University (TTH), and the University of Michigan (UMich), has made an important discovery in the study of van der Waals (vdW) magnetic materials, a special class of materials wit.....»»

Magnetic fields can engineer flat bands in twisted graphene layers to create a new playground for exotic physics, RIKEN physicists have shown......»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
Superconductivity study confirms existence of edge supercurrents
Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must.....»»
Heaviest antimatter observation yet will fine-tune numbers for dark matter search
In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic antimatter particles......»»
